The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1 is a schematic flowchart of an image capturing method according to an embodiment of the present invention, where the embodiment is applicable to a case where a target captured image of a current detected object is automatically acquired, and the method may be executed by a control device of an image capturing system, where the apparatus may be implemented by software and/or hardware. Referring specifically to fig. 1, the method may include the steps of:
s110, acquiring identity information and check information of the current detection object.
The identity information may include an identity card number, a name, a gender, a shape characteristic, and the like of the current detection object, and the shape characteristic may include a height, a weight, and the like of the current detection object. It can be understood that, before the current detected object enters the scanning room, the image acquisition system may first enter the identity information of the current detected object, and establish a personal information base for the current detected object, which may include establishing a coding information base, a facial image base, a physical sign information base, and the like. When a current detection object enters a scanning room for detection, the identity information of the current detection object is obtained, and the detection information is determined according to the identity information. Alternatively, the identity information may be determined from face information, number information, or infrared information of the current detection object.
The examination information may be understood as an examination item, and the examination item may include imaging attribute information, such as an imaging system (e.g., a CT device, an MR device, or an X-ray device) used for imaging, an imaging position, an imaging part, and the like, which is given by a doctor or a technician according to a diagnosis of a current examination object, and the examination information may be given and uploaded by the doctor or the technician at the time of an on-site examination and stored (e.g., stored locally in a PACS or an image acquisition system) or may be pre-stored instead of the on-site examination. It is understood that the check information may be bound with the identity information, that is, after the identity information of the current detection object is determined, the check information of the current detection object may be determined. It can be understood that, when the image is collected by the shooting device, each piece of inspection information corresponds to the target positioning information and the preset exposure information, so that the shooting device can scan the current detection object according to the target positioning information and the preset exposure information.
And S120, automatically determining the equipment target positioning state and the target exposure information of the shooting equipment based on the identity information and the checking information, and automatically adjusting the shooting equipment to the equipment target positioning state.
In this embodiment, the image acquisition system may establish, in advance, a correspondence between the inspection information and the equipment positioning state, the exposure information, and the positioning information of the detection standard object according to the inspection information of a plurality of detectors, and store the correspondence in the database, and when the identity information and the inspection information of the current detection object are acquired, the equipment target positioning state and the target exposure information may be determined according to the inspection information. The device target positioning state corresponds to device target positioning information, the device target positioning information can be positioning parameters set for the shooting device by a current detection object, and the positioning parameters can include the height of a check bed of the shooting device, a scanning angle and the distance from a bulb to a detector; the target exposure information may be understood as exposure parameters set for the photographing apparatus with respect to the currently detected object, and the exposure parameters may include an exposure dose value, a voltage value, a current value, a focal length, and the like. Alternatively, the photographing apparatus may be a DR apparatus, a radiotherapy apparatus, or other apparatuses.
Further, after the target setting state of the device is determined, a control instruction may be generated according to the target setting state of the device, and the shooting device may be adjusted from the current setting state to the target setting state of the device according to the control instruction. Optionally, the control instruction may include a coarse adjustment instruction and a fine adjustment instruction, so that the shooting device adjusts the setting state to the device target setting state according to the coarse adjustment instruction and the fine adjustment instruction. Alternatively, the control command may be a height adjustment command of the examination bed, a scanning angle adjustment command, a distance adjustment command from the bulb to the detector, and the like.
For example, when an image is captured by the shooting device, different detection objects correspond to different device target positioning states, or different inspection items of the same detection object also correspond to different device target positioning states. For example, when a chest is examined, a chest righting piece is generally obtained, that is, a bulb tube needs to be rightly opposite to the chest, when legs are examined, leg images at different angles need to be obtained, that is, a rotation angle is needed so as to collect images at different angles, and when chest righting images are collected for detection objects with high height and low height, the heights of detectors are also different, that is, the target positioning states of equipment are different, and an image collection system needs to control shooting equipment to be adjusted from the current positioning state to the target positioning state of the equipment according to the target positioning states of the equipment so as to collect images later. Compared with the prior art, the method has the advantages that the identity information and the check information are automatically acquired, the equipment target positioning state and the target exposure information of the shooting equipment are automatically determined according to the identity information and the check information of the current detection object, the inquiry process of a technician is replaced, the detection automation is improved, meanwhile, the artificial errors existing in artificial inquiry and the determination of the equipment target positioning state and the target exposure information are avoided, the positioning information and the exposure information of the shooting equipment do not need to be determined in an artificial mode, and the positioning efficiency and the positioning accuracy are improved.

It can be understood that after the positioning state of the shooting device is adjusted, since the target positioning state of the device corresponds to the identity information and the inspection information of the current detection object, and the target positioning state of the device needs to be matched with the target positioning state of the object to expose the current detection object, the target positioning state of the object can be determined according to the identity information and the inspection information in the implementation, that is, the current detection object can be automatically guided to adjust the positioning state to the target positioning state of the object based on the identity information and the inspection information.
Illustratively, Zhang III wants to shoot the chest radiography through the shooting device, the control device controls the shooting device to adjust to a device target swing state according to the identity information and the examination information of Zhang III, when the shooting device is adjusted to the device target swing state, the device target swing state (such as the height of an examination bed, the scanning angle and the distance from a bulb to a detector) is uniquely determined, and the target swing state of Zhang III corresponds to the device target swing state, so that the Zhang III can be automatically guided to adjust the scanning part, the scanning direction and the like according to the identity information and the examination information. Therefore, the current detection object can be automatically guided to be positioned through the control equipment. Compared with the prior art, the method and the device do not need to guide the detection object through a technician to adjust the swing state, and the workload of the technician is reduced.
In this embodiment, when it is determined that the current detection object is in the object target positioning state, the control device sends an exposure control instruction to the shooting device, and the shooting device receives the exposure control instruction and exposes the current detection object according to target exposure information corresponding to the exposure control instruction to obtain a target acquisition image. Compared with the prior art, the exposure control method has the advantages that after the placement is finished, a technician does not need to manually adjust the exposure parameters to perform exposure, exposure adjustment time is shortened, and even exposure control operation does not need to be performed by the technician.
According to the technical scheme of the embodiment of the invention, the equipment target positioning information and the target exposure information of the shooting equipment are automatically determined based on the identity information and the inspection information by acquiring the identity information and the inspection information of the current detection object, the shooting equipment is automatically adjusted to be in the equipment target positioning state, the current detection object is automatically guided to be positioned to be in the object target positioning state based on the identity information and the inspection information, and the shooting equipment is automatically controlled to expose the current detection object by the target exposure information in response to the current detection object being positioned to be in the object target positioning state, so that the target acquisition image is obtained. Different from the prior art, the method does not need to manually adjust the position setting state of the corresponding equipment or guide a technician to adjust the position setting state of the current detection object, and does not need to manually control exposure after the position setting state is adjusted, so that the problems that in the prior art, when a plurality of patients to be shot exist, the working efficiency and the accuracy of the shot image are difficult to ensure are solved, the purposes of automatically guiding and adjusting the position setting state and automatically guiding the user to position and automatically controlling the exposure are achieved, and the effects of improving the working efficiency and the accuracy of the shot image are achieved.
