Description

本発明は、可搬型センサに装着されるバッテリの不具合を調査する技術に関するものである。 The present invention relates to a technique for investigating a failure of a battery attached to a portable sensor.

近年、放射線を直接デジタルデータに変換可能であるＦＰＤ（Flat Panel Detector）等のＸ線検出器が実用化されている。そして、このＸ線検出器を用いて、照射されたＸ線により画像データを撮影する可搬型のカセッテ式センサ（以下、可搬型センサと称す）が実用化されている。なお、可搬型センサには、Ｘ線を変換する方式として、Ｘ線をシンチレータで光に変換した後にフォトダイオード等の半導体層で電荷に変換する間接変換方式がある。また、Ｘ線をアモルファスシリコン等の半導体層で電荷に変換する直接変換方式等があり、各方式でも半導体層に使用可能な材料が種々存在する。 In recent years, X-ray detectors such as FPD (Flat Panel Detector) capable of directly converting radiation into digital data have been put into practical use. A portable cassette-type sensor (hereinafter referred to as a portable sensor) that captures image data using irradiated X-rays using this X-ray detector has been put into practical use. As a method for converting X-rays in a portable sensor, there is an indirect conversion method in which X-rays are converted into light by a scintillator and then converted into electric charges by a semiconductor layer such as a photodiode. In addition, there is a direct conversion method in which X-rays are converted into electric charges in a semiconductor layer such as amorphous silicon, and there are various materials that can be used for the semiconductor layer in each method.

この可搬型センサは、当初、電力源と可搬型センサ自体とをケーブルで接続することで電力が供給されていた。しかし、撮影システムで求められる様々な撮影手技に対応するためにはケーブルのように可搬型センサの移動距離が限られている場合は困難な手技が存在した。例えば、同じ患者に対して要求された複数の検査を一度に実施する場合、撮影手技で求められる患者の姿勢体位が臥位と立位であった場合、臥位では可搬型センサは天板の下に設置することが必要となる。また、立位の場合では天板付近に設置されているスタンドに取り付けて撮影することが必要となる。近年は、このように複数の姿勢体位による撮影を１つのＸ線撮影室で行うことを目的としたMerged Room（マージドルーム）と呼ばれる撮影室の形態も普及している。 The portable sensor was initially supplied with power by connecting a power source and the portable sensor itself with a cable. However, in order to cope with various photographing techniques required in the photographing system, there is a difficult technique when the movement distance of the portable sensor such as a cable is limited. For example, when multiple tests requested for the same patient are performed at the same time, if the posture position of the patient required by the imaging procedure is in the prone position and the standing position, the portable sensor is It is necessary to install it below. Further, in the case of standing, it is necessary to shoot by attaching to a stand installed near the top board. In recent years, a form of an imaging room called a merged room, which aims to perform imaging with a plurality of postures and positions in one X-ray imaging room, has become widespread in recent years.

このような多種多様な撮影手技に対応するためには、ケーブルによって電力源と接続された形態のカセッテ式センサでは１つで賄いきれない場合が多いため、上述したように充電バッテリを装着して動作可能である可搬型センサが近年普及している。 In order to cope with such a wide variety of shooting techniques, a cassette type sensor connected to a power source by a cable often cannot be covered by one, so a charging battery is attached as described above. In recent years, portable sensors that can operate have become widespread.

可搬型センサに装着される充電バッテリとしては、ニッケル・カドミウム電池、ニッケル水素電池、リチウム・イオン電池等が使用される。但し、可搬型センサを使用することにより様々なメリットが生じるが、その一方でデメリットも存在する。可搬型センサの動作に必要な電力は充電バッテリのみで賄うため、充電バッテリの充電が切れてしまった時点で動作不可能となる。そのため、充電残量が少なくなっているにも関わらず撮影を行っていると思わぬタイミングで撮影がストップしてしまい、目的とする画像を取得することができず、且つ患者への無駄な被爆といった問題も生じる。 As the rechargeable battery to be mounted on the portable sensor, a nickel / cadmium battery, a nickel metal hydride battery, a lithium ion battery, or the like is used. However, using a portable sensor has various advantages, but there are also disadvantages. Since the electric power necessary for the operation of the portable sensor is provided only by the charging battery, the operation becomes impossible when the charging battery is completely discharged. For this reason, if shooting is performed even though the remaining charge is low, shooting stops at an unexpected timing, the target image cannot be acquired, and the patient is exposed to unnecessary exposure. Such a problem also arises.

これに対し、特許文献１には、センサユニットに充電バッテリとその充電バッテリに取りつけられた充電端子とを設け、センサユニットを移動型のテーブルに設置しておくことで検査と検査との間に生じる待機時間に充電する技術が開示されている。 On the other hand, in Patent Document 1, a charging battery and a charging terminal attached to the charging battery are provided in the sensor unit, and the sensor unit is installed on a movable table so that the inspection unit can be used between inspections. A technique for charging during the waiting time that occurs is disclosed.

また、次なる問題として、充電バッテリの経時的な劣化が挙げられる。充電バッテリは使用した時間に応じて消費電力が上昇し、一回の充電で使用可能な持続時間が短くなっていく。この劣化状況は充電バッテリを使用していても感覚的に分かる情報ではない。劣化した充電バッテリは使用持続時間が短くなるため、頻繁に充電が必要となり、撮影技師のワークフローが煩雑となる。また、上述した検査実施中に充電が切れてしまう危険性もより上がってしまう。 Further, as a next problem, deterioration of the charging battery with time is given. The power consumption of a rechargeable battery increases according to the time it is used, and the duration that can be used with a single charge decreases. This deterioration state is not information that can be perceived sensibly even when a rechargeable battery is used. A deteriorated rechargeable battery has a shorter duration of use, and therefore requires frequent charging, which complicates the workflow of the radiographer. In addition, there is a higher risk that the battery will be charged during the above-described inspection.

このような問題を解決する方法としては、充電バッテリを新しく取りかえることが必要となる。特許文献２には、複数の充電バッテリを使用している際に各充電バッテリの劣化の度合いを検出し、検査で実施予定の撮影回数に応じてどの充電バッテリを使用するべきかを決定し、ユーザに提示する技術が開示されている。 As a method for solving such a problem, it is necessary to replace the charging battery with a new one. Patent Document 2 detects the degree of deterioration of each charging battery when using a plurality of charging batteries, determines which charging battery should be used according to the number of shootings scheduled to be performed in the inspection, A technique presented to a user is disclosed.

しかしながら、充電バッテリには通常時の平均的な経時劣化以外にも劣化する要因が考えられる。仮に、使用している充電バッテリにいずれかの不具合が生じている場合は、平均よりも早いペースで劣化していくことも考えられる。また、場合によっては充電バッテリを装着している可搬型センサ側に不具合が生じることで充電バッテリの劣化を早めることも考えられる。 However, there are conceivable factors that cause deterioration in the rechargeable battery other than the average deterioration with time of normal times. If any problem occurs in the rechargeable battery being used, it may be deteriorated at a faster pace than the average. In some cases, it may be possible to accelerate the deterioration of the charging battery by causing a problem on the portable sensor side where the charging battery is mounted.

このような問題に対して、特許文献１に開示された技術では、劣化状況が判断できないため、仮に不具合が生じている充電バッテリであったとしても充電してしまい、劣化状況の悪化を加速させてしまう。また、特許文献２に開示された技術では、例え劣化度合いが他の充電バッテリよりも早く通知されたとしても、撮影回数が少ない検査においてその充電バッテリの使用が提示されるのみであり、根本的な解決とはならない問題が生じる。 With respect to such a problem, the technology disclosed in Patent Document 1 cannot determine the deterioration state, so even if it is a charged battery having a problem, it is charged, and the deterioration of the deterioration state is accelerated. End up. Further, in the technique disclosed in Patent Document 2, even if the degree of deterioration is notified earlier than other charging batteries, only the use of the charging battery is presented in an inspection with a small number of shootings. A problem that cannot be solved properly occurs.

不具合の疑いがある充電バッテリに対しては、販売会社又はサービス会社の点検が不可欠であり、場合によっては交換の必要が生じる。特に、中小規模の撮影施設等、使用されている可搬型センサと充電バッテリとのセット数が少ない施設においては、その中に不具合の疑いがある充電バッテリ等が含まれていることは非常に大きな問題となり、一刻も早い対応が必要となる。 For a charged battery that is suspected of malfunctioning, inspection by the sales company or service company is indispensable, and in some cases, replacement is required. In particular, in facilities where the number of used portable sensors and charging batteries is small, such as small and medium-sized photography facilities, it is very large that a charging battery that is suspected of malfunction is included in the facility. It becomes a problem and needs to be dealt with as soon as possible.

そこで、本発明の目的は、不具合の疑いがあるバッテリをそのまま使用してしまうことを防ぐことにある。 Therefore, an object of the present invention is to prevent the use of a battery that is suspected of malfunction.

以下、本発明を適用した好適な実施形態を、添付図面を参照しながら詳細に説明する。 DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments to which the invention is applied will be described in detail with reference to the accompanying drawings.

先ず、本発明の第１の実施形態について説明する。図１は、本発明の第１の実施形態に係る医用画像撮影システムの構成を示す図である。図１に示すように、第１の実施形態に係る医用画像撮影システムでは、充電バッテリ１０１、可搬型センサ１０２及び医用画像撮影装置１０３がネットワークを介して通信を行う。なお、医用画像撮影装置１０３は情報処理装置の適用例となる構成である。 First, a first embodiment of the present invention will be described. FIG. 1 is a diagram showing a configuration of a medical image photographing system according to the first embodiment of the present invention. As shown in FIG. 1, in the medical image capturing system according to the first embodiment, the charging battery 101, the portable sensor 102, and the medical image capturing apparatus 103 communicate via a network. The medical image photographing apparatus 103 has a configuration as an application example of the information processing apparatus.

先ず、充電バッテリ１０１の構成について説明する。充電バッテリ１０１内の送受信部１０４は、可搬型センサ１０２内の送受信部１０６と通信を行う構成であり、特にバッテリ情報を送信する。ここでバッテリ情報とは、充電バッテリ１０１を一意に識別可能であるシリアルナンバ、充電バッテリ１０１の製造メーカ及び充電バッテリ１０１の寸法等、充電バッテリ１０１特有の情報である。その他、バッテリ情報には、充電バッテリ１０１が充電された直近の日付情報（前回充電日時）や充電残量情報が含まれる。充電残量情報とは、最大充電量と現在の充電量との比で示される値である。なお、送受信部１０４は、組み込みの通信機器及びそれを制御するファームウェア等から構成される。充電情報管理部１０５は、主に充電バッテリ１０１における充電残量を計測したり、充電した日付情報（充電日時）を管理する。バッテリ情報は、送受信部１０４によって可搬型センサ１０２に対して送信される。なお、充電残量の計測は、主に充電バッテリ１０１が可搬型センサ１０２に取り付けられたタイミングで実施されるが、それ以外にも可搬型センサ１０２の電源が入れられたタイミング等で実施してもよく、計測のタイミングは特に限定されない。また、充電情報管理部１０５内のメモリ領域に充電残量情報を保持しておくことで、充電残量の計測直後でなくても後から送受信部１０４に対して充電残量情報を通知することも可能である。 First, the configuration of the rechargeable battery 101 will be described. The transmission / reception unit 104 in the rechargeable battery 101 is configured to communicate with the transmission / reception unit 106 in the portable sensor 102, and in particular transmits battery information. Here, the battery information is information unique to the charging battery 101, such as a serial number that can uniquely identify the charging battery 101, the manufacturer of the charging battery 101, and the dimensions of the charging battery 101. In addition, the battery information includes the most recent date information (previous charging date and time) when the charging battery 101 is charged and remaining charge information. The remaining charge information is a value indicated by the ratio between the maximum charge amount and the current charge amount. The transmission / reception unit 104 includes a built-in communication device and firmware for controlling the communication device. The charge information management unit 105 mainly measures the remaining charge amount in the rechargeable battery 101 and manages charged date information (charge date and time). The battery information is transmitted to the portable sensor 102 by the transmission / reception unit 104. The remaining charge is measured mainly at the timing when the rechargeable battery 101 is attached to the portable sensor 102, but at other times the portable sensor 102 is powered on. The timing of measurement is not particularly limited. Further, by holding the remaining charge information in the memory area in the charge information management unit 105, the remaining charge information is notified to the transmission / reception unit 104 later even if not immediately after the remaining charge is measured. Is also possible.

次に、可搬型センサ１０２の構成について説明する。可搬型センサ１０２内の送受信部１０６は、充電バッテリ１０１内の送受信部１０４及び医用画像撮影装置１０３内の送受信部１０９の両方と通信を行う構成であり、主に充電バッテリ毎のバッテリ情報や検査実施情報の送受信を行う。なお、送受信部１０６は、組み込みの通信機器及びそれを制御するファームウェア等から構成される。画像データ管理部１０７は、可搬型センサ１０２によって撮影された画像データを保存及び管理する。可搬型センサ１０２によって撮影された画像データは、画像データ管理部１０７において補正処理が施され、送受信部１０６を介して医用画像撮影装置１０３に対して送信される。このとき、帯域中のノイズによって無線ネットワークがうまく繋がらず、画像データの送信を失敗するケースがある。そのため、画像データ管理部１０７は、画像データ送信後も次回の撮影が行われるまでは画像データを保存しておき、再送要求を受信した際に確実に再送を行うようにする。バッテリ情報取得部１０８は、可搬型センサ１０２に取り付けられている充電バッテリ１０１の充電残量情報を取得し、保持する。即ち、バッテリ情報取得部１０８は、可搬型センサ１０２の電源が入れられると、送受信部１０６に対してバッテリ情報の通知要求を行うよう指示する。但し、バッテリ情報の通知要求を行うタイミングはこれに限らない、例えば医用画像撮影装置１０３からバッテリ情報の通知が要求された場合等、外部からの指示に応じてバッテリ情報の通知要求を行ってもよい。バッテリ情報取得部１０８はバッテリ情報を受信すると、内部のメモリ領域に保存する。 Next, the configuration of the portable sensor 102 will be described. The transmission / reception unit 106 in the portable sensor 102 is configured to communicate with both the transmission / reception unit 104 in the charging battery 101 and the transmission / reception unit 109 in the medical image photographing apparatus 103, and mainly includes battery information and inspection for each charging battery. Send and receive implementation information. The transmission / reception unit 106 includes a built-in communication device and firmware for controlling the communication device. The image data management unit 107 stores and manages image data captured by the portable sensor 102. Image data captured by the portable sensor 102 is subjected to correction processing in the image data management unit 107 and transmitted to the medical image capturing apparatus 103 via the transmission / reception unit 106. At this time, there are cases where the wireless network is not connected well due to noise in the band, and transmission of image data fails. Therefore, the image data management unit 107 stores the image data until the next shooting is performed after the image data is transmitted, and reliably performs the retransmission when the retransmission request is received. The battery information acquisition unit 108 acquires and holds the remaining charge information of the rechargeable battery 101 attached to the portable sensor 102. That is, when the portable sensor 102 is turned on, the battery information acquisition unit 108 instructs the transmission / reception unit 106 to make a battery information notification request. However, the timing at which the battery information notification request is made is not limited to this. For example, when the battery information notification is requested from the medical imaging apparatus 103, the battery information notification request may be made in response to an external instruction. Good. When the battery information acquisition unit 108 receives the battery information, the battery information acquisition unit 108 stores it in the internal memory area.

次に、医用画像撮影装置１０３の構成について説明する。医用画像撮影装置１０３内の送受信部１０９は、可搬型センサ１０２内の送受信部１０６と通信を行う構成であり、主に充電バッテリ毎のバッテリ情報や検査実施情報を受信したり、各情報の通知要求を送信したりする。なお、送受信部１０９は、イーサネット（登録商標）等の各種ネットワークにて実現される。画像表示部１１６は、可搬型センサ１０２によって取得された画像データが表示されるディスプレイ機器である。その他にも、画像表示部１１６は、医用画像撮影装置１０３に対してオペレーションするための制御用グラフィックユーザインタフェース（以下、ＧＵＩと称す）を表示する。オペレータによるＧＵＩ上での操作によって、画像データ取得後の検像、画像処理及び外部への画像データ送信等、様々な処理が可能となる。バッテリ情報管理部１１０は、バッテリ情報テーブル１１２を使用してバッテリ情報を一元管理する。 Next, the configuration of the medical image photographing apparatus 103 will be described. The transmission / reception unit 109 in the medical image capturing apparatus 103 is configured to communicate with the transmission / reception unit 106 in the portable sensor 102. The transmission / reception unit 109 mainly receives battery information and examination execution information for each charged battery, and notifies each information. Or send a request. The transmission / reception unit 109 is realized by various networks such as Ethernet (registered trademark). The image display unit 116 is a display device on which image data acquired by the portable sensor 102 is displayed. In addition, the image display unit 116 displays a control graphic user interface (hereinafter referred to as GUI) for operating the medical image capturing apparatus 103. Various operations such as image inspection after image data acquisition, image processing, and image data transmission to the outside can be performed by operations on the GUI by the operator. The battery information management unit 110 centrally manages battery information using the battery information table 112.

図２は、バッテリ情報テーブル１１２の例を示す図である。図２に示すように、バッテリ情報テーブル１１２には、各充電バッテリのシリアルナンバ、充電残量情報及び製造メーカ等のバッテリ情報が保存されている。その他、バッテリ情報テーブル１１２には、充電バッテリ１０１の劣化状態又は不具合を判断するために、平均電源オン時間、前回充電日時、前回充電時からの総電源オン時間、使用開始時からの総電源オン時間、及び、充電回数が保持されている。平均電源オン時間とは、充電してから次の充電が必要になるまでの総電源オン時間の平均である。なお、その他の情報をバッテリ情報テーブル１１２に保存することも可能である。また、本実施形態においては、充電バッテリをシリアルナンバで管理している。これにより、施設内で使用されている充電バッテリ全てを一意に特定することが可能である。なお、バッテリ情報テーブル１１２で管理される各情報は、第１の管理手段において管理されるバッテリ情報に係る情報の一例である。 FIG. 2 is a diagram illustrating an example of the battery information table 112. As shown in FIG. 2, the battery information table 112 stores the serial number of each charging battery, remaining charge information, and battery information such as the manufacturer. In addition, the battery information table 112 includes an average power-on time, a previous charge date and time, a total power-on time from the previous charge, and a total power-on from the start of use in order to determine the deterioration state or malfunction of the rechargeable battery 101. Time and the number of times of charging are held. The average power-on time is an average of the total power-on time from charging until the next charging becomes necessary. Other information can be stored in the battery information table 112. In this embodiment, the rechargeable battery is managed with a serial number. Thereby, it is possible to uniquely specify all the rechargeable batteries used in the facility. Each piece of information managed by the battery information table 112 is an example of information related to battery information managed by the first management unit.

電源オン時間カウント部１１１は、バッテリ情報管理部１１０より可搬型センサ１０２の電源オン／オフ切り替えの通知、及び、その際に装着されていた充電バッテリ１０１のバッテリ情報を入力する。そして電源オン時間カウント部１１１は、可搬型センサ１０２が電源オン状態となった時間をカウントする。また、電源オン時間カウント部１１１は、充電バッテリ１０１の電源がオフになったタイミングでバッテリ情報管理部１１０に対してカウントした時間を通知する。検査情報管理部１１４は、医用画像撮影装置１０３における検査実施情報を、検査情報テーブル１１５を使用して一元管理する。図３は検査情報テーブル１１５の例を示す図である。図３に示すように、検査情報テーブル１１５には、使用された充電バッテリ１０１のシリアルナンバ、検査を一意に特定するための検査Ｎｏ、検査実施中に可搬型センサ１０２を電源オンにしていた合計時間（電源オン時間）、及び、検査で実施された撮影手技が含められる。なお、その他の情報が検査情報テーブル１１５に保存されてもよい。 The power-on time counting unit 111 receives a notification of power on / off switching of the portable sensor 102 from the battery information management unit 110 and the battery information of the rechargeable battery 101 attached at that time. The power-on time counting unit 111 counts the time when the portable sensor 102 is in a power-on state. The power-on time counting unit 111 notifies the battery information management unit 110 of the counted time at the timing when the power of the charging battery 101 is turned off. The examination information management unit 114 centrally manages examination execution information in the medical image photographing apparatus 103 using the examination information table 115. FIG. 3 is a diagram illustrating an example of the inspection information table 115. As shown in FIG. 3, the inspection information table 115 includes the serial number of the used rechargeable battery 101, the inspection number for uniquely identifying the inspection, and the total of the portable sensor 102 that was turned on during the inspection. Time (power-on time) and the imaging procedure performed in the examination are included. Other information may be stored in the inspection information table 115.

バッテリ不具合判断部１１３は、バッテリ情報管理部１１０及び検査情報管理部１１４からバッテリ情報及び検査実施情報を取得し、充電バッテリ１０１に不具合の疑いがないかを調査する。充電バッテリ１０１に不具合の疑いがある場合、画像表示部１１６は警告表示を行う。以上のように、本実施形態においては、充電バッテリ１０１に関して不具合の調査が随時実施され、充電バッテリ１０１に不具合の疑いがある場合、速やかにオペレータに対して通知される。 The battery failure determination unit 113 acquires battery information and inspection execution information from the battery information management unit 110 and the inspection information management unit 114, and investigates whether the charged battery 101 is suspected of a failure. When the charged battery 101 is suspected of malfunction, the image display unit 116 displays a warning. As described above, in the present embodiment, a trouble investigation regarding the rechargeable battery 101 is performed at any time, and when there is a suspicion of a trouble in the rechargeable battery 101, the operator is notified immediately.

図４は、本実施形態に係る医用画像撮影システムを用いた検査方法の例を示す図である。図４に示すように、Ｘ線撮影の被験者を臥位で撮影する場合、被験者は天板４０８に横たわった状態で撮影される。可搬型センサ１０２は、充電バッテリ１０１が取り付けられることで動作可能となる。なお、図４では、可搬型センサ１０２と充電バッテリ１０１とを区別するために線で繋いだ状態で示しているが、実際は、充電バッテリ１０１は可搬型センサ１０２の内部に取り付けられている。可搬型センサ１０２はワイヤレスステーション４０３と無線ネットワークとを使用して通信を行う。臥位で撮影を行う場合は、可搬型センサ１０２は一般的に天板４０８の内部に設置されたり、天板４０８と被験者との間に置かれる。一方で、ワイヤレスステーション４０３は、Ｘ線発生装置４０４及び医用画像撮影装置１０３と接続され、Ｘ線撮影に関する情報をやり取りする。Ｘ線発生装置４０４にはＸ線管球４０５及び照射スイッチ４０６が接続されている。照射スイッチ４０６が押下されると、Ｘ線発生装置４０４は、Ｘ線管球４０５にＸ線を発射するよう要求することにより、Ｘ線管球４０５からＸ線が照射される。その結果、可搬型センサ１０２によって画像データが生成され、無線ネットワークを介して医用画像撮影装置１０３に送信される。医用画像撮影装置１０３は、可搬型センサ１０２から送信された画像データを画像表示部１１６に表示する。 FIG. 4 is a diagram illustrating an example of an inspection method using the medical image photographing system according to the present embodiment. As shown in FIG. 4, when an X-ray imaging subject is photographed in a supine position, the subject is photographed while lying on the top board 408. The portable sensor 102 can be operated by attaching the rechargeable battery 101. In FIG. 4, the portable sensor 102 and the rechargeable battery 101 are illustrated as being connected by a line in order to distinguish them, but in reality, the rechargeable battery 101 is attached inside the portable sensor 102. The portable sensor 102 performs communication using the wireless station 403 and a wireless network. When photographing in the prone position, the portable sensor 102 is generally installed inside the top board 408 or placed between the top board 408 and the subject. On the other hand, the wireless station 403 is connected to the X-ray generation apparatus 404 and the medical image imaging apparatus 103 and exchanges information related to X-ray imaging. An X-ray tube 405 and an irradiation switch 406 are connected to the X-ray generator 404. When the irradiation switch 406 is pressed, the X-ray generator 404 irradiates the X-ray tube 405 with X-rays by requesting the X-ray tube 405 to emit X-rays. As a result, image data is generated by the portable sensor 102 and transmitted to the medical image capturing apparatus 103 via the wireless network. The medical image photographing apparatus 103 displays the image data transmitted from the portable sensor 102 on the image display unit 116.

図５は、本実施形態に係る医用画像撮影システムを用いた検査方法の他の例を示す図である。なお、図５において、図４に示した構成と同一の構成は、図４と同一の符合を付してある。図５に示す構成では、Ｘ線撮影の被験者を立位で撮影する場合、被験者は可搬型センサ１０２が設置された立位スタンド５０８とＸ線管球４０５との間に立った状態で撮影される。但し、この場合、図５に示すようにＸ線管球４０５は正しく立位スタンドの正面から照射できるようメーカ連動によって照射方向が変更される。 FIG. 5 is a diagram illustrating another example of the inspection method using the medical image photographing system according to the present embodiment. In FIG. 5, the same components as those shown in FIG. 4 are denoted by the same reference numerals as those in FIG. In the configuration shown in FIG. 5, when an X-ray subject is photographed in a standing position, the subject is photographed while standing between the standing stand 508 provided with the portable sensor 102 and the X-ray tube 405. The However, in this case, as shown in FIG. 5, the irradiation direction of the X-ray tube 405 is changed in conjunction with the manufacturer so that the X-ray tube 405 can be correctly irradiated from the front of the stand.

次に、図６に示すフローチャートを参照しながら、第１の実施形態に係る医用画像撮影システムの処理について説明する。ここでは、医用画像撮影システムを起動させてから検査が終了するまでの処理について説明する。 Next, processing of the medical image photographing system according to the first embodiment will be described with reference to the flowchart shown in FIG. Here, processing from when the medical image photographing system is activated until the examination is completed will be described.

ステップＳ６０１において、充電バッテリ１０１が可搬型センサ１０２に取り付けられることにより、充電バッテリ１０１の充電情報管理部１０５は充電残量を計測する。ステップＳ６０２において、充電残量管理部１０５は計測した充電残量を示す充電残量情報を保持する。ステップＳ６１１において、充電バッテリ１０１が取り付けられた可搬型センサ１０２は、オペレータによって電源が入れられる。ステップＳ６１２において、可搬型センサ１０２のバッテリ情報取得部１０８は、バッテリ情報の通知を充電バッテリ１０１に対して要求する。ステップＳ６０３において、充電バッテリ１０１の充電情報管理部１０５は、可搬型センサ１０２からバッテリ情報の通知要求を受け付ける。ステップＳ６０４において、充電情報管理部１０５は、可搬型センサ１０２に対してバッテリ情報を送信する。ステップＳ６１３において、可搬型センサ１０２は、充電バッテリ１０１からバッテリ情報を受信する。ステップＳ６１４において、可搬型センサ１０２は、バッテリ情報に含まれる充電バッテリ１０１のシリアルナンバ及び前回充電日時を医用画像撮影装置１０３に対して送信する。ステップＳ６２１において、医用画像撮影装置１０３は、可搬型センサ１０２から充電バッテリ１０１のシリアルナンバ及び前回充電日時を受信する。 In step S601, when the charging battery 101 is attached to the portable sensor 102, the charging information management unit 105 of the charging battery 101 measures the remaining charge. In step S602, the remaining charge management unit 105 stores remaining charge information indicating the measured remaining charge. In step S611, the portable sensor 102 to which the rechargeable battery 101 is attached is turned on by the operator. In step S612, the battery information acquisition unit 108 of the portable sensor 102 requests the charging battery 101 to notify the battery information. In step S 603, the charging information management unit 105 of the charging battery 101 receives a battery information notification request from the portable sensor 102. In step S 604, the charging information management unit 105 transmits battery information to the portable sensor 102. In step S 613, the portable sensor 102 receives battery information from the rechargeable battery 101. In step S 614, the portable sensor 102 transmits the serial number of the charging battery 101 and the previous charging date / time included in the battery information to the medical image photographing apparatus 103. In step S 621, the medical imaging apparatus 103 receives the serial number of the charging battery 101 and the previous charging date / time from the portable sensor 102.

ステップＳ６２２において、電源オン時間カウント部１１１はカウントを開始する。ステップＳ６２３において、バッテリ情報管理部１１０は、充電バッテリ１０１から取得された前回充電日時と、バッテリ情報テーブル１１２内において当該シリアルナンバに対応付けて記録されている前回充電日時とを比較する。これにより、バッテリ情報管理部１１０は、バッテリ情報テーブル１１２内において最新の前回充電日時に更新されているか否かを判定する。充電バッテリ１０１から取得された前回充電日時と、バッテリ情報テーブル１１２内に記録されている前回充電日時とが同じである場合、バッテリ情報テーブル１１２内において最新の前回充電日時に更新されているものとして、処理はステップＳ６２５に移行する。一方、充電バッテリ１０１から取得された前回充電日時と、バッテリ情報テーブル１１２内に記録されている前回充電日時とが異なる場合、バッテリ情報テーブル１１２内において最新の前回充電日時に更新されていないものとして、処理はステップＳ６２４に移行する。ステップＳ６２４において、バッテリ情報管理部１１０は、バッテリ情報テーブル１１２内の前回充電日時を、充電バッテリ１０１から取得された前回充電日時に更新する。 In step S622, the power-on time counting unit 111 starts counting. In step S623, the battery information management unit 110 compares the previous charging date and time acquired from the charging battery 101 with the previous charging date and time recorded in association with the serial number in the battery information table 112. Thereby, the battery information management unit 110 determines whether or not the battery information table 112 has been updated to the latest previous charging date and time. When the previous charging date and time acquired from the charging battery 101 and the previous charging date and time recorded in the battery information table 112 are the same, the battery information table 112 is updated to the latest previous charging date and time. The process moves to step S625. On the other hand, if the previous charging date and time acquired from the charging battery 101 and the previous charging date and time recorded in the battery information table 112 are different, it is assumed that the battery information table 112 has not been updated to the latest previous charging date and time. The processing moves to step S624. In step S624, the battery information management unit 110 updates the previous charging date and time in the battery information table 112 to the previous charging date and time acquired from the charging battery 101.

ところで、可搬型センサ１０２は、ステップＳ６１４において充電バッテリ１０１のシリアルナンバ及び前回充電日時を送信した後、ステップＳ６１５において充電バッテリ１０１のシリアルナンバ及び充電残量情報を送信する。ステップＳ６２５において、医用画像撮影装置１０３は、可搬型センサ１０２から充電バッテリ１０１のシリアルナンバ及び充電残量情報を受信する。ステップＳ６２６において、バッテリ情報テーブル１１２において当該シリアルナンバに対応付けて記録される充電残量情報を、ステップＳ６２５で受信した充電残量情報で更新する。 By the way, the portable sensor 102 transmits the serial number of the charging battery 101 and the previous charging date and time in step S614, and then transmits the serial number and remaining charge information of the charging battery 101 in step S615. In step S625, the medical image photographing apparatus 103 receives the serial number and remaining charge information of the charging battery 101 from the portable sensor 102. In step S626, the remaining charge information recorded in association with the serial number in the battery information table 112 is updated with the remaining charge information received in step S625.

ステップＳ６２７において、バッテリ情報管理部１１０は、更新後の充電残量情報で示される充電残量が、所定の値未満であるか否かを判定する。充電残量が所定の値未満である場合、処理はステップＳ６２８に移行する。一方、充電残量が所定の値以上である場合、ステップＳ６２８をスキップして処理はステップＳ６２９に移行する。ステップＳ６２８において、画像表示部１１６は、充電バッテリ１０１の充電又は交換を促す警告を表示する。なお、ここで警告表示を行うか否かを判定するための上記所定の値（最大充電量に対する所定の割合）として、任意に設定された値が用いられる。 In step S627, the battery information management unit 110 determines whether or not the remaining charge amount indicated by the updated remaining charge information is less than a predetermined value. If the remaining charge is less than the predetermined value, the process proceeds to step S628. On the other hand, if the remaining charge is equal to or greater than the predetermined value, step S628 is skipped and the process proceeds to step S629. In step S628, the image display unit 116 displays a warning prompting charging or replacement of the rechargeable battery 101. Here, an arbitrarily set value is used as the predetermined value (predetermined ratio with respect to the maximum charge amount) for determining whether or not to perform warning display.

ステップＳ６２９において、バッテリ不具合判断部１１３は、バッテリ情報テーブル１１２及び検査情報テーブル１１５を参照することにより、充電バッテリ１０１に不具合が生じているかを調査する。ここで、充電バッテリ１０１に不具合が生じているかを調査する処理について説明する。充電バッテリ１０１の不具合の調査は、劣化状態を用いた調査と充電残量を用いた調査との２つに区別される。先ず、劣化状態を用いた調査について説明する。バッテリ不具合判断部１１３は、バッテリ情報テーブル１１２から充電バッテリ１０１の「総合電源オン時間ｍ」及び「充電回数ｎ」を取得する。次にバッテリ不具合判断部１１３は、不具合度数ａとしてａ＝ｍ×ｎの式より不具合度数（充電バッテリ１０１の劣化状態に関する値）を算出する。バッテリ不具合判断部１１３は、算出した不具合度数ａと、これまで劣化状態が危険となった充電バッテリ１０１で求められた不具合度数の平均値ａ´とを比較する。ａの値がａ´未満である場合、バッテリ不具合判断部１１３は何らかの不具合によって充電バッテリ１０１が急速に劣化したと判断する。なお、ステップＳ６２９は、第１の調査手段の処理例である。 In step S629, the battery failure determination unit 113 checks whether there is a failure in the rechargeable battery 101 by referring to the battery information table 112 and the inspection information table 115. Here, a process for investigating whether or not a failure has occurred in the rechargeable battery 101 will be described. The investigation of the failure of the rechargeable battery 101 can be classified into two types: an investigation using the deterioration state and an investigation using the remaining charge amount. First, the investigation using the deterioration state will be described. The battery failure determination unit 113 acquires the “total power on time m” and the “number of times of charging n” of the charging battery 101 from the battery information table 112. Next, the battery failure determination unit 113 calculates the failure frequency (a value related to the deterioration state of the rechargeable battery 101) from the equation a = m × n as the failure frequency a. The battery failure determination unit 113 compares the calculated failure frequency a with the average value a ′ of the failure frequencies obtained for the rechargeable battery 101 whose deterioration state has been dangerous. When the value of a is less than a ′, the battery failure determination unit 113 determines that the charging battery 101 has rapidly deteriorated due to some failure. Step S629 is a processing example of the first investigation unit.

次に、充電残量を用いた調査について説明する。充電バッテリ１０１より充電残量情報が通知されてきた場合、バッテリ不具合判断部１１３は、充電残量が所定の値より低くなった充電バッテリ１０１について、バッテリ情報テーブル１１２から、対応する充電バッテリ１０１の「平均電源オン時間Ｍ」と「前回充電時からの総電源オン時間Ｓ」とを取得する。次に、バッテリ不具合判断部１１３は、ｂ＝Ｍ／Ｓの式より不具合度数（充電バッテリ１０１の充電残量に関する値）ｂを算出する。バッテリ不具合判断部１１３は、算出した不具合度数ｂと、これまで劣化状態が危険となった充電バッテリ１０１で求められた不具合度数の平均値ｂ´とを比較する。その結果、ｂの値がｂ´よりも大きい場合、バッテリ不具合判断部１１３は何らかの不具合によって充電バッテリ１０１が急速に劣化したと判断する。 Next, the investigation using the remaining charge will be described. When the remaining charge information is notified from the rechargeable battery 101, the battery failure determination unit 113 determines the corresponding rechargeable battery 101 from the battery information table 112 for the rechargeable battery 101 whose remaining charge is lower than a predetermined value. “Average power on time M” and “total power on time S from previous charging” are acquired. Next, the battery failure determination unit 113 calculates the failure frequency (value relating to the remaining charge of the rechargeable battery 101) b from the equation b = M / S. The battery failure determination unit 113 compares the calculated failure frequency b with the average value b ′ of the failure frequencies obtained for the rechargeable battery 101 whose deterioration state has been dangerous. As a result, when the value of b is larger than b ′, the battery malfunction determination unit 113 determines that the charging battery 101 has rapidly deteriorated due to some malfunction.

調査の結果、充電バッテリ１０１に不具合が生じている場合、処理はステップＳ６３１に移行する。一方、充電バッテリ１０１に不具合が生じていない場合、ステップＳ６３１をスキップして処理はステップＳ６３２に移行する。ステップＳ６３１において、画像表示部１１６は、充電バッテリ１０１に不具合が生じていることを警告する画面を表示する。 As a result of the investigation, if a problem has occurred in the rechargeable battery 101, the process proceeds to step S631. On the other hand, if there is no malfunction in the rechargeable battery 101, step S631 is skipped and the process proceeds to step S632. In step S 631, the image display unit 116 displays a screen that warns that a problem has occurred in the rechargeable battery 101.

ステップＳ６３２において、医用画像撮影装置１０３は、検査開始の指示が入力されることにより、検査を開始するための処理を行う。ステップＳ６３３において、医用画像撮影装置１０３は、Ｘ線撮影を制御する。ステップＳ６３４において、医用画像撮影装置１０３は、検査終了の指示が入力されることにより、検査を終了するための処理を行う。ステップＳ６３５において、医用画像撮影装置１０３の検査情報管理部１１４は、当該検査で実際に使用された充電バッテリ１０１のシリアルナンバ、検査Ｎｏ、検査中の電源オン時間、実施した撮影手技等の情報で検査情報テーブル１１５を更新する。検査情報テーブル１１５が更新された後、処理はステップＳ６２５に戻り、再び次の検査へ向けて同様の処理が行われる。 In step S632, the medical image photographing apparatus 103 performs a process for starting an examination when an instruction to start the examination is input. In step S633, the medical image capturing apparatus 103 controls X-ray imaging. In step S634, the medical image photographing apparatus 103 performs a process for ending the examination when an instruction to end the examination is input. In step S635, the examination information management unit 114 of the medical imaging apparatus 103 uses information such as the serial number of the charging battery 101 actually used in the examination, the examination number, the power-on time during the examination, and the imaging technique performed. The inspection information table 115 is updated. After the examination information table 115 is updated, the process returns to step S625, and the same process is performed again for the next examination.

次に、本発明の第２の実施形態について説明する。図７は、本発明の第２の実施形態に係る医用画像撮影システムの構成を示す図である。なお、図７において、図１と同様の構成については、図１と同じ符号が付してある。 Next, a second embodiment of the present invention will be described. FIG. 7 is a diagram showing a configuration of a medical image photographing system according to the second embodiment of the present invention. In FIG. 7, the same components as those in FIG. 1 are denoted by the same reference numerals as those in FIG.

可搬型センサ７０２のセンサ稼動情報管理部７０４は、可搬型センサ７０２のセンサ稼動情報や撮影実施情報を保存して管理する。ここでセンサ稼動情報とは、可搬型センサ７０２の電源が入れられた時刻及び電源が切られた時刻や、可搬型センサ７０２のステータス毎の継続時間（例えば、照射可能ステータスの継続時間が３時間）等を示す情報である。撮影実施情報とは、撮影時の管電圧、管電流、照射時間、使用された可搬型センサ７０２、及び、使用された充電バッテリ１０１等を示す情報である。医用画像撮影装置７０３のセンサ情報管理部７０６は、使用された可搬型センサ７０２に関する情報を、センサ情報テーブル７０７を使用して一元管理する。 The sensor operation information management unit 704 of the portable sensor 702 stores and manages the sensor operation information and shooting execution information of the portable sensor 702. Here, the sensor operation information refers to the time when the portable sensor 702 is turned on and the time when the power is turned off, and the duration of each status of the portable sensor 702 (for example, the duration of the irradiable status is 3 hours). ) Etc. The shooting execution information is information indicating the tube voltage, tube current, irradiation time at the time of shooting, the used portable sensor 702, the used charging battery 101, and the like. The sensor information management unit 706 of the medical image photographing apparatus 703 centrally manages information on the used portable sensor 702 using the sensor information table 707.

図８は、センサ情報テーブル７０７の例を示す図である。センサ情報テーブル７０７には、可搬型センサ７０２を一意に特定するためのシリアルナンバ、装着された充電バッテリ１０１に不具合が生じた回数である不具合カウント数、不具合カウント数が前回足された日時（前回不具合カウント日時）、及び、不具合カウント数を加算した時間間隔の平均値である平均不具合カウント時間を含む。なお、その他の情報がセンサ情報テーブル７０７に保存されていてもよい。センサ・バッテリ不具合判断部７０５は、バッテリ情報テーブル１１２、センサ情報テーブル７０７及び検査情報テーブル１１５を参照することにより、登録されている各充電バッテリ又は各可搬型センサに不具合の疑いがないかを調査する。不具合の疑いがある充電バッテリ１０１又は可搬型センサ７０２が存在する場合、画像表示部１１６は警告表示を行う。以上のように、本実施形態においては、充電バッテリ１０１及び可搬型センサ７０２の不具合の判断が随時実施され、不具合の疑いがある場合には、速やかにオペレータに対して通知される。なお、センサ情報テーブル７０７において管理される各情報は、第２の管理手段において管理される可搬型センサに係る情報の一例である。 FIG. 8 is a diagram illustrating an example of the sensor information table 707. The sensor information table 707 includes a serial number for uniquely identifying the portable sensor 702, a failure count that is the number of times that a failure has occurred in the attached rechargeable battery 101, and the date and time when the failure count was previously added (previous Failure count date and time) and an average failure count time which is an average value of time intervals obtained by adding the failure count numbers. Other information may be stored in the sensor information table 707. The sensor / battery failure determination unit 705 refers to the battery information table 112, the sensor information table 707, and the inspection information table 115 to investigate whether there is a suspicion of failure in each registered rechargeable battery or each portable sensor. To do. When there is a rechargeable battery 101 or a portable sensor 702 that is suspected of malfunction, the image display unit 116 displays a warning. As described above, in the present embodiment, the determination of the malfunction of the rechargeable battery 101 and the portable sensor 702 is performed at any time, and if there is a suspicion of the malfunction, the operator is promptly notified. Each piece of information managed in the sensor information table 707 is an example of information related to a portable sensor managed by the second management unit.

次に、図９に示すフローチャートを参照しながら、第２の実施形態に係る医用画像撮影システムの処理について説明する。但し、図９におけるステップＳ６０１〜Ｓ６０４、ステップＳ６１１〜Ｓ６１５、ステップＳ６２１〜Ｓ６３５は、図６に示す同一符号の処理と同様であるため、それらについての説明は省略する。 Next, processing of the medical image capturing system according to the second embodiment will be described with reference to the flowchart shown in FIG. However, steps S601 to S604, steps S611 to S615, and steps S621 to S635 in FIG. 9 are the same as the processes with the same reference numerals shown in FIG.

ステップＳ９０１において、センサ・バッテリ不具合判断部７０５は、センサ情報テーブル７０７及び検査情報テーブル１１５を参照し、可搬型センサ７０２に不具合が生じていないかを調査する。以下、可搬型センサ７０２の不具合の調査方法について説明する。 In step S 901, the sensor / battery failure determination unit 705 refers to the sensor information table 707 and the inspection information table 115 and investigates whether a failure has occurred in the portable sensor 702. Hereinafter, a method for investigating a defect of the portable sensor 702 will be described.

可搬型センサ７０２に関しては、センサ情報テーブル７０７にて検査毎に使用された可搬型センサ７０２と充電バッテリ１０１との組み合わせが検索可能となっている。センサ情報テーブル７０７において、劣化状態が危険と判断され、且つ不具合による劣化と判定された充電バッテリを装着した履歴がある可搬型センサには不具合カウント数が１足される。また、平均電源オン時間が他の充電バッテリと比較して短くなっている充電バッテリを装着した履歴がある可搬型センサには不具合カウント数が１足される。その結果、センサ・バッテリ不具合判断部７０５は、不具合カウント数が所定の値を超え、且つ平均不具合カウント時間が所定の値より低くなった可搬型センサ７０２について何らかの不具合が発生していると判断する。なお、ステップＳ９０１は、第２の調査手段の処理例である。 With respect to the portable sensor 702, a combination of the portable sensor 702 and the rechargeable battery 101 used for each inspection can be searched in the sensor information table 707. In the sensor information table 707, the failure count is incremented by one for a portable sensor having a history of attaching a rechargeable battery in which the deterioration state is determined to be dangerous and the deterioration due to the failure is determined. In addition, the malfunction count is incremented by one for a portable sensor having a history of attaching a charging battery whose average power-on time is shorter than that of other charging batteries. As a result, the sensor / battery failure determination unit 705 determines that some failure has occurred in the portable sensor 702 in which the failure count number exceeds a predetermined value and the average failure count time is lower than the predetermined value. . Step S901 is a processing example of the second investigation means.

ステップＳ９０２において、センサ・バッテリ不具合判断部７０５は、調査の結果、可搬型センサ７０２に不具合が生じているか否かを判定する。可搬型センサ７０２に不具合が生じている場合、処理はステップＳ９０３に移行する。一方、可搬型センサ７０２に不具合が生じていない場合、ステップＳ９０３をスキップして処理はステップＳ６３２に移行する。ステップＳ９０３において、画像表示部１１６は、サービスマンによる可搬型センサ７０２の点検を受けることを促す警告表示を行う。ステップＳ６３２〜Ｓ６３５において、第１の実施形態と同様の検査処理と検査情報テーブル１１５の更新処理が行われる。ステップＳ９０５において、センサ情報管理部７０６は、センサ情報テーブル７０７を更新する。センサ情報テーブル７０７が更新された後、処理はステップＳ６２５に戻り、再び次の検査へ向けて同様の処理が行われる。 In step S902, the sensor / battery failure determination unit 705 determines whether or not the portable sensor 702 has a failure as a result of the investigation. If there is a problem with the portable sensor 702, the process proceeds to step S903. On the other hand, if there is no problem with the portable sensor 702, step S903 is skipped and the process proceeds to step S632. In step S 903, the image display unit 116 performs a warning display that prompts the service person to check the portable sensor 702. In steps S632 to S635, the same inspection process as in the first embodiment and the update process of the inspection information table 115 are performed. In step S905, the sensor information management unit 706 updates the sensor information table 707. After the sensor information table 707 is updated, the process returns to step S625, and the same process is performed again for the next inspection.

次に、本発明の第３の実施形態について説明する。第３の実施形態に係る医用画像撮影システムは、第２の実施形態に係る医用画像撮影システムの構成とは、図７の１０１〜１１２、１１４、１１５、７０５〜７０７の構成が医用画像撮影装置７０３とは異なる装置上に構成される点に違いがある。また、バッテリ情報テーブル１１２には、第１及び第２の実施形態で説明した情報の他に、充電バッテリ１０１毎の販売会社の所在地が保存される。センサ情報テーブル７０７には、第１及び第２の実施形態で説明した情報の他に、可搬型センサ７０２毎の販売会社の所在地が保存される。充電バッテリ１０１毎の販売会社の所在地を管理する処理は、第３の管理手段の処理例であり、可搬型センサ７０２毎の販売会社の所在地を管理する処理は、第４の管理手段の処理例である。 Next, a third embodiment of the present invention will be described.

In FIG. 10, the charging battery 101 and the portable sensor 702 have the same configuration as the charging battery 101 and the portable sensor 702 shown in FIG. The medical image photographing apparatus 1001 and the server system 1002 each include the transmission / reception unit 109 and the image display unit 116 shown in FIG.
