[0031] The present application is further described below in conjunction with the accompanying drawings and specific embodiments. The described embodiments should not be regarded as limiting the present application, and all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

[0032] In the following description, reference is made to “some embodiments”, which describe a subset of all possible embodiments, but it can be understood that “some embodiments” may be the same subset or different subsets of all possible embodiments and may be combined with each other without conflict.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein are only for the purpose of describing the embodiments of this application and are not intended to limit this application.

[0034] Before describing the present application in detail, the structure of the digital X-ray photography system is described first.

[0035] Please refer to Figure 1, an embodiment discloses a digital X-ray photography system, which at least includes an X-ray generator 10, an X-ray detector 20, a processor 30 and a display device 40, which are described below. It should be noted that, if distinguished according to the shooting position of the machine, the digital X-ray photography system can be a standing photography system, a supine photography system, a free photography system, or a shooting system integrating multiple body positions, and the embodiment of the present application does not limit this; if distinguished according to the operation mode of the machine positioning, the digital X-ray photography system can be a manually adjustable type, and the manually adjustable digital X-ray photography system can manually adjust the head height / angle, the X-ray detector 20 height / angle, the photography distance, etc., and the digital X-ray photography system can also be an automatically adjustable type, and the automatically adjustable digital X-ray photography system can adjust the head height / angle, the X-ray detector 20 height / angle, the photography distance, etc. through motor drive.

[0036] The X-ray generator 10, also called the head device, is used to generate X-rays. For example, the X-ray generator 10 may include an X-ray tube filament as a cathode and a target metal (such as tungsten or molybdenum) as an anode. By supplying power and heating the X-ray tube filament, free electrons are generated near the cathode. When high voltage (tens or hundreds of kV) is supplied to the two poles, the potential difference between the cathode and the anode increases sharply, and the electrons travel from the cathode to the anode at a high speed, bombarding the anode target metal to generate energy, wherein less than 1% of the energy is converted into X-rays and more than 99% is converted into heat energy, thereby generating X-rays. In some embodiments, referring to Figure 3 The X-ray generator 10 includes a ray source 11, a beam limiter 12 and a filter 13, wherein the beam limiter 12 and the filter 13 are sequentially arranged behind the ray source 11, the ray source 11 is used to generate X-rays, the beam limiter 12 is used to block unnecessary primary X-rays, and the filter 13 is used to filter X-rays. In some embodiments, the position (such as height, horizontal position, etc.) and angle of the X-ray generator 10 are adjustable.

[0037] The X-ray detector 20 is used to receive the X-rays generated by the X-ray generator 10 and penetrating the human body 50 to be photographed, and convert the received X-rays into electrical signals. For example, the X-ray detector 20 includes a front shell, a ray conversion layer, a photoelectric conversion layer, a supporting structure, a circuit board and a rear shell. Among them, the ray conversion layer is used to convert the rays into visible light. The ray conversion layer generally includes a scintillation layer or a fluorescent layer, which is used to convert the rays into visible light. Taking the scintillation layer as an example, it can generally be made of scintillation materials, typically such as cesium iodide (CsI) or gadolinium oxysulfide (GOS). The photoelectric conversion layer can be a TFT matrix layer, which is used to sense the visible light converted by the ray conversion layer, and convert the visible light into an electrical signal for image information acquisition. In some embodiments, the X-ray detector 20 can be a flat panel detector 21, or it can be other forms of X-ray detectors 20, which are not limited in the embodiments of the present invention. In some embodiments, refer to Figure 3 The X-ray detector 20 includes a flat panel detector 21, an ionization chamber 22 and a grid 23. The ionization chamber 22 and the grid 23 are arranged in front of the flat panel detector 21 (between the human body 50 to be photographed and the flat panel detector 21) and behind the bed board 60. The grid 23 is used to eliminate scattered light to make the imaging of the X-ray detector 20 clearer. The ionization chamber 22 is used to measure ionizing radiation.

[0038] For example, refer to Figure 3 , is a structural diagram of a horizontal digital X-ray photography system, including an X-ray generator 10, a bed surface and an X-ray detector 20. The X-ray generator 10 includes a ray source 11, a beam limiter 12 and a filter 13, and the X-ray detector 20 includes a flat panel detector 21, an ionization chamber 22 and a filter grid 23. The X-rays generated by the ray source 11 are emitted after passing through the beam limiter and the filter 13; the emitted X-rays pass through the human body 50 to be photographed and are received by the X-ray detector 20; the X-rays passing through the human body 50 to be photographed pass through the filter grid 23 and the ionization chamber 22 in sequence, and are then received by the flat panel detector 21.

[0039] The processor 30 may be the nerve center and command center of the digital X-ray photography system, or the command center responsible for machine posture control or display control in the digital X-ray photography system. The processor 30 may generate an operation control signal according to the instruction operation code and the timing signal to complete the control of fetching and executing instructions. For example, in some embodiments, the processor 30 may receive an electrical signal obtained from the X-ray detector 20 and perform corresponding processing to obtain a photographic image of a human body to be photographed; or, the processor 30 may output a control signal to control the machine posture, such as the angle of the X-ray generator 10, the position of the X-ray generator 10, the height of the X-ray generator 10, the angle of the X-ray detector 20, the height of the X-ray detector 20, the photographic distance, the exposure parameters, the presence or absence of a grid, the presence or absence of filtration, the X-ray dose, etc.; or, the processor 30 may obtain the current machine state obtained from the machine posture sensor; or, the processor 30 may control the display device 40 to display information, such as displaying dynamic shooting indication information. The functions and execution steps of the processor 30 will be further described below.

[0040] The display device 40 is used to receive and display the shooting instruction information. In some embodiments, the digital X-ray imaging system itself can integrate the display device 40. In some embodiments, the digital X-ray imaging system can also be connected to a terminal device (such as a personal computer, a tablet computer, a mobile phone, etc.) to display information through the display unit (such as a display screen) of the terminal device. These are all within the scope defined and protected by the display device 40 in this article. The display device 40 can be used for technicians to watch or for patients to watch. For example, the display device 40 can be used for technicians to watch. The technician can adjust the machine status or correct the patient's posture on the spot according to the shooting instruction information displayed by the display device 40.

[0041] For example, Figure 2 As shown, it is a structural schematic diagram of an integrated vertical and horizontal digital X-ray imaging system, which includes a standing X-ray receiving device 100, a horizontal X-ray receiving device 200, a head device 300 and a processor (not shown in the figure). In this example, the X-ray imaging system may include a standing X-ray imaging system and a horizontal X-ray imaging system. The standing X-ray imaging system may include a standing X-ray receiving device 100, a head device 300 and a processor (not shown in the figure), which is mainly used to realize standing X-ray imaging, such as standing chest X-ray imaging. The horizontal X-ray imaging system may include a horizontal X-ray receiving device 200, a head device 300 and a processor (not shown in the figure), which is mainly used to realize lying X-ray imaging, such as lying X-ray imaging under the bed. The following is mainly described with an X-ray imaging system that can have both standing and lying positions, and these structures can also be applied to the corresponding standing X-ray imaging system and horizontal X-ray imaging system.

[0042] The standing X-ray receiving device 100 (such as a standing chest X-ray receiving device) includes a column 110 and a first X-ray detector 120. The first X-ray detector 120 is mounted on the column 110 in a manner that it can move in the vertical direction. There are multiple standing flat panel fixing positions on the moving track of the first X-ray detector 120. The standing flat panel fixing positions are distributed at different heights in the vertical direction. The first X-ray detector 120 can be fixed at the standing flat panel fixing positions and rotated at a certain angle to adjust the position or angle of the first X-ray detector 120.

[0043] The horizontal X-ray receiving device 200 (under-bed supine X-ray receiving device) comprises a bed body 210, a bed board 220 mounted on the bed body 210, and a second X-ray detector (blocked in the figure). The position and angle of the second X-ray detector are adjustable.

[0044] The head device 300 includes a support 310 and a head 320 (X-ray generator) mounted on the support 310. The head 320 can emit X-rays to the corresponding first X-ray detector 120 and second X-ray detector. The head device 300 can move relative to the support to adjust the position of the head device; the head device 300 can also rotate relative to the support to adjust the angle of the head device.

[0045] It should be noted that the structure of the digital X-ray imaging system described in the embodiment of the present invention is for the purpose of more clearly illustrating the technical solution of the embodiment of the present invention, and does not constitute a limitation on the technical solution provided by the embodiment of the present invention. Those skilled in the art will appreciate that with the evolution of the device architecture and the emergence of new application scenarios, the technical solution provided by the embodiment of the present invention is also applicable to similar technical problems.

[0046] It can be understood by those skilled in the art that Figure 1 and Figure 2 The digital X-ray imaging system shown in the figure does not constitute a limitation on the embodiments of the present invention, and may include more or less components than those shown in the figure, or combine certain components, or arrange the components differently.

[0047] exist Figure 1 and Figure 2 In the digital X-ray imaging system shown, the processor can call its stored program to execute the positioning instruction process control.

[0048] During the filming process of the digital X-ray system, the correct positioning directly affects the image quality and the difficulty of diagnosis. At present, the film positioning requires technicians (such as doctors in charge of filming) to consider comprehensive factors based on the current filming environment. It has high technical requirements for technicians and generally requires professional on-the-job training, which is time-consuming and laborious.

[0049] The recommended positioning in different environments can fully reflect the performance of the digital X-ray system and obtain the best image effect, which needs to be conveyed to the operator intuitively and correctly.

[0050] In actual applications, the applicant found that different digital X-ray photography systems have different functions, some are more comprehensive, and some are more streamlined. Generally speaking, low-end digital X-ray photography systems have a lower degree of automation, and low-end digital X-ray photography systems have a higher degree of automation. From the perspective of the machine, it can be divided into standing position, supine position and free position (the machine head or detector can move freely); from the perspective of the patient's posture, it can be divided into anteroposterior position, lateral position, oblique position, etc.

[0051] In the related art, the patient is generally instructed to position the body through text descriptions or static diagrams in the manual. The former requires conversion from text to scenes, which is difficult to understand correctly and may introduce errors; the latter directly displays the positioning results and lacks operating instructions for the positioning process. In addition, the related art lacks instructions for the machine's posture positioning, which requires high technical skills of the technician.

[0052] The embodiments of the present application provide a positioning instruction method, system and storage medium for an X-ray imaging system, which automatically generates and displays dynamic shooting instruction information according to shooting position parameters, so as to facilitate technicians to perform film positioning according to the shooting instruction information, effectively improve shooting efficiency and imaging quality, and reduce professional requirements for technicians, thereby saving manpower and material resources.

[0053] Please refer to Figure 4 The present application embodiment discloses a positioning indication method for an X-ray imaging system, the method comprising:

[0054] Step S1100, obtaining shooting position parameters, wherein the shooting position parameters are used to characterize the X-ray photography position of the human body to be photographed;

[0055] Step S1200, determining at least one key positioning factor index corresponding to the shooting position parameter according to the shooting position parameter, where the key positioning factor index includes a human body state index and at least one machine state index related to the imaging condition;

[0056] Step S1300, generating dynamic shooting instruction information according to the key positioning factor indicators. The dynamic shooting instruction information includes: first shooting instruction information for indicating the dynamic action process of adjusting from the initial human body state to the target human body state, second shooting instruction information for indicating the dynamic action process of adjusting from the initial machine state to the target machine state, and third shooting instruction information for indicating multiple positional relationships; the dynamic form includes video or a dynamic image spliced ​​from multiple frames of images, the third shooting instruction information for indicating multiple positional relationships includes a dynamic image spliced ​​from multiple frames of images corresponding to the multiple positional relationships, and the multiple frames of images corresponding to the multiple positional relationships include: a global image reflecting the positional relationship between the entire machine and the human body to be photographed, a local close-up image reflecting the positional relationship between the X-ray generator and the X-ray detector, and a local close-up image reflecting the positional relationship between the X-ray generator and the human body to be photographed.

[0057] Step S1400: display dynamic shooting instruction information, where the dynamic shooting instruction information is used to instruct the user to adjust the machine status.

[0058] It is understandable that the embodiment of the present application will index the key factors that determine the filming position, quantify the qualitative indicators (such as position, angle, dose range, presence or absence of filter wire grid, etc.), and then generate the shooting instruction information based on the quantitative key factor indicators. Among them, the correspondence between the key factor indicators of the filming position and the shooting position parameters can be preset. For example, the correspondence table between the key factor indicators and the shooting position parameters can be set in combination with experience, textbook guidance and the characteristics of the machine itself.

[0059] In some embodiments, the shooting posture parameters may be input by a user, or may be automatically acquired by scanning an examination form, which is not limited in this embodiment of the present application.

[0060] The shooting position parameters are used to characterize the X-ray photography position of the human body to be photographed. Exemplarily, the body position may include the anterior-posterior position, the posterior-anterior position, the dorsal-ventral direction, the dorsal-ventral direction, the center line parallel to the body axis of the irradiated body (axial direction), the left-right direction, the right-to-left direction, the direction in which the center line is incident on the edge of the irradiated part and is tangent to the lesion (tangent direction), the first oblique direction of the dorsal-ventral direction (X-ray enters from the left rear), the second oblique direction of the dorsal-ventral direction (X-ray enters from the right rear), the first oblique direction of the dorsal-ventral direction (X-ray enters from the right front of the body), and the second oblique direction of the dorsal-ventral direction (X-ray enters from the left front of the body).

[0061] Exemplarily, the key factor indicators that affect the filming position can be extracted and quantified according to the shooting position parameters, and the key factor indicators can be arranged and combined (that is, according to different key factor indicator value combinations). That is, shooting instruction information under different conditions can be generated according to the body position, and voice or icon instructions can be added to the shooting guidance information to indicate the accurate position information (such as X-ray generator height / angle, flat panel detector height / angle, etc.). Among them, the mapping relationship between different key factor indicator value combinations and shooting instruction information can be pre-configured, and the shooting instruction information corresponding to the key factor indicator value combination can be obtained by querying the pre-configured mapping relationship table; the key factor indicator value combination can also be calculated through a preset algorithm relationship to obtain the corresponding shooting instruction information.

[0062] It is understandable that the dynamic shooting instruction information includes at least the second shooting instruction information. The embodiment of the present application includes adjusting the machine status, such as the height and angle of the flat panel detector, the height and angle of the X-ray generator, the height of the bed, SID (Source to Image receptor Distance, photography distance), the size of the irradiation field, the presence or absence of a filter grid, the dose size, the presence or absence of filtration, etc. The standard of the machine status varies depending on the body position. The general principle is to minimize the radiation received by the photographed human body while ensuring the shooting effect.

[0063] In some optional embodiments, the machine status indicator includes at least one of the following:

[0064] X-ray generator angle, X-ray generator position, X-ray detector angle, X-ray detector position, photographic distance, exposure parameters, presence or absence of grid, presence or absence of filtration, beam limiter opening size, X-ray dose, etc.;

[0065] The second shooting instruction information includes at least one of the following:

[0066] X-ray generator angle adjustment instruction information, X-ray generator position adjustment instruction information, X-ray detector angle adjustment instruction information, X-ray detector position adjustment instruction information, photography distance adjustment instruction information, exposure parameter adjustment instruction information, loading or removing filter grid instruction information, loading or removing filter instruction information, beam limiter opening size adjustment instruction information, X-ray dose adjustment instruction information, etc.

[0067] It is understandable that the values ​​of key factor indicators corresponding to the machine status can be determined based on clinical application standards or industry experience.

[0068] Exemplarily, the position of the X-ray generator refers to the spatial position of the X-ray generator, including height, horizontal position, etc. The position of the X-ray detector refers to the spatial position of the X-ray generator, including height, horizontal position, etc. The unit of X-ray dose is milliampere / millisecond. The X-ray imaging system can adjust the X-ray dose by adjusting the voltage between the cathode and anode of the X-ray generator, or adjusting the exposure time per unit time. Exposure parameters include aperture parameters, sensitivity parameters, etc.

[0069] It can be understood that the second shooting instruction information can be an automated adjustment instruction content, such as an instruction to adjust the machine status indicator by pressing a button; it can also be a manual adjustment instruction content, such as an instruction to adjust the machine status indicator by manual operation. The embodiment of the present application does not limit this.

[0070] In some optional implementations, the key positioning factor index also includes a human body state index, and the dynamic shooting instruction information also includes first shooting instruction information, and the first shooting instruction information is used to instruct the user to adjust the human body state.

[0071] In some embodiments, the shooting position adjustment can be divided into machine state adjustment and human state adjustment. The machine state includes the angle of the X-ray generator, the position of the X-ray generator, the angle of the X-ray detector, the position of the X-ray detector, the shooting distance, the exposure parameters, the presence or absence of a grid, the presence or absence of filtration, the opening size of the beam limiter, the X-ray dose, the height of the bed, etc. The embodiment of the present application implements the instruction of the machine state adjustment through the second shooting instruction information. The human state adjustment includes the posture and position of the person relative to the machine (mainly the flat-panel detector). The embodiment of the present application implements the instruction of the machine state adjustment through the first shooting instruction information, such as instructing the patient to get as close to the flat-panel detector as possible.

[0072] Exemplarily, the X-ray generator angle, X-ray generator position, X-ray detector angle, X-ray detector position, bed height and other information can also be displayed in the second shooting instruction information using icons. For example, the height (vertical distance) or horizontal distance of the X-ray generator can be displayed using a distance line segment with an arrow and a distance value; optionally, as the position of the X-ray generator changes, the length of the distance line segment and the distance value change accordingly. For another example, the angle between the X-ray generator and the bracket can be displayed in the second shooting instruction information using an arc and an angle value; optionally, as the angle of the X-ray generator changes, the length of the arc and the angle value change accordingly. The present application not only implements the indication of the adjustment of the human body state, but also implements the indication of the adjustment of the machine state, thereby facilitating the technician to perform filming positioning according to the shooting instruction information, which can effectively improve the shooting efficiency and imaging quality, and reduce the professional requirements for technicians, thereby saving manpower and material resources.

[0073] In some optional embodiments, the human body state indicator includes at least one of the following: human body posture, human body position;

[0074] The first shooting instruction information includes at least one of the following:

[0075] Human body posture adjustment instruction information, human body position adjustment instruction information.

[0076] It can be understood that the human body state adjustment includes the posture and position of the person relative to the machine (mainly the flat-panel detector). The embodiment of the present application implements the instruction of the machine state adjustment through the first shooting instruction information, such as instructing the patient to get as close to the flat-panel detector as possible.

[0077] It can be understood that the third shooting indication information is used to indicate multiple positional relationships; the third shooting indication information used to indicate multiple positional relationships includes a dynamic image stitched together from multiple frame images corresponding to the multiple positional relationships, and the multiple frame images corresponding to the multiple positional relationships include: a global image reflecting the positional relationship between the machine as a whole and the human body to be photographed, a local close-up image reflecting the positional relationship between the X-ray generator and the X-ray detector, and a local close-up image reflecting the positional relationship between the X-ray generator and the human body to be photographed.

[0078] Exemplarily, the positional relationship between the entire machine and the human body to be photographed can be a panoramic image containing the entire machine and the human body to be photographed, so that the user can intuitively understand the orientation information of the entire machine and the human body to be photographed; the positional relationship between the entire machine and the human body to be photographed can also be displayed in the image with an icon, for example, using a distance line segment with an arrow and a distance value to display the distance between the entire machine and the human body to be photographed, and using an arc and an angle value to display the angle between the entire machine and the human body to be photographed. The positional relationship between the X-ray generator and the X-ray detector can facilitate users to intuitively understand the positional relationship between the X-ray generator and the X-ray detector; the positional relationship between the X-ray generator and the X-ray detector can also be displayed in the image with an icon, for example, using a distance line segment with an arrow and a distance value to display the distance between the X-ray generator and the X-ray detector, and using an arc and an angle value to display the angle between the X-ray generator and the X-ray detector. The positional relationship between the X-ray generator and the human body to be photographed may include a close-up image of the X-ray generator and the human body to be photographed, so that the user can intuitively understand the positional information between the X-ray generator and the human body to be photographed; the positional relationship between the X-ray generator and the human body to be photographed may also be displayed in the image using an icon, for example, using a distance line segment with an arrow and a distance value to display the distance between the X-ray generator and the human body to be photographed, and using an arc and an angle value to display the angle between the X-ray generator and the human body to be photographed. Among them, the position of the X-ray generator may be the head part, and the above-mentioned positional relationship involving the X-ray generator may be understood as the relative position between the head part and the X-ray detector or the human body to be photographed, such as the direction and / or angle. In some optional embodiments, the type of dynamic shooting indication information includes at least one of the following:

[0079] Voice, static images, dynamic pictures, etc.

[0080] It is understandable that the dynamic shooting instruction information can be a separate voice, a static image or a dynamic picture, or any combination of the above multiple types. Among them, the dynamic picture can be a dynamic image and a video, the dynamic image can be a PPT slide, and the video is generally continuous and has sound effects.

[0081] Exemplarily, the embodiment of the present application first extracts and quantifies the key factor indicators that affect the filming position according to the shooting position parameters, arranges and combines the key factor indicators, and generates a dynamic positioning instruction animation video (shooting instruction information) under different conditions according to the position parameters. Voice or icons can be added to the video to indicate the accurate position information (head, tablet angle, SID, etc.). The positioning instruction animation is played on a large screen set at the head of the machine to guide the user (such as a technician) to correctly operate to the recommended position. The positioning dynamic instruction animation video can be instructed step by step or displayed in full; the step-by-step content can be triggered by the state of the machine, which will be described in detail later.

[0082] In some optional implementations, the type of dynamic shooting indication information includes a dynamic picture; the form of the dynamic picture includes any one of the following: a video picture, a multi-frame image picture;

[0083] Wherein, when the dynamic picture is in the form of a multi-frame image picture, the dynamic picture is a dynamic image picture composed of the multi-frame image pictures.

[0084] It is understandable that video images are generally continuous and have sound effects; multi-frame images can be PPT slides. Among them, the correspondence between the screen image and the key factor indicator can be one-to-one or many-to-one. For example, each frame of the screen image can correspond to a positioning operation indicating a key factor indicator, and the multi-frame image corresponds to the positioning operation indicating multiple key factor indicators, thereby forming a multi-frame image screen; the multi-frame image can correspond to a positioning operation indicating a key factor indicator, and the multi-frame image corresponds to the positioning operation indicating multiple key factor indicators, thereby forming a multi-frame image screen.

[0085] In some optional implementations, in step S1400, displaying dynamic shooting instruction information includes:

[0086] Step S1401, displaying the dynamic action process or dynamic control process of adjusting from the initial machine state to the target machine state;

[0087] and / or,

[0088] Step S1402, displaying the dynamic action process of adjusting from the initial human body state to the target human body state.

[0089] It is understandable that the content of the dynamic shooting instruction information can be the dynamic action process or dynamic control process of adjusting the initial machine state to the target machine state, or the dynamic action process of adjusting the initial human body state to the target human body state, or the superposition of the two, that is, the dynamic action process or dynamic control process of adjusting the initial machine state to the target machine state, and the superposition of the dynamic action process of adjusting the initial human body state to the target human body state, and the embodiments of the present application do not limit this. Among them, the dynamic action process or dynamic control process of adjusting the initial machine state to the target machine state, and the superposition of the dynamic action process of adjusting the initial human body state to the target human body state can be the superposition of the time dimension (playing in sequence), or the superposition of the space dimension (such as showing the dynamic process of both at the same time in the same dynamic picture).

[0090] Exemplarily, the initial human body state can be a preset human body state. For example, the default human body state corresponds to a posture of a human body standing next to a machine, and the target human body state is a posture in which the center line of the human body is parallel to the body axis of the object being irradiated (in the axial direction). The content of the shooting instruction information shows the dynamic movement process of the X-ray generator from the posture of the human body standing next to the machine to the posture in which the center line of the human body is parallel to the body axis of the object being irradiated (in the axial direction).

[0091] In some optional implementations, the initial machine state is a default machine state; or, the initial machine state is an actual machine state acquired by a machine state sensor at an initial moment.

[0092] It can be understood that the default machine state can be a preset machine state. For example, the corresponding X-ray generator angle in the default machine state is 0 degrees, and the corresponding X-ray generator angle in the target machine state is 30 degrees. The content of the shooting instruction information shows the dynamic movement process or dynamic control process of the X-ray generator angle from 0 degrees to 30 degrees.

[0093] It can be understood that the initial machine state can also be the actual machine state collected by the machine state sensor at the initial moment. For example, at the initial moment, the corresponding X-ray generator angle in the machine state is 25 degrees, and the corresponding X-ray generator angle in the target machine state is 30 degrees. The content of the shooting instruction information shows the dynamic movement process or dynamic control process of the X-ray generator angle from 25 degrees to 30 degrees.

[0094] It is understandable that the machine state sensor may be an angle sensor, a displacement sensor, etc. For example, the machine state sensor may be an angle sensor, and the angle of the X-ray generator corresponding to the current machine state may be acquired by using the angle sensor provided on the X-ray generator to obtain the angle of the X-ray generator corresponding to the current machine state.

[0095] In some optional implementations, in step S1300, dynamic shooting instruction information is generated according to the key positioning factor indicators, including:

[0096] Step S1310, continuously acquiring the current machine state, where the current machine state is acquired by a machine state sensor;

[0097] Step S1320, obtaining the target machine state according to the key positioning factor indicators;

[0098] Step S1330, generating dynamic shooting instruction information according to the current machine state and the target machine state, and updating the shooting instruction information according to the change of the current machine state;

[0099] Correspondingly, in step S1400, dynamic shooting instruction information is displayed, including:

[0100] Step S1411, displaying shooting instruction information including the current machine state and the target machine state, and updating and displaying dynamic shooting instruction information according to the updated current machine state.

[0101] It is understandable that the dynamic shooting instruction information can be a real-time interactive method, that is, by capturing the current machine status in real time, tracking the user's operation on the machine status, and updating the shooting instruction information in real time as the user operates the machine status.

[0102] Exemplarily, the current machine state obtained in real time can be rendered and displayed in an opaque entity; the target machine state can be rendered and displayed in a transparent or semi-transparent manner; as the user operates the machine state, the entity in the displayed dynamic picture gradually moves toward the transparent or semi-transparent target machine state. For example, the angle of the X-ray generator corresponding to the current machine state is 25 degrees, and the angle of the X-ray generator corresponding to the target machine state is 30 degrees. The content of the shooting instruction information is rendered in an opaque entity to display the X-ray generator at the 25-degree position, and rendered in a transparent frame to display the X-ray generator at the 30-degree position; as the user operates the angle of the X-ray generator, the opaque entity X-ray generator in the dynamic picture gradually moves until it overlaps with the X-ray generator at the 30-degree position of the transparent frame.

[0103] In some optional implementations, in step S1400, displaying dynamic shooting instruction information includes:

[0104] Step S1421, scrolling and playing the shooting instruction information;

[0105] or,

[0106] Step S1422, playing the shooting instruction information once;

[0107] or,

[0108] Step S1423, obtaining a play operation instruction, and starting to play, pausing to play, or stopping to play the shooting instruction information according to the play operation instruction.

[0109] It is understandable that the playback method of dynamic guidance may include but is not limited to: automatic scrolling playback as in step S1421; automatic single playback as in step S1422; and manual control of playback, pause, and end as in step S1423.

[0110] In some optional implementations, the dynamic picture includes multiple positioning indication pictures corresponding to multiple positioning key factor indicators, and the positioning indication pictures are in the form of any one of the following: video pictures, single-frame image pictures, and multi-frame image pictures.

[0111] It is understandable that the dynamic picture includes multiple positioning indication pictures (i.e., multiple second shooting indication information) corresponding to multiple positioning key factor indicators. For example, when the positioning indication picture is a video picture, the positioning indication picture is a segment of the video picture, which is used to correspond to the action process or operation process of indicating a positioning key factor indicator. When the positioning indication picture is a single-frame image picture, for example, each frame of the picture image may be a positioning operation corresponding to one key factor indicator, and multiple frames of the picture images correspond to positioning operations indicating multiple key factor indicators, thereby forming a multi-frame image picture. When the positioning indication picture is a multi-frame image picture, the multi-frame image may be a positioning operation corresponding to one key factor indicator, and the multi-frame image corresponds to positioning operations indicating multiple key factor indicators, thereby forming a multi-frame image picture.

[0112] In actual operation, the dynamic shooting instruction information can be provided in steps or displayed in full. The step-by-step instructions can be triggered by the current machine status, which will be further described below.

[0113] In some optional implementations, in step S1400, displaying dynamic shooting instruction information includes:

[0114] Step S1431, obtaining a specific positioning indication picture playback operation instruction;

[0115] Step S1432, displaying a corresponding positioning instruction screen according to the specific positioning instruction screen playback operation instruction.

[0116] The above-mentioned specific positioning instruction screen can be understood as the target second shooting instruction information among the multiple second shooting instruction information. In some embodiments, the user can arbitrarily choose which positioning instruction screen to start playing. For example, according to the user's experience and habits or the need to watch a certain clip repeatedly, the user can operate the specific positioning instruction screen playback operation instruction to make the system display the corresponding positioning instruction screen.

[0117] In some optional implementations, in step S1400, displaying dynamic shooting instruction information includes:

[0118] Step S1440, continuously acquiring the current machine state, where the current machine state is acquired by the machine state sensor;

[0119] Step S1450, displaying a corresponding positioning instruction screen according to the current machine status and preset display rules.

[0120] It is understandable that the content of the step-by-step process can be triggered by the current machine state. Two examples are given below to explain in detail.

[0121] In some optional implementations, in step S1450, according to the current machine state and the preset display rules, a corresponding positioning instruction screen is displayed, including:

[0122] Step S1451, displaying the i-th positioning instruction screen to instruct the user to adjust the i-th positioning key factor indicator, wherein i=1, 2, ..., N, and N is the number of positioning key factor indicators; when the current machine state is that the i-th positioning key factor indicator is adjusted in place, displaying the next positioning instruction screen to instruct the user to adjust the next positioning key factor indicator;

[0123] or,

[0124] Step S1452, obtain multiple current machine states corresponding to multiple positioning key factor indicators; determine whether the current machine state has reached the target machine state; based on the determination result, obtain the positioning key factor indicators that have not reached the target machine state; display the positioning indication screen corresponding to the positioning key factor indicators that have not reached the target machine state, wherein each positioning key factor indicator corresponds to a current machine state and a target machine state.

[0125] It is understandable that the preset display rule corresponding to step S1451 can be summarized as: display a positioning instruction screen corresponding to a positioning key factor indicator, obtain the corresponding adjustment status of the positioning key factor indicator, and when the positioning key factor indicator is adjusted, display the positioning instruction screen corresponding to the next positioning key factor indicator, and so on. In this way, it is convenient for technicians to make gradual adjustments and reduce the requirements for technicians' skills.

[0126] For example, the dynamic shooting instruction information can be made into a wizard-style, which sequentially instructs the adjustment of the X-ray generator angle, X-ray generator position, X-ray detector angle, X-ray detector position, shooting distance, exposure parameters, whether there is a grid, whether there is filtering, the opening size of the beam limiter, X-ray dose, etc. When i=1, the first positioning instruction screen is played as the X-ray generator angle adjustment instruction screen, and the X-ray generator angle adjustment status is continuously obtained; after the X-ray generator angle adjustment is completed, let i=2, and the second positioning instruction screen is automatically played as the X-ray generator position adjustment instruction screen, and the X-ray generator position adjustment status is continuously obtained... and so on, until all the key positioning factor indicators are adjusted.

[0127] It is understandable that the preset display rule corresponding to step S1452 can be summarized as: displaying the positioning indication screen corresponding to the positioning key factor indicators that have not reached the target machine state. That is, first determine which of the current machine states are in place (i.e., no adjustment is required) and which are not in place (i.e., adjustment is required), and then display the positioning indication screen for those that are not in place. In this way, it is convenient for technicians to directly adjust the positioning key factor indicators that are not in place, saving time for positioning adjustment.

[0128] In some optional implementations, at least one key positioning factor index is determined based on the shooting body position parameters, including:

[0129] Determine the major body position category according to the shooting body position parameters, and the major body position category includes at least one of the following: standing, sitting, semi-sitting, supine, prone, left / right side lying, left / right anterior oblique, left / right posterior oblique, etc.;

[0130] Determine a body position subcategory corresponding to the shooting body position parameters from the body position major category;

[0131] Determine the key positioning factor indicators based on the body position categories.

[0132] Exemplarily, the body position subcategories may include anterior-posterior position, posterior-anterior position, dorsal-ventral position, dorsal-ventral position, center line parallel to the body axis of the irradiated body (axial direction), left-right direction, right-to-left direction, the direction in which the center line is incident on the edge of the irradiated part and is tangent to the lesion (tangent direction), dorsal-ventral first oblique direction (X-rays enter from the left rear), dorsal-ventral second oblique direction (X-rays enter from the right rear), dorsal-ventral first oblique direction (X-rays enter from the right front of the body), dorsal-ventral second oblique direction (X-rays enter from the left front of the body), maxillomandibular position (the top of the head is against the film, from the submandibular to the top of the head), maxillomandibular position (the submandibular is against the film, from the top of the head to the submandibular), tangential position (from the local edge of the examined part to the film), axial position (parallel to the long axis of the body to reach the film, frontonasal position with the forehead and the tip of the nose close to the film, and film from the occipital region through the forehead), etc.

[0133] In some embodiments of the present application, by acquiring shooting position parameters, at least one key positioning factor indicator is determined according to the shooting position parameters, and the key positioning factor indicator includes a human body state indicator and at least one machine state indicator, and then dynamic shooting instruction information is generated according to the key positioning factor indicator, and the dynamic shooting instruction information includes at least second shooting instruction information; finally, the dynamic shooting instruction information is displayed. The embodiments of the present application automatically generate and display dynamic shooting instruction information by displaying dynamic shooting instruction information according to shooting position parameters, so as to facilitate technicians to perform filming positioning according to the shooting instruction information, which can effectively improve shooting efficiency and imaging quality, and reduce professional requirements for technicians, thereby saving manpower and material resources.

[0134] In addition, please refer to Figure 5The present application also discloses a positioning indication method for an X-ray imaging system, including:

[0135] Step S2100, obtaining a human body shooting position parameter, wherein the shooting position parameter is used to characterize an X-ray photography position of a human body to be shot;

[0136] Step S2200, generating dynamic shooting instruction information according to the human body shooting position parameters, wherein the dynamic shooting instruction information includes: first shooting instruction information for indicating the dynamic action process of adjusting from an initial human body state to a target human body state, second shooting instruction information for indicating the dynamic action process of adjusting from an initial machine state to a target machine state, and third shooting instruction information for indicating multiple positional relationships; wherein the dynamic form includes a video or a dynamic image spliced ​​from multiple frames of images, wherein the third shooting instruction information for indicating multiple positional relationships includes a dynamic image spliced ​​from multiple frames of images corresponding to the multiple positional relationships, and the multiple frames of images corresponding to the multiple positional relationships include: a global image reflecting the positional relationship between the entire machine and the human body to be photographed, a local close-up image reflecting the positional relationship between the X-ray generator and the X-ray detector, and a local close-up image reflecting the positional relationship between the X-ray generator and the human body to be photographed;

[0137] Step S2300: display dynamic shooting instruction information, where the dynamic shooting instruction information is used to instruct the user to adjust the machine status.

[0138] It is understandable that the shooting posture parameters may be input by the user or automatically acquired by scanning the examination form, and this embodiment of the present application does not limit this.

[0139] The shooting position parameters are used to characterize the X-ray photography position of the human body to be photographed. Exemplarily, the body position may include the anterior-posterior position, the posterior-anterior position, the dorsal-ventral direction, the dorsal-ventral direction, the center line parallel to the body axis of the irradiated body (axial direction), the left-right direction, the right-to-left direction, the direction in which the center line is incident on the edge of the irradiated part and is tangent to the lesion (tangent direction), the first oblique direction of the dorsal-ventral direction (X-ray enters from the left rear), the second oblique direction of the dorsal-ventral direction (X-ray enters from the right rear), the first oblique direction of the dorsal-ventral direction (X-ray enters from the right front of the body), and the second oblique direction of the dorsal-ventral direction (X-ray enters from the left front of the body).

[0140] Exemplarily, different shooting instruction information can be generated according to shooting position parameters, and voice or icon instructions can be added to the shooting instruction information to indicate the accurate position information (such as X-ray generator height / angle, flat panel detector height / angle, etc.). The mapping relationship between different shooting position parameters and shooting instruction information can be pre-configured, and the shooting instruction information corresponding to the key factor indicator value combination can be obtained by querying the pre-configured mapping relationship table; the key factor indicator value combination can also be calculated through a preset algorithm relationship to obtain the corresponding shooting instruction information.

[0141] It is understandable that the dynamic shooting instruction information includes at least the second shooting instruction information. The embodiment of the present application includes adjusting the machine status, such as the height and angle of the flat panel detector, the height and angle of the X-ray generator, the height of the bed, SID (Source to Image receptor Distance, photography distance), the size of the irradiation field, the presence or absence of a filter grid, the dose size, the presence or absence of filtration, etc. The standard of the machine status varies depending on the body position. The general principle is to minimize the radiation received by the photographed human body while ensuring the shooting effect.

[0142] In some optional implementations, the second shooting instruction information includes at least one of the following:

[0143] X-ray generator angle adjustment instruction information, X-ray generator position adjustment instruction information, X-ray detector angle adjustment instruction information, X-ray detector position adjustment instruction information, photography distance adjustment instruction information, exposure parameter adjustment instruction information, loading or removing filter grid instruction information, loading or removing filter instruction information, beam limiter opening size adjustment instruction information, X-ray dose adjustment instruction information.

[0144] It is understandable that the values ​​of the key factor indicators corresponding to the machine status can be determined based on clinical application standards or industry experience.

[0145] Exemplarily, the position of the X-ray generator refers to the spatial position of the X-ray generator, including height, horizontal position, etc. The position of the X-ray detector refers to the spatial position of the X-ray generator, including height, horizontal position, etc. The unit of X-ray dose is milliampere / millisecond. The X-ray imaging system can adjust the X-ray dose by adjusting the voltage between the cathode and anode of the X-ray generator, or adjusting the exposure time per unit time. Exposure parameters include aperture parameters, sensitivity parameters, etc.

[0146] It can be understood that the second shooting instruction information can be an automated adjustment instruction content, such as an instruction to adjust the machine status indicator by pressing a button; it can also be a manual adjustment instruction content, such as an instruction to adjust the machine status indicator by manual operation. The embodiment of the present application does not limit this.

[0147] In some optional implementations, the dynamic shooting instruction information also includes first shooting instruction information, and the first shooting instruction information is used to instruct the user to adjust the body state.

[0148] In some embodiments, the shooting position adjustment can be divided into machine state adjustment and human state adjustment. The machine state includes the angle of the X-ray generator, the position of the X-ray generator, the angle of the X-ray detector, the position of the X-ray detector, the shooting distance, the exposure parameters, the presence or absence of a grid, the presence or absence of filtration, the opening size of the beam limiter, the X-ray dose, the height of the bed, etc. The embodiment of the present application implements the instruction of the machine state adjustment through the second shooting instruction information. The human state adjustment includes the posture and position of the person relative to the machine (mainly the flat-panel detector). The embodiment of the present application implements the instruction of the machine state adjustment through the first shooting instruction information, such as instructing the patient to get as close to the flat-panel detector as possible.

[0149] Exemplarily, the X-ray generator angle, X-ray generator position, X-ray detector angle, X-ray detector position, bed height and other information may also be displayed in the second shooting instruction information using icons. For example, the height (vertical distance) or horizontal distance of the X-ray generator may be displayed using a distance line segment with an arrow and a distance value; optionally, as the position of the X-ray generator changes, the length of the distance line segment and the distance value change accordingly. For another example, the angle between the X-ray generator and the bracket may be displayed in the second shooting instruction information using an arc and an angle value; optionally, as the angle of the X-ray generator changes, the length of the arc and the angle value change accordingly.

[0150] The present application not only realizes the indication of the adjustment of the human body state, but also realizes the indication of the adjustment of the machine state, thereby facilitating the technician to position the film according to the shooting instruction information, which can effectively improve the shooting efficiency and imaging quality, and reduce the professional requirements for the technician, thereby saving manpower and material resources.

[0151] In some optional implementations, the first shooting instruction information includes at least one of the following:

[0152] Human body posture adjustment instruction information, human body position adjustment instruction information.

[0153] It can be understood that the human body state adjustment includes the posture and position of the person relative to the machine (mainly the flat-panel detector). The embodiment of the present application implements the instruction of the machine state adjustment through the first shooting instruction information, such as instructing the patient to get as close to the flat-panel detector as possible.

[0154] It can be understood that the third shooting indication information is used to indicate multiple positional relationships; the third shooting indication information used to indicate multiple positional relationships includes a dynamic image stitched together from multiple frame images corresponding to the multiple positional relationships, and the multiple frame images corresponding to the multiple positional relationships include: a global image reflecting the positional relationship between the machine as a whole and the human body to be photographed, a local close-up image reflecting the positional relationship between the X-ray generator and the X-ray detector, and a local close-up image reflecting the positional relationship between the X-ray generator and the human body to be photographed.

[0155] Exemplarily, the positional relationship between the entire machine and the human body to be photographed can be a panoramic image containing the entire machine and the human body to be photographed, so that the user can intuitively understand the orientation information of the entire machine and the human body to be photographed; the positional relationship between the entire machine and the human body to be photographed can also be displayed in the image with an icon, for example, using a distance line segment with an arrow and a distance value to display the distance between the entire machine and the human body to be photographed, and using an arc and an angle value to display the angle between the entire machine and the human body to be photographed. The positional relationship between the X-ray generator and the X-ray detector can facilitate users to intuitively understand the positional relationship between the X-ray generator and the X-ray detector; the positional relationship between the X-ray generator and the X-ray detector can also be displayed in the image with an icon, for example, using a distance line segment with an arrow and a distance value to display the distance between the X-ray generator and the X-ray detector, and using an arc and an angle value to display the angle between the X-ray generator and the X-ray detector. The positional relationship between the X-ray generator and the human body to be photographed may be a close-up image of the X-ray generator and the human body to be photographed, so that the user can intuitively understand the positional information between the X-ray generator and the human body to be photographed; the positional relationship between the X-ray generator and the human body to be photographed may also be displayed in the image using an icon, for example, using a distance line segment with an arrow and a distance value to display the distance between the X-ray generator and the human body to be photographed, and using an arc and an angle value to display the angle between the X-ray generator and the human body to be photographed. Among them, the location of the X-ray generator may be the head part, and the above-mentioned positional relationship involving the X-ray generator may be understood as the relative position between the head part and the X-ray detector or the human body to be photographed, such as the direction and / or angle.

[0156] In some optional implementations, the type of dynamic shooting indication information includes at least one of the following:

[0157] Voice, static images, dynamic pictures, etc.

[0158] It is understandable that the dynamic form of the dynamic shooting instruction information includes a video or a dynamic image composed of multiple frames of images. In some optional embodiments, the dynamic shooting instruction information can be a separate voice, a static image or a dynamic picture, etc., or any combination of the above multiple types. Among them, the dynamic picture can be a dynamic image and a video, the dynamic image can be a PPT slide, and the video is generally continuous and has sound effects.

[0159] Exemplarily, the embodiment of the present application first extracts and quantifies the key factor indicators that affect the filming position according to the shooting position parameters, arranges and combines the key factor indicators, and generates a dynamic positioning instruction animation video (shooting instruction information) under different conditions according to the position parameters. Voice or icons can be added to the video to indicate the accurate position information (head, tablet angle, SID, etc.). The positioning instruction animation is played on a large screen set at the head of the machine to guide the user (such as a technician) to correctly operate to the recommended position. The positioning dynamic instruction animation video can be instructed step by step or displayed in full; the step-by-step content can be triggered by the state of the machine, which will be described in detail later.

[0160] In some optional implementations, the type of dynamic shooting indication information includes a dynamic picture; the form of the dynamic picture includes any one of the following: a video picture, a multi-frame image picture;

[0161] Wherein, when the dynamic picture is in the form of a multi-frame image picture, the dynamic picture is a dynamic image picture composed of the multi-frame image pictures.

[0162] It is understandable that video images are generally continuous and have sound effects; multi-frame images can be PPT slides. Among them, the correspondence between the screen image and the key factor indicator can be one-to-one or many-to-one. For example, each frame of the screen image can correspond to a positioning operation indicating a key factor indicator, and the multi-frame image corresponds to the positioning operation indicating multiple key factor indicators, thereby forming a multi-frame image screen; the multi-frame image can correspond to a positioning operation indicating a key factor indicator, and the multi-frame image corresponds to the positioning operation indicating multiple key factor indicators, thereby forming a multi-frame image screen.

[0163] In some optional implementations, in step S2300, displaying dynamic shooting instruction information includes:

[0164] Step S2301, displaying the dynamic action process or dynamic control process of adjusting from the initial machine state to the target machine state;

[0165] and / or,

[0166] Step S2302, displaying the dynamic action process of adjusting from the initial human body state to the target human body state.

[0167] It is understandable that the content of the dynamic shooting instruction information can be the dynamic action process or dynamic control process of adjusting the initial machine state to the target machine state, or the dynamic action process of adjusting the initial human body state to the target human body state, or the superposition of the two, that is, the dynamic action process or dynamic control process of adjusting the initial machine state to the target machine state, and the superposition of the dynamic action process of adjusting the initial human body state to the target human body state, and the embodiments of the present application do not limit this. Among them, the dynamic action process or dynamic control process of adjusting the initial machine state to the target machine state, and the superposition of the dynamic action process of adjusting the initial human body state to the target human body state can be the superposition of the time dimension (playing in sequence), or the superposition of the space dimension (such as showing the dynamic process of both at the same time in the same dynamic picture).

[0168] Exemplarily, the initial human body state can be a preset human body state. For example, the default human body state corresponds to a posture of a human body standing next to a machine, and the target human body state is a posture in which the center line of the human body is parallel to the body axis of the object being irradiated (in the axial direction). The content of the shooting instruction information shows the dynamic movement process of the X-ray generator from the posture of the human body standing next to the machine to the posture in which the center line of the human body is parallel to the body axis of the object being irradiated (in the axial direction).

[0169] In some optional implementations, the initial machine state is a default machine state; or, the initial machine state is an actual machine state acquired by a machine state sensor at an initial moment.

[0170] It can be understood that the default machine state can be a preset machine state. For example, the corresponding X-ray generator angle in the default machine state is 0 degrees, and the corresponding X-ray generator angle in the target machine state is 30 degrees. The content of the shooting instruction information shows the dynamic movement process or dynamic control process of the X-ray generator angle from 0 degrees to 30 degrees.

[0171] It can be understood that the initial machine state can also be the actual machine state collected by the machine state sensor at the initial moment. For example, at the initial moment, the corresponding X-ray generator angle in the machine state is 25 degrees, and the corresponding X-ray generator angle in the target machine state is 30 degrees. The content of the shooting instruction information shows the dynamic movement process or dynamic control process of the X-ray generator angle from 25 degrees to 30 degrees.

[0172] It is understandable that the current machine state is acquired by a machine state sensor. The machine state sensor may be an angle sensor, a displacement sensor, etc. For example, the machine state sensor may be an angle sensor, and the angle of the X-ray generator corresponding to the current machine state may be acquired by using an angle sensor provided on the X-ray generator to obtain the angle of the X-ray generator corresponding to the current machine state.

[0173] In some optional implementations, in step S2200, generating dynamic shooting instruction information according to the shooting position parameters of the human body includes:

[0174] Step S2210, continuously acquiring the current machine state, where the current machine state is acquired by the machine state sensor;

[0175] Step S2220, obtaining the target machine state according to the body position parameters of the human body;

[0176] Step S2230, generating dynamic shooting instruction information according to the current machine state and the target machine state, and updating the shooting instruction information according to the change of the current machine state;

[0177] Correspondingly, in step S2300, dynamic shooting instruction information is displayed, including:

[0178] Step S2311, displaying shooting instruction information including the current machine state and the target machine state, and updating and displaying dynamic shooting instruction information according to the updated current machine state.

[0179] It is understandable that the dynamic shooting instruction information can be a real-time interactive method, that is, by capturing the current machine status in real time, tracking the user's operation on the machine status, and updating the shooting instruction information in real time as the user operates the machine status.

[0180] Exemplarily, the current machine state obtained in real time can be rendered and displayed in an opaque entity; the target machine state can be rendered and displayed in a transparent or semi-transparent manner; as the user operates the machine state, the entity in the displayed dynamic picture gradually moves toward the transparent or semi-transparent target machine state. For example, the angle of the X-ray generator corresponding to the current machine state is 25 degrees, and the angle of the X-ray generator corresponding to the target machine state is 30 degrees. The content of the shooting instruction information is rendered in an opaque entity to display the X-ray generator at the 25-degree position, and rendered in a transparent frame to display the X-ray generator at the 30-degree position; as the user operates the angle of the X-ray generator, the opaque entity X-ray generator in the dynamic picture gradually moves until it overlaps with the X-ray generator at the 30-degree position of the transparent frame.

[0181] In some optional implementations, in step S2300, displaying dynamic shooting instruction information includes:

[0182] Step S2321, scrolling and playing the shooting instruction information;

[0183] or,

[0184] Step S2322, playing the shooting instruction information once;

[0185] or,

[0186] Step S2323, obtaining a play operation instruction, and starting to play, pausing to play, or stopping to play the shooting instruction information according to the play operation instruction.

[0187] It is understandable that the playback method of dynamic guidance may include but is not limited to: automatic scrolling playback as in step S2321; automatic single playback as in step S2322; manual control of playback, pause, and end as in step S2323.

[0188] In some optional implementations, the dynamic picture includes multiple positioning indication pictures corresponding to multiple positioning key factor indicators, and the positioning indication pictures are in the form of any one of the following: video pictures, single-frame image pictures, and multi-frame image pictures.

[0189] It is understandable that the dynamic picture includes multiple positioning indication pictures (i.e., multiple second shooting indication information) corresponding to multiple positioning key factor indicators. For example, when the positioning indication picture is a video picture, the positioning indication picture is a segment of the video picture, which is used to correspond to the action process or operation process of indicating a positioning key factor indicator. When the positioning indication picture is a single-frame image picture, for example, each frame of the picture image may be a positioning operation corresponding to one key factor indicator, and multiple frames of the picture images correspond to positioning operations indicating multiple key factor indicators, thereby forming a multi-frame image picture. When the positioning indication picture is a multi-frame image picture, the multi-frame image may be a positioning operation corresponding to one key factor indicator, and the multi-frame image corresponds to positioning operations indicating multiple key factor indicators, thereby forming a multi-frame image picture.

[0190] In actual operation, the dynamic shooting instruction information can be provided in steps or displayed in full. The step-by-step instructions can be triggered by the current machine status, which will be further described below.

[0191] In some optional implementations, in step S2300, displaying dynamic shooting instruction information includes:

[0192] Step S2331, obtaining a specific positioning indication picture playback operation instruction;

[0193] Step S2332, displaying a corresponding positioning instruction screen according to the specific positioning instruction screen playback operation instruction.

[0194] The above-mentioned specific positioning instruction screen can be understood as the target second shooting instruction information among the multiple second shooting instruction information. In some embodiments, the user can arbitrarily choose which positioning instruction screen to start playing. For example, according to the user's experience and habits or the need to watch a certain clip repeatedly, the user can operate the specific positioning instruction screen playback operation instruction to make the system display the corresponding positioning instruction screen.

[0195] In some optional implementations, in step S2300, displaying dynamic shooting instruction information includes:

[0196] Step S2340, continuously acquiring the current machine state, where the current machine state is acquired by the machine state sensor;

[0197] Step S2350, displaying the corresponding positioning instruction screen according to the current machine status and preset display rules.

[0198] It is understandable that the content of the step-by-step process can be triggered by the current machine state. Two examples are given below to explain in detail.

[0199] In some optional implementations, in step S2350, according to the current machine state and the preset display rules, the corresponding positioning instruction screen is displayed, including:

[0200] Step S2351, displaying the i-th positioning instruction screen to instruct the user to adjust the i-th positioning key factor indicator, wherein i=1, 2, ..., N, and N is the number of positioning key factor indicators; when the current machine state is that the i-th positioning key factor indicator is adjusted in place, displaying the next positioning instruction screen to instruct the user to adjust the next positioning key factor indicator;

[0201] or,

[0202] Step S2352, obtain multiple current machine states corresponding to multiple positioning key factor indicators; determine whether the current machine state has reached the target machine state; based on the determination result, obtain the positioning key factor indicators that have not reached the target machine state; display the positioning indication screen corresponding to the positioning key factor indicators that have not reached the target machine state, wherein each positioning key factor indicator corresponds to a current machine state and a target machine state.

[0203] It is understandable that the preset display rule corresponding to step S2351 can be summarized as: display a positioning indication screen corresponding to a positioning key factor indicator, obtain the corresponding adjustment status of the positioning key factor indicator, and when the positioning key factor indicator is adjusted, display the positioning indication screen corresponding to the next positioning key factor indicator, and so on. In this way, it is convenient for technicians to make gradual adjustments and reduce the requirements for technicians' skills.

[0204] For example, the dynamic shooting instruction information can be made into a wizard-style, which sequentially instructs the adjustment of the X-ray generator angle, X-ray generator position, X-ray detector angle, X-ray detector position, shooting distance, exposure parameters, whether there is a grid, whether there is filtering, the opening size of the beam limiter, X-ray dose, etc. When i=1, the first positioning instruction screen is played as the X-ray generator angle adjustment instruction screen, and the X-ray generator angle adjustment status is continuously obtained; after the X-ray generator angle adjustment is completed, let i=2, and the second positioning instruction screen is automatically played as the X-ray generator position adjustment instruction screen, and the X-ray generator position adjustment status is continuously obtained... and so on, until all the key positioning factor indicators are adjusted.

[0205] It is understandable that the preset display rule corresponding to step S2352 can be summarized as: displaying the positioning indication screen corresponding to the positioning key factor indicators that have not reached the target machine state. That is, first determine which of the current machine states are in place (i.e., no adjustment is required) and which are not in place (i.e., adjustment is required), and then display the positioning indication screen for those that are not in place. In this way, it is convenient for technicians to directly adjust the positioning key factor indicators that are not in place, saving time for positioning adjustment.

[0206] In some optional implementations, the key positioning factor indicators include:

[0207] Machine state indicators; or, machine state indicators and human state indicators;

[0208] in,

[0209] The machine status indicator includes at least one of the following:

[0210] X-ray generator angle, X-ray generator position, X-ray detector angle, X-ray detector position, photographic distance, exposure parameters, presence or absence of grid, presence or absence of filtration, beam limiter opening size, X-ray dose;

[0211] The human body state index includes at least one of the following: human body posture and human body position.
