For example, the processing device 120 may access information and/or data from the imaging device 110, the operation terminal 130, and/or the reminder device 150 via the network 140. As another example, the processing device 120 may be directly connected to the imaging device 110, operate the operation terminal 130, and/or the reminder device 150 to access information and/or data.

Fig. 2 is a flow chart of an imaging process control method of an imaging device according to some embodiments of the present application.

In particular, the process 200 may be performed by the processing device 120. For example, the flow 200 may be stored in the memory unit of the processing device 120 in the form of a program or instructions that, when executed by the system 100, may implement the flow 200 for an imaging device imaging process control method. As shown in fig. 2, the process 200 may include the following steps.

Step S1, responding to an imaging preparation instruction, broadcasting first reminding information, and reminding a target object to screen breath.

In particular, this step may be accomplished by the processing device 120 and the reminder device 150.

In some embodiments, the operator may send an imaging preparation instruction (e.g., pressing an imaging preparation button or a hand brake) via the operation terminal 130, and the processing device 120 may enter the imaging device 110 into the imaging preparation state in response to receiving the imaging preparation instruction. In some embodiments, the imaging device 110 may move the emitter 111 to an exposure initial position for exposure imaging.

Meanwhile, the processing device 120 sends a broadcasting instruction to the reminding device 150, where the reminding device 150 broadcasts the first reminding information, for example, broadcasts (for example, voice "please breathe deeply back breath hold" and/or display video, picture) in a carrier form of one or more of image, video or sound, so as to remind the target object (the subject) to hold breath, so that the subject keeps a stable posture, and the imaging definition and accuracy effect are improved conveniently.

And S2, collecting image information of the target object, identifying the gesture of the target object, and judging whether the target object is in a breath-hold gesture.

In particular, this step may be accomplished by the reminder device 150 and the processing device 120.

During imaging, if the subject cannot keep the breath-hold state, the definition and accuracy of the imaging are affected due to the fact that the inner cavity moves more during breathing.

In some embodiments, the alert device 150 includes a thermal imaging apparatus to capture thermal imaging image information of the acquisition target object (subject) and send to the processing device 120 for recognition to determine whether the target object is in a breath-hold state.

In some embodiments, the reminding device 150 may collect thermal imaging image information of the target object in a preset period, for example, image collection is performed at intervals of 0.5s, 1s, 2s, etc., which satisfies accuracy of sampling the respiratory period and may reduce workload of image analysis.

In some embodiments, the acquired thermal imaging image may be analyzed frame-by-frame by a preset thermal imaging image model based on the acquired thermal imaging image information. Specifically, the thermal imaging image model is built by taking a thermal imaging image of the respiratory airflow of the human breath as a sample, and the image features of the respiratory airflow are marked and stored in the storage unit of the processing device 120. The processing device 120 determines whether the target object is in a respiratory posture by comparing the thermal imaging image information sent by the reminding device 150 with the thermal imaging image model.

In other embodiments, the reminding device 150 may also be used to capture dynamic images of the target object, such as by using a camera to capture continuous image information of the subject after standing in the imaging position. And then, by combining the changes between adjacent image frames with a preset gesture recognition model, the gesture change of the detected person is recognized so as to judge the breathing or breath-hold gesture of the detected person.

But the accuracy of image recognition is lower due to the smaller external motion of the breath. Particularly when the subject wears more clothes, it is more difficult to determine whether the subject is in a breath-hold state.

And by adopting the analysis and identification of thermal imaging image information, the accuracy is greatly improved by carrying out identification and judgment through hot air flow generated by respiration.

In some embodiments, if the target object is determined to be in the respiratory posture, the reminding device 150 may broadcast the first reminding information again to remind the subject to keep the breath-hold posture, and at the same time, repeat the steps of image acquisition and recognition to confirm the posture of the subject.

And step S3, controlling the imaging equipment to perform exposure imaging on the target object according to the posture of the target object.

Specifically, this step may be accomplished by the processing device 120 and the imaging device 110.

In some embodiments, the processing device 120 sends a signal to the operation terminal 130 when it determines that the target object is in the breath-hold posture. After the operator knows, the operator can directly send an exposure imaging instruction to the imaging device 110 to perform exposure imaging; or transmits an exposure imaging instruction to the processing apparatus 120, and the processing apparatus 120 operates the imaging apparatus 110 to perform exposure imaging by a preset instruction.

In some embodiments, imaging device 110 receives exposure imaging instructions and may drive emitter 111 up/down to perform exposure scanning of a target object to form a medical image. For example, when the subject stands between the imaging devices 110 in the imaging preparation stage, the emitter 111 is located at the exposure initial position; when receiving the exposure imaging instruction, the emitter 111 starts moving from the exposure initial position, performs scanning exposure, moves to the exposure completion position, and completes exposure imaging.

In other embodiments, imaging device 110 receives exposure imaging instructions and may drive probe plate 112 up/down to perform exposure scanning of a target object to form a medical image. At this time, the emitter 111 performs exposure, and the probe card 112 moves in synchronization and receives radiation to form an image.

And S4, completing exposure imaging, broadcasting second reminding information, and reminding a target object of releasing the breath-hold gesture.

In particular, this step may be accomplished by the processing device 120 and the reminder device 150.

In some embodiments, after imaging device 110 completes exposure imaging, processing device 120 sends a signal to alert device 150 in response to the exposure imaging complete signal; the reminder device 150 receives the signal and broadcasts a second reminder signal, such as in the form of a carrier of one or more of an image, video or sound (e.g., voice "please release breath-hold, normal breath" and/or show video, picture), reminding the target subject (subject) to release the breath-hold gesture.

Possible beneficial effects of embodiments of the present application include, but are not limited to: (1) Reminding a target object (a subject) to enter a breath-hold gesture before exposure so as to ensure the definition and accuracy of exposure; (2) The gesture information of the target object is acquired and identified through thermal imaging, the defect that the visible image cannot be accurately identified is overcome, and the identification accuracy is improved. It should be noted that, the advantages that may be generated by different embodiments may be different, and in different embodiments, the advantages that may be generated may be any one or a combination of several of the above, or any other possible advantages that may be obtained.

The imaging process control method and system of the imaging device provided by the embodiment of the application are described in detail, and specific examples are applied to explain the principle and the embodiment of the application, and the description is only used for helping to understand the method and the core mechanism of the application; meanwhile, as those skilled in the art will have modifications in specific embodiments and application scope in accordance with the ideas of the present application, the present disclosure should not be construed as limiting the present application in view of the above description.
