Description

Medical Image Archiving & Management System

The present invention improves the work of storing the patient's photographing film in the past when storing the patient's photographing image medical information to convert the digital form of the information directly to the computer without the film process and save the film at the time of photography The present invention relates to a medical image storage management system that makes a pleasant environment in a hospital by preventing waste of original storage space. And because the obtained data is recorded and managed in a differentiated database, all image data is stored in a computer, so it is easy to store and prevents the loss or damage of data unlike the case of storing in the form of a conventional film. In addition, through the high-speed communication network, it is possible to read the medical information of the patient quickly and remotely anytime, anywhere, and to manage the opinions and prescriptions of the doctors remotely, thus expanding the medical field of the medical practitioner and quickly searching the data such as clinical records. You can quickly analyze and analyze it.

Although some of the existing imaging systems are being used by each medical institution, they are not compatible with the medical information computer network, so they are used separately and are incompatible. However, in the present invention, it is possible to increase the efficiency of the entire treatment system by tying these overlapping systems together.

In addition, in order to reduce the vast amount of image images, the medical image image file is compressed so that the image may be damaged due to the compression process of the file. However, in the present invention, in order to secure this point, in the method of storing the medical image image file, a large amount of the medical image image obtained in the medical examination of the patient is excluded, and the compressed portion that causes image loss is excluded. It is classified systematically into the data storage server. After a certain period of time, the files are backed up to the data backup unit and stored in an auxiliary storage medium such as an optical disc or CD-ROM. In this way, when the doctor later requests the medical data for the inquiry of the patient's past medical history or the clinical and research statistics, the data of the desired item can be connected to the data storage server from the data backup department so that the data can be retrieved quickly. Analyzing past medical records can improve the effectiveness of medical care.

The present invention is to more efficiently process the medical information obtained from the various stages of inspection in the existing medical system, reducing the cost of the film state to reduce the cost of expensive medical film purchase and storage and management of a large amount of film Eliminates discomfort In addition, all the information about the patient, such as the image data and the reading state, the reading findings, the patient's personal information, medical history, and the medical procedure, etc., which are the photographic images of the patient thus obtained, are stored and managed in the data storage server, and the high-speed communication network By using this system, the medical personnel can read the patient's information at any place and treat and prescribe the information into one system to unify the diversity of the medical information system currently being implemented by each medical institution, and to shorten the treatment time and make accurate comparative analysis. To improve the services of medical institutions.

When integrating existing image storage system and medical information system and reading image information, it is inevitable to compare the screen of several pictures. Difficulty in making accurate readings. In order to solve this problem, according to the method of the present invention, it is possible to accurately read a plurality of image information by displaying a plurality of photographs on a high resolution dedicated readout monitor without reducing the image screen.

As shown in FIG. 1, the photographs obtained from the various medical inspection apparatuses are converted into digital data at the receiving unit without going through the film process and converted into DICOM 3.0, an international medical imaging standard format. The patient's information is entered into a file stored in a standard format and automatically stored in the data storage server. The data storage server stores the data recently inputted, and if the amount of data increases, the data is sent to the data backup department after a certain period of time, and stored in a storage medium such as an optical disk or CD-ROM to be systematically classified, stored, and managed. . In addition, by using a computer using a high-speed communication network, medical examination information of a patient can be viewed and read from a remote location, and a prescription or finding can be inputted for treatment. Also, if necessary, statistics and analysis of patient information can be performed for clinical research. When a photograph is sent to a medical society or another medical institution for the purpose of academic exchange or joint medical examination, it can be printed on a film printer and made into a film-type medium at any time.

As shown in FIG. 2, various kinds of image data obtained from various kinds of medical examination apparatuses are converted into digital format and stored in the international medical imaging standard format. First, images obtained from radiographic apparatuses such as X-ray can be digitalized. Because it cannot be saved, it is stored in film form, and then the image is inputted by digital film scanner, converted into digital form, and then saved in international medical image standard format. It is saved automatically.

However, tomography pictures, such as MRI and CT, can be digitalized directly, so they are automatically received in digital form at the receiver. And because these tomography images come out in large quantities, they are immediately read by the radiology department, and only the important photographs needed for medical examination are extracted, stored in the international medical image standard format, and the patient's information is entered and saved automatically in the data storage server. .

In addition, ultrasound or endoscopy images cannot be stored in digital form because the results are analog signals. In the present invention, such an analog signal is captured by the image capturing unit, converted into a digital image, and then stored in an international medical image standard format, and then inputted together with general information of a patient and automatically stored in a data storage server through a computer network.

As shown in FIG. 3, when a medical practitioner inquires medical information data in the present invention, a medical practitioner or a dictionary is provided through an intranet that can be used only by a limited user, which is not disclosed among internal computer communication networks and external computer communication networks, that is, the Internet network. Since only authorized users can use it, security of information such as patient information and medical history can be maintained. In addition, the computer communication network can be used to inquire the patient's information or medical test photographic data for clinical use, research, etc. through the Internet communication network in hospitals, business places, or homes. Because the doctor can lower the cost, the doctor will be able to see the doctor even if they do not have to stay in the hospital. And since there is no problem of film breakage or loss that can be brought from the inspection film transport, the data is stored permanently so that accurate reading can be performed by displaying the original screen at all times. And since the photographic data of the medical test results are stored in the data storage server in real time, the test time is reduced to the minimum, thereby reducing the time for medical treatment and increasing the efficiency of medical treatment.

As shown in FIG. 4, when a medical practitioner requests a patient's data to a data storage server remotely in or out of a hospital, the latest data is transmitted directly from the data storage server, and a certain period has elapsed, such as an optical disk or a CD-ROM. In case of the data backed up and stored in the auxiliary storage medium, it is transferred from the backup device to the data storage server. The transmitted data can be viewed anywhere in the hospital or outside the intranet with a dedicated reading viewer. When reading image data in the reading viewer, it can be viewed as a general monitor or a read-only multi-monitor. At this time, it is possible to read through general monitors where there is no read-only multi-monitor, and both methods can enlarge and reduce the image and display the necessary information directly on the point of interest of the video picture screen. By configuring the slide screen in order of the date of treatment, it is possible to understand at a glance the patient's medical history or the progress of the treatment. In order to compensate for the difficulty of reading due to screen reduction to compare multiple screens, and to improve the trouble of changing or reducing screens in order to read multiple screens in order for clearer reading, a read-only multi-monitor By displaying several video screens at the same time, it is possible to compare and read several video screens at once.

In addition, as shown in Figure 4, if you want to output the screen in the form of film after reading the necessary data, it is also possible to reproduce and copy the original film at any time by directly outputting the digital data in the data storage server in the form of film through the film printer . At this time, the digital data to be output is excluded from the compression process in order to prevent data loss in the input process, so the data output to the film is output as the original quality.

As described above, the present invention does not require the storage of huge film data, so that the storage space of medical reading data of medical institutions is reduced, thus reducing the waste of space and reducing the time and labor costs by systematically managing the data using a computer. Reduce the burden of hospital finances. In addition, since data can be easily backed up, there is no fear of data loss or damage. In addition, the Intranet enables the medical practitioner to immediately view the patient's photographic images and input the findings, findings, etc. in a computer or hospital where computer communication is possible. It is possible to improve the quality of medical services and to establish a more efficient hospital operation system by establishing a medical information system.
