[0029] Figure 1 is a medical imaging system 100 according to an embodiment of the present application. Figure 1As shown, the medical imaging system 100 includes a suspension device 110, a wall stand device 120, and a detection bed device 130 arranged in a scanning room 101, and a control device 150 arranged in a control room 102. The suspension device 110 includes a longitudinal guide rail 111, a transverse guide rail 112, a telescopic cylinder 113, a trolley 114, and a tube assembly 115.

[0030] Although some embodiments of the present application are described based on a suspended X-ray imaging system, the embodiments of the present application are not limited thereto.

[0031] For ease of description, in the present application, the x-axis, y-axis and z-axis are defined as the x-axis and y-axis are located in a horizontal plane and are perpendicular to each other, and the z-axis is perpendicular to the horizontal plane. Specifically, the direction of the longitudinal guide rail 111 is defined as the x-axis, the direction of the transverse guide rail 112 is defined as the y-axis direction, and the extension direction of the retractable cylinder 113 is defined as the z-axis direction, and the z-axis direction is the vertical direction.

[0032] The longitudinal guide rail 111 and the transverse guide rail 112 are vertically arranged, wherein the longitudinal guide rail 111 is installed on the ceiling, and the transverse guide rail 112 is installed on the longitudinal guide rail 111. The telescopic cylinder 113 is used to carry the ball tube assembly 115.

[0033] The pulley 114 is arranged between the transverse guide rail 112 and the telescopic cylinder 113. The pulley 114 may include a rotating shaft, a motor, a reel and other components. The motor can drive the reel to rotate around the rotating shaft, thereby driving the telescopic cylinder 113 to move along the z-axis and / or slide relative to the transverse guide rail. The pulley 114 can slide relative to the transverse guide rail 112, that is, the pulley 114 can drive the telescopic cylinder 113 and / or the ball tube assembly 115 to move along the y-axis direction. And the transverse guide rail 112 can slide relative to the longitudinal guide rail 111, thereby driving the telescopic cylinder 113 and / or the ball tube assembly 115 to move along the x-axis direction.

[0034] The telescopic cylinder 113 includes a plurality of cylinders with different inner diameters, and the plurality of cylinders can be sequentially sleeved in the cylinder located above them from bottom to top to achieve telescoping. The telescopic cylinder 113 can be telescopic (or movable) in the vertical direction, that is, the telescopic cylinder 113 can drive the ball tube assembly to move along the z-axis direction. The lower end of the telescopic cylinder 113 is also provided with a rotating part, which can drive the ball tube assembly 115 to rotate.

[0035] The tube assembly 115 includes an X-ray tube that can generate X-rays and project X-rays to a desired region of interest ROI of the patient. Specifically, the X-ray tube can be positioned adjacent to a beam limiter that is used to align the X-rays to the desired region of interest of the patient. At least a portion of the X-rays can be attenuated by the patient and can be incident on the detector 121 / 131.

[0036] The suspension device 110 further includes a beam limiter 117, which is usually installed below the X-ray tube. The X-rays emitted by the X-ray tube are irradiated onto the object to be inspected through the opening of the beam limiter 117. The size of the opening of the beam limiter 117 determines the irradiation range of the X-rays, that is, the size of the exposure field of view (FOV). The lateral position of the X-ray tube and the beam limiter 117 determines the position of the exposure field of view FOV on the object to be inspected. It is well known that X-rays are harmful to the human body, so it is necessary to control the X-rays so that they only irradiate the part of the object to be inspected that needs to be inspected, that is, the region of interest (ROI).

[0037] The suspension device 110 further includes a tube control device (console) 116, which is installed on the tube assembly. The tube control device 116 includes a user interface such as a display screen and control buttons for performing pre-shooting preparations, such as patient selection, protocol selection, and positioning.

[0038] The movement of the suspension device 110 includes the movement of the tube assembly along the x-axis, y-axis and z-axis, and the rotation of the tube assembly in the horizontal plane (the rotation axis is parallel to or coincident with the z-axis) and in the vertical plane (the rotation axis is parallel to the y-axis). In the above-mentioned movement, a motor is usually used to drive the corresponding component to rotate and thus achieve the corresponding movement or rotation, and the corresponding control component is generally installed in the pulley 114. The X-ray imaging unit further includes a motion control unit (not shown in the figure), which can control the above-mentioned movement of the suspension device 110. Further, the motion control unit can receive a control signal to control the corresponding component to perform a corresponding movement.

[0039] The column device 120 includes a first detector assembly 121, a column 122 and a connecting portion 123. The connecting portion 123 includes a support arm connected perpendicularly to the height direction of the column 122 and a rotating bracket installed on the support arm. The first detector assembly 121 is installed on the rotating bracket. The column device 120 further includes a detector driving device arranged between the rotating bracket and the first detector assembly 121. Under the drive of the detector driving device, the first detector assembly 121 moves along a direction parallel to the height direction of the column 122 on the plane supported by the rotating bracket. The first detector assembly 121 can also be further rotated relative to the support arm to form a certain angle with the column. The first detector assembly 121 has a plate-like structure, and its direction is variable so that the X-ray incident surface becomes vertical or horizontal according to the incident direction of the X-ray.

[0040] The detection bed device 130 includes a second detector assembly 131. The selection or use of the first detector assembly 121 and the second detector assembly 131 can be determined based on the patient's shooting part and / or shooting protocol, and can also be determined based on the position of the object to be detected obtained by camera shooting, so as to perform shooting inspections in the supine or standing position. Figure 1 Only an example diagram of the column and the detection bed is shown. Those skilled in the art should understand that columns and / or detection beds of any form or arrangement may be selected, or only columns may be installed. The columns and / or detection beds do not limit the entire scheme of the present application.

[0041] In some embodiments, the medical imaging system includes a camera 140 (e.g., a camera), which can be used to capture the detected object to obtain a captured image containing the detected object, such as a static optical image or a series of frame optical images in a dynamic real-time video stream, to assist in positioning and exposure settings, etc. The camera can be installed on a suspension device, such as on the side of the beam limiter 117, etc., and the embodiments of the present application are not limited to this. The camera 140 includes one or more cameras, such as a digital camera, an analog camera, etc., or a depth camera, an infrared camera, or an ultraviolet camera, etc., or a 3D camera, a 3D scanner, etc., or a red, green, and blue (RGB) sensor, an RGB depth (RGB-D) sensor, or other devices that can capture color image data of a target object.

[0042] In some embodiments, the control device 150 may include a source controller and a detector controller. The source controller is used to command the X-ray source to emit X-rays for image exposure. The detector controller is used to select a suitable detector from a plurality of detectors and coordinate the control of various detector functions, for example, automatically selecting a corresponding detector according to the position or posture of the object to be detected, or performing various signal processing and filtering functions, specifically, for initial adjustment of the dynamic range, interleaving of digital image data, etc. In some embodiments, the control device may provide power and timing signals for controlling the operation of the X-ray source and the detector.

[0043] In some embodiments, the control device may also be configured to use the digitized signals to reconstruct one or more desired images and / or determine useful diagnostic information corresponding to the patient, wherein the control device may include one or more dedicated processors, graphics processing units, digital signal processors, microcomputers, microcontrollers, application specific integrated circuits (ASICs), field programmable gate arrays (FPGAs), or other appropriate processing devices.

[0044] Of course, the medical imaging system may also include other numbers or configurations or forms of control devices, for example, the control device may be local (e.g., co-located with one or more medical imaging systems 100, such as in the same facility and / or the same local network); in other implementations, the control device may be remote and therefore only accessible via a remote connection (e.g., via the Internet or other available remote access technology). In a specific implementation, the control device may also be configured in a cloud-like manner and may be accessed and / or used in a manner substantially similar to accessing and using other cloud-based systems.

[0045] The system 100 also includes a storage device (not shown), and the processor can store the digitized signal in the storage. For example, the storage can include a hard disk drive, a floppy disk drive, a CD-ROM read / write drive, a digital universal disk drive, a flash drive, and / or a solid-state memory. The storage can also be integrated with the processor to effectively use the floor space and / or meet the expected imaging requirements.

[0046] The system 100 also includes an input device 160, which may include a form of operator interface such as a keyboard, a mouse, a voice-activated control device, a touch screen (which may also serve as a display device described later), a trackball, or any other suitable input device. The operator may input operation signals / control signals to the control device through the input device.

[0047] The system 100 also includes a display device 151 (such as a touch screen or a display screen), which can be used to display an operation interface such as a list of detected objects, a position or exposure setting of the detected objects, and an image of the detected objects.

[0048] Usually, the size of the obtained medical image is generally equal to the size of the detector (exposure field of view). If the region of interest is within the size of the detector (exposure field of view), the entire region of interest can be fully presented in one image. If the region of interest exceeds the size of the detector (exposure field of view), the entire region of interest cannot be presented in one image, which requires dividing the region of interest into multiple regions, exposing and imaging each region separately, and stitching the multiple X-ray images together to obtain a complete medical image. In the following, the images obtained by X-ray imaging of each region are referred to as sub-medical images, and the completed medical image is also referred to as a combined image or a stitched image.

[0049] At present, each sub-medical image is obtained by being exposed independently, that is, for each sub-medical image, its exposure parameters are independently set, and exposure is performed according to the set exposure parameters to obtain each sub-medical image. The embodiment of the present application proposes a medical imaging method and a medical imaging system, which enables an operator to intuitively view or adjust the exposure parameters of all sub-medical images, which can simplify operations and improve efficiency.

[0050] The following is a detailed description of the embodiments of the present application.

[0051] The embodiment of the present application proposes a medical imaging system, the system comprising: an imaging device, a display device, and a control device, the imaging device comprising an X-ray source and a detector, the X-ray source and the detector being able to cooperate to obtain a medical image of a detected object, the medical image being composed of a first number (N) of sub-medical images spliced ​​together, the first number being greater than or equal to 2; a display device, which displays a graphical user interface including a parameter setting display window. A control device, which performs exposure according to the set exposure parameters of each sub-medical image, and generates the medical image by splicing the first number of sub-medical images after exposure. The first number N can be determined according to the size of the exposure area and the size of the detector, for example, the height direction of the detector is H, the length of the exposure area is W, the first number N is an integer greater than or equal to W / H, or when determining the first number, it is also necessary to consider the distance from the detector to the region of interest, the distance from the focus to the detector, and the size of the overlapping portion of two adjacent sub-medical images when splicing the sub-medical images, for details, reference can be made to the relevant technology, and the embodiment of the present application is not limited thereto. For example, when the first number is 5, that is, 5 sub-medical images need to be exposed, and the final medical image is obtained by splicing the 5 sub-medical images. The serial numbers of the 5 sub-medical images are #1, #2, #3, #4, and #5. The serial numbers can also correspond to the order of exposure of the sub-medical images, that is, after the exposure parameters of each sub-medical image are set, the sub-medical images are exposed in sequence according to the order of their serial numbers, that is, the first sub-medical image to be exposed is the sub-medical image with serial number #1. After the exposure is completed, the second sub-medical image to be exposed is the sub-medical image with serial number #2, and so on, until the exposure of all the sub-medical images is completed.

[0052] For the implementation of the imaging device, display device, and control device, reference can be made to the aforementioned Figure 1 The corresponding embodiments will not be described in detail, and the differences are described in detail below.

[0053] Figure 2 is a schematic diagram of a graphical user interface displayed by a display device according to an embodiment of the present application, such as Figure 2As shown, the graphical user interface 200 includes a parameter setting display window 201, and the parameter setting display window 201 simultaneously displays the exposure parameters of each sub-medical image in the first number of sub-medical images. In other words, the operator can intuitively view the exposure parameters of all sub-medical images in the window of the same interface without switching windows or interfaces, which simplifies the operation, and the exposure parameters of each sub-medical image can be intuitively compared and displayed.

[0054] In some embodiments, the parameter setting display window 201 includes a parameter list 2011, the parameter list 2011 includes the first number of rows, different rows of the parameter list respectively display exposure parameters of different sub-medical images, and one row of the parameter list includes a serial number corresponding to a sub-medical image and the exposure parameters of the sub-medical image. The exposure parameters include at least one of tube voltage, tube current, milliampere-seconds, exposure time, and automatic exposure control ionization chamber. Wherein, the medical imaging system may include multiple (Z) automatic exposure control ionization chambers (for example, arranged in a detector), the multiple automatic exposure control ionization chambers may be distributed at different positions of the detector, the X-ray tube may generate X-rays, the automatic exposure control ionization chamber may detect the amount of X-rays received after passing through the detected object, if the amount of X-rays exceeds a predetermined amount, the automatic exposure control ionization chamber may send a notification signal to the control device, and the control device may stop the irradiation of X-rays, thereby adjusting the amount of X-rays emitted via the automatic exposure control ionization chamber. Before exposure, the automatic exposure control ionization chamber at a position corresponding to the position of the region of interest may be selected or set for automatic exposure control.

[0055] In some embodiments, the list represents the corresponding exposure parameters in the form of numerical values, characters, or graphic objects. For example, the tube voltage, tube current, milliampere-seconds, and exposure time can be displayed as numerical values, indicating the size of the corresponding exposure parameters, and the automatic exposure control ionization chamber can be displayed as characters (such as L, M, R) or as graphic objects (such as rectangular boxes), and the characters or the graphic objects represent the automatic exposure control ionization chamber selected by the operator, that is, indicating which automatic exposure control ionization chamber among the Z automatic exposure control ionization chambers is used for exposure control.

[0056] like Figure 2As shown, the first number M=5, the exposure parameters include tube voltage (KV), tube current (mA), milliampere-seconds (mAs), exposure time (ms), and automatic exposure control ionization chamber (Ion-Chamber), and the parameter list 2011 includes 5 rows, and different rows of the parameter list respectively display the exposure parameters of different sub-medical images. The first row of the parameter list includes the serial number #1 of the sub-medical image with the serial number #1 and the exposure parameters corresponding to the sub-medical image, the second row of the parameter list includes the serial number #2 of the sub-medical image with the serial number #2 and the exposure parameters corresponding to the sub-medical image, the third row of the parameter list includes the serial number #3 of the sub-medical image with the serial number #3 and the exposure parameters corresponding to the sub-medical image, the fourth row of the parameter list includes the serial number #4 of the sub-medical image with the serial number #4 and the exposure parameters corresponding to the sub-medical image, and the fifth row of the parameter list includes the serial number #5 of the sub-medical image with the serial number #5 and the exposure parameters corresponding to the sub-medical image.

[0057] In some embodiments, the initial value of the exposure parameter of each sub-medical image displayed in the parameter setting display window is a default value (the numerical value is a default size or the character or graphic object is a default character or graphic object, and the numerical value is taken as an example below). The default values ​​of the exposure parameters of each sub-medical image may be the same or different. The embodiments of the present application are not limited to this. The default value may be any value, for example, the default value may be the maximum value, minimum value or average value of the numerical range of the exposure parameter; or the default value is related to one or more of the following: the anatomical position to be imaged, the size of the object to be detected (the size of the object to be detected may include thickness information of the object to be detected), the distance from the X-ray source to the detector, the field of view of the imaging device, the automatic exposure control ionization chamber mode, the focal spot size, and the configuration of the filter grid.

[0058] In some embodiments, the control device may use artificial intelligence algorithms (such as deep learning networks), standard scanning protocol libraries, databases or lookup tables (LUTs) and other methods to calculate the recommended exposure parameter values ​​for each sub-medical image based on the above-mentioned factors related to the default values ​​(such as the size of the object to be detected, the distance from the X-ray source to the detector, etc.), as default values, and the initial value of the exposure parameter of each sub-medical image displayed in the parameter setting display window is the recommended exposure parameter. The above-mentioned recommended exposure parameter values ​​are used as the set exposure parameters, so the operator does not need to adjust the exposure parameters, and the control device can expose each sub-medical image according to the above-mentioned recommended exposure parameter values. The implementation of the artificial intelligence algorithm can refer to the relevant technology, and the embodiments of the present application are not limited thereto.

[0059] In some embodiments, the operator can also adjust the default value of the exposure parameter initially displayed in the parameter setting display window, and use the adjusted exposure parameter value as the set exposure parameter, and the control device can expose each sub-medical image according to the adjusted exposure parameter value. The following describes how to adjust the exposure parameter value.

[0060] In some embodiments, the system may include: an input device that receives a second input operation for adjusting exposure parameters of a second number of sub-medical images in the first number (Q) of sub-medical images; the second number is greater than or equal to 1 and less than or equal to the first number; and the control device performs exposure according to the exposure parameters of each sub-medical image adjusted by the second input operation. That is, the operator can adjust the exposure parameters of one or more sub-medical images at the same time.

[0061] In some embodiments, when the second number is 1, the exposure parameter corresponding to one sub-medical image is adjusted, and the exposure parameter of the sub-medical image displayed in the parameter setting display window is updated in real time to the adjusted exposure parameter. That is, the second input operation adjusts the exposure parameter of only one sub-medical image, and the exposure parameters of other sub-medical images are not adjusted. When the exposure parameter of the sub-medical image is adjusted by the second input operation, the parameter setting display window synchronously displays the adjusted exposure parameter. When the exposure parameters of multiple sub-medical images need to be adjusted, the operator can adjust the exposure parameters of each sub-medical image one by one according to the second input operation, that is, the exposure parameters of one sub-medical image can be adjusted by executing the second input operation. If the exposure parameters of multiple sub-medical images need to be adjusted, the second input operation needs to be executed for different sub-medical images respectively, and the exposure parameters of each of the multiple sub-medical images are adjusted respectively.

[0062] In some embodiments, when the second number is greater than 1, the exposure parameters of the second number of sub-medical images are adjusted simultaneously, and the exposure parameters of the second number of sub-medical images displayed in the parameter setting display window are updated in real time to the adjusted exposure parameters. That is, the second input operation adjusts the exposure parameters of the Q sub-medical images, and when the second input operation adjusts the exposure parameters of the Q sub-medical images, the parameter setting display window synchronously displays the adjusted exposure parameters. That is, the second input operation can adjust the exposure parameters of the Q sub-medical images at the same time, thereby further simplifying the operation and steps of adjusting the parameters and saving the parameter adjustment time.

[0063] In some embodiments, optionally, the input device further receives a first input operation for selecting the second number of sub-medical images, first determines Q sub-medical images of the first number of sub-medical images whose exposure parameters need to be adjusted through the first input operation, and then adjusts the exposure parameters of the selected Q sub-medical images through a second input operation. Figure 2 As shown, by clicking the selection box 31 corresponding to the row where the Q sub-medical images whose exposure parameters need to be adjusted are located in the parameter list 2011, or clicking any position in the row, the row where the selected Q sub-medical images are located can be highlighted. Alternatively, it is also possible to directly adjust the exposure parameters of the Q sub-medical images through the second input operation without first selecting the Q sub-medical images through the first input operation, and the embodiment of the present application is not limited thereto.

[0064] In some embodiments, the graphical user interface further includes a parameter adjustment mark corresponding to the exposure parameter. When the second input operation triggers the parameter adjustment mark, the exposure parameters of the Q sub-medical images displayed in the parameter setting display window are updated in real time to the adjusted exposure parameters. The parameter adjustment mark may be one or more, that is, for multiple exposure parameters, the same parameter adjustment mark may be shared to adjust the exposure parameter value, or different parameter adjustment marks may be set for different exposure parameters to adjust the exposure parameter value. The parameter adjustment mark may be located next to the corresponding exposure parameter in the aforementioned parameter list 2011, or the graphical user interface may further include a parameter adjustment window, and the parameter adjustment mark may be located in the parameter adjustment window. The embodiment of the present application is not limited thereto. The parameter adjustment mark includes a virtual button or other graphic object, and the second input operation for triggering includes clicking the corresponding mark by moving the cursor. The above click and the click described later include touch screen click or mouse click (long press or short press), etc. The embodiment of the present application is not limited thereto.

[0065] like Figure 2 As shown, the graphical user interface also includes a parameter adjustment window 202, which includes a parameter adjustment mark 2021 corresponding to the exposure parameter tube voltage, a parameter adjustment mark 2022 corresponding to the exposure parameter tube current, and a parameter adjustment mark 2023 corresponding to the exposure parameter milliampere second. The parameter adjustment mark 2021 is used as an example for explanation below, and the implementation methods of the parameter adjustment marks 2022 and 2023 are similar to that of the parameter adjustment mark 2021.

[0066] In some embodiments, the parameter adjustment mark 2021 includes a first increase mark 41 and a first decrease mark 42. When the second input operation triggers the first increase mark 41, the exposure parameters of the Q sub-medical images are simultaneously increased by a first value or magnified by a first value multiple. When the second input operation triggers the first decrease mark 42, the exposure parameters of the Q sub-medical images are simultaneously reduced by a second value or reduced by a second value multiple.

[0067] In some embodiments, optionally, the parameter adjustment mark 2021 also includes a second increase mark 43 and a second decrease mark 44. When the second input operation triggers the second increase mark 43, the exposure parameters of the Q sub-medical images are simultaneously increased by a third value or magnified by a third value times. When the second input operation triggers the second decrease mark 44, the exposure parameters of the Q sub-medical images are simultaneously reduced by a fourth value or reduced by a fourth value times. The third value is different from the first value, and the fourth value is different from the second value. For example, the third value is smaller than the first value, and the fourth value is smaller than the second value. Thus, the exposure parameters can be coarsely adjusted through the first increase mark 41 and the first decrease mark 42, and the exposure parameters can be fine-tuned through the second increase mark 43 and the second decrease mark 44, so that the adjustment of the exposure parameters is more flexible.

[0068] In some embodiments, when Q is 1, the second input operation is used to adjust the absolute value of the exposure parameter of one sub-medical image; when Q is greater than 1, the second input operation is used to adjust the relative change value of the exposure parameter of the second number of sub-medical images. Figure 3 is another schematic diagram of a graphical user interface of an embodiment of the present application, such as Figure 2 and Figure 3 As shown, the graphical user interface also includes an adjustment display window 45 corresponding to the parameter adjustment mark. When Q=1 and the second input operation triggers the parameter adjustment mark, the adjustment display window 45 displays the absolute value of the adjusted exposure parameter of the one sub-medical image; for example, Figure 3 As shown, in the current parameter list, for the selected sub-medical image #1, the tube voltage is 80KV. When the second input operation triggers the first increase mark 41, the tube voltage of the sub-medical image #1 increases by a first value (10KV), and the adjustment display window 45 is updated to 90KV. In addition, the tube voltage of the sub-medical image #1 in the parameter list is also updated to 90KV. When the second input operation triggers the second increase mark 43, the tube voltage of the sub-medical image #1 increases by a third value (1KV), and the adjustment display window 45 is updated to 91KV. In addition, the tube voltage of the sub-medical image #1 in the parameter list is also updated to 91KV.

[0069] In some embodiments, when Q is greater than 1 and the second input operation triggers the parameter adjustment mark, the adjustment display window 45 displays the relative change value of the exposure parameter of the Q sub-medical images, for example, when the second input operation triggers the first increase mark, the adjustment display window displays the first value; or, when the second input operation triggers the second increase mark, the adjustment display window displays the third value; or, when the second input operation triggers the first decrease mark, the adjustment display window displays the second value; or, when the second input operation triggers the second decrease mark, the adjustment display window displays the fourth value. Optionally, when Q is greater than 1, the adjustment display window 45 also displays an image mark 451 indicating the corresponding adjustment operation type, and the adjustment operation type includes increasing (for example, represented by a graphic object +) or decreasing (for example, represented by a graphic object -) or zooming in (for example, represented by a graphic object ×) or zooming out (for example, represented by a graphic object ÷). For example, Figure 2 As shown, in the current parameter list, for the selected sub-medical images #1, #3, and #5, the tube voltages are 80KV, 85KV, and 85KV respectively. When the second input operation triggers the first increase mark 41, the tube voltages of the sub-medical images #1, #3, and #5 are simultaneously increased by a first value (10KV), and the adjustment display window 45 is displayed as +10KV. In addition, the tube voltage of the sub-medical image #1 in the parameter list is also updated to be displayed as 90KV, 95KV, and 95KV. When the second input operation triggers the second increase mark 43, the tube voltages of the sub-medical images #1, #3, and #5 are simultaneously increased by a third value (1KV), and the adjustment display window 45 is displayed as +1KV. In addition, the tube voltages of the sub-medical images #1, #3, and #5 in the parameter list are also updated to be displayed as 91KV, 96KV, and 96KV.

[0070] In the above embodiment, the parameter adjustment mark is located in the parameter adjustment window 202 as an example for description, but the embodiment of the present application is not limited to this. Figure 4 is another schematic diagram of a graphical user interface of an embodiment of the present application, such as Figure 4As shown, the parameter adjustment mark 2021 may also be located next to the corresponding exposure parameter in the aforementioned parameter list 2011. When the second input operation triggers the corresponding parameter adjustment mark, the exposure parameter next to the parameter adjustment mark is adjusted. In this scenario, it is not necessary to select Q sub-medical images through the first input operation, and the exposure parameter can be adjusted directly through the second input operation. For example, when the cursor is moved to the vicinity of the exposure parameter through the second input operation, the parameter adjustment mark is displayed next to the exposure parameter, and when the cursor is moved away from the vicinity of the exposure parameter, the parameter adjustment mark is not displayed. Alternatively, the graphical user interface may not include the parameter adjustment mark, and the second input operation includes typing, and the new exposure parameter value is typed in the corresponding exposure parameter in the parameter list through the second input operation to complete the adjustment of the exposure parameter. Examples are not given one by one here.

[0071] In some embodiments, the exposure parameter of the sub-medical image is limited by an upper limit and a lower limit. When the exposure parameter of the sub-medical image exceeds the upper limit or is less than the lower limit after the second input operation is adjusted, the exposure parameter of the sub-medical image displayed in the parameter setting display window is updated to the upper limit or the lower limit. That is, when the exposure parameter of the sub-medical image exceeds the upper limit or is less than the lower limit after the second input operation is adjusted, the exposure parameter adjustment corresponding to the second input operation will be ignored, and the control device and the parameter setting display window will no longer respond to the second input operation to change the exposure parameter. The control device pre-sets the upper limit and lower limit of the exposure parameter of each sub-medical image, and the control device compares the relationship between the adjusted exposure parameter and the upper limit. When the adjusted exposure parameter value is greater than the upper limit, the exposure parameter of the sub-medical image displayed in the parameter setting display window is updated to the upper limit, or the control device compares the relationship between the adjusted exposure parameter and the lower limit. When the adjusted exposure parameter value is less than the lower limit, the exposure parameter of the sub-medical image displayed in the parameter setting display window is updated to the lower limit. For example, for the exposure parameter tube voltage, the upper limit value is pre-set to 200KV and the lower limit value is pre-set to 20KV. Sub-medical images #1 and #3 are selected as the exposure parameters to be adjusted simultaneously. The tube voltage of the current sub-medical image #1 is 195KV, and the tube voltage of the sub-medical image #3 is 185KV. When the second input operation adjusts the tube voltage by 10KV, the adjusted tube voltage of the sub-medical image #1 should be 205KV, which is greater than the upper limit value of 200KV. Therefore, the exposure parameter of the sub-medical image displayed in the parameter setting display window will not be updated to 205KV, but will be updated to 200KV. The adjusted tube voltage of the sub-medical image #3 should be 195KV, which is less than the upper limit value of 200KV. Therefore, the exposure parameter of the sub-medical image displayed in the parameter setting display window is updated to 195KV.

[0072] In some embodiments, the upper limit and lower limit of the exposure parameter can be set as needed. Optionally, the upper limit and lower limit of the exposure parameter can be related to the set focal spot size. Among them, the X-ray focal spot size of the medical imaging system can be divided into micro focal spot, small focal spot, conventional focal spot, large focal spot, etc. For example, a small focal spot is usually defined as between 0.1 mm and 0.6 mm, and a large focal spot is between 0.6 mm and 1.8 mm. Different upper and lower limits can be set for focal spots of different sizes. For example, for the exposure parameter tube voltage, when the focal spot is small, the upper limit is set to 300KV, and when the focal spot is large, the upper limit is set to 400KV. Examples are not given one by one here.

[0073] In some embodiments, Figure 2 and 3 As shown, the graphical user interface also includes a focus adjustment mark 51 (virtual button or other graphic object). When the input device receives a fourth input operation that triggers the focus adjustment mark, the size of the focus can be switched. For example, the fourth input operation for triggering includes clicking the corresponding mark by moving the cursor. When the current focus is a small focus, when the fourth input operation is received, it can be switched to a large focus. When the current focus is a large focus, when the fourth input operation is received, it can be switched to a small focus. The embodiment of the present application is not limited to this. For example, when the current focus is a small focus, when the fourth input operation is received, it can be switched to a regular focus. When the fourth input operation is received again, it can be switched to a large focus. When the fourth input operation is received again, it can be switched to a small focus, etc., which are not exemplified one by one here. In addition, in the focus adjustment mark 51, the graphic object styles of the marks corresponding to different focus sizes can be different.

[0074] In some embodiments, the upper limit value or the lower limit value of the aforementioned exposure parameter is the upper limit value or the lower limit value corresponding to the adjusted focal spot; and when there is an exposure parameter of the sub-medical image in the parameter setting display window that exceeds the adjusted upper limit value or is less than the adjusted lower limit value, the exposure parameter of the sub-medical image displayed in the parameter setting display window is updated to the adjusted upper limit value or the adjusted lower limit value. For example, for the exposure parameter tube voltage, the upper limit value corresponding to the small focal spot is preset to be 200KV, and the upper limit value corresponding to the large focal spot is preset to be 300KV. The currently set tube voltage is 295KV, and when the current setting is a large focal spot, when the tube voltage is increased by 10KV in the second input operation, the adjusted tube voltage should be 305KV, which is greater than the upper limit value 300KV. Therefore, the tube voltage of the sub-medical image displayed in the parameter setting display window will not be updated to 305KV, but updated to 300KV. However, if the fourth input operation is received at this time, when switching to a small focal spot, the tube voltage of the sub-medical image displayed in the parameter setting display window is updated to 200KV. The above takes adjusting the exposure parameters of one medical sub-image as an example. The implementation method for adjusting the exposure parameters of multiple medical sub-images at the same time is similar and will not be described in detail here.

[0075] In some embodiments, Figure 2 and 3 As shown, the graphical user interface also includes an exposure parameter reset mark 61 (virtual button or other graphic object). When the input device receives a third input operation that triggers the exposure parameter reset mark, the exposure parameters of the first number of sub-medical images displayed in the parameter setting display window are all updated to default values; or the exposure parameters of the second number of sub-medical images displayed in the parameter setting display window are updated to default values. When the second number is equal to 1 and the third input operation triggers the exposure parameter reset mark, the exposure parameters of a corresponding sub-medical image are reset, and the exposure parameters of the sub-medical image displayed in the parameter setting display window are updated to default values; or, when the second number is greater than 1 and the third input operation triggers the exposure parameter reset mark, the exposure parameters of the second number of sub-medical images are reset at the same time, and the exposure parameters of the second number of sub-medical images displayed in the parameter setting display window are updated to default values. For example, the third input operation for triggering includes moving the cursor and clicking a corresponding mark. When the third input operation is received, the exposure parameters of all sub-medical images are restored to the default values; or when Q=1, the exposure parameters of only one selected sub-medical image are restored to the default values; or when Q is greater than 1, the exposure parameters of the selected Q sub-medical images are restored to the default values. Thus, when the operator incorrectly adjusts the exposure parameters, the initial settings can be quickly restored.

[0076] In the above examples, the exposure parameter is the tube voltage. The adjustment methods for other exposure parameters, such as tube current, milliampere-seconds, and exposure time are similar, and no further examples are given here. Among them, for the exposure time, since milliampere-seconds is equal to tube current × exposure time ÷ 1000, after setting the tube current, the exposure time can also be adjusted by adjusting milliampere-seconds, and the embodiments of the present application are not limited to this.

[0077] In some embodiments, the medical imaging system may further include a camera device, which photographs the object to be detected to obtain a photographed image containing the object to be detected. In addition, the photographed image obtained by photographing the object to be detected by the camera device can be displayed on a display device. The photographed image is different from the medical image obtained by performing X-ray imaging. The photographed image is used to assist in positioning or exposure setting. For example, assisting in positioning or exposure setting includes obtaining information about the object to be detected, obtaining a shooting protocol, determining shooting dose, posture and other information, and performing positioning based on the shooting protocol, as well as setting the size and position of the exposure area.

[0078] Figure 5 is another schematic diagram of a graphical user interface of an embodiment of the present application, such as Figure 5 As shown, the graphical user interface may also include an area 203 for displaying the captured image. After Q sub-medical images are selected, the switch status marks of multiple (Z) automatic exposure control ionization chambers corresponding to the Q sub-medical images are superimposed and displayed at the positions of the corresponding sub-medical images in the captured image. By triggering the switch status marks, the states of the respective automatic exposure control ionization chambers corresponding to the Q sub-medical images are set to be on or off; and the states of the respective automatic exposure control ionization chambers corresponding to each sub-medical image are simultaneously displayed in the parameter setting display window. Wherein, for each sub-medical image, the marks of the Z automatic exposure control ionization chambers are superimposed and displayed respectively, and the superimposed display positions do not represent their actual positions, but only represent the relative positions of the Z automatic exposure control ionization chambers. Wherein, a rectangular frame can be used as a mark of an automatic exposure control ionization chamber, or different graphic objects can be used as marks of different automatic exposure control ionization chambers, and the embodiments of the present application are not limited thereto.

[0079] like Figure 5 As shown, taking Z=3 as an example, three automatic exposure control ionization chambers are represented by three rectangular frames, which are schematically superimposed on the captured image, as shown in FIG. Figure 5 As shown, Q=1, therefore, three marks (three rectangular frames) of the automatic exposure control ionization chamber are superimposed and displayed at the position corresponding to the first sub-medical image in the captured image. Figure 6This is another schematic diagram of the graphical user interface of the embodiment of the present application, Q=3, therefore, three marks (3 rectangular frames) of the automatic exposure control ionization chamber are superimposed and displayed at the position corresponding to each sub-medical image in the captured image. Figure 7 and Figure 8 is a schematic diagram of a graphical user interface of an embodiment of the present application, and Figure 5 and Figure 6 The difference is that the automatic exposure control ionization chambers are marked with different letters. Taking M=3 as an example, the three automatic exposure control ionization chambers are marked with R, M, and L respectively.

[0080] In some embodiments, the display device also needs to superimpose and display the switch states of Z automatic exposure control ionization chambers corresponding to the selected one or more sub-medical images on the captured image, wherein the on state or off state can be distinguished by the change in the style of the mark of the aforementioned automatic exposure control ionization chamber. The switch state does not indicate the current switch state of the automatic exposure control ionization chamber, but indicates the switch state of the automatic exposure control ionization chamber after the exposure operation starts. The on state indicates that the corresponding automatic exposure control ionization chamber is selected and used for automatic exposure control after the exposure operation starts, and the off state indicates that the corresponding automatic exposure control ionization chamber is not selected and is not used for automatic exposure control after the exposure operation starts. Figure 5 and Figure 6 As shown, rectangles of different filling colors can be used to distinguish between the open state and the closed state. For example, a white rectangle is used to represent the closed state (not selected), and a dark rectangle is used to represent the open state (selected). The reverse is also possible. The embodiment of the present application is not limited to this. Rectangles of different sizes can also be used to distinguish between the open state and the closed state. For example, a small rectangle is used to represent the closed state (not selected), and a large rectangle is used to represent the open state (selected). Figure 7 and Figure 8 As shown, letters of different colors can be used to distinguish the on state or the off state, for example, gray letters are used to represent the off state (not selected), black letters are used to represent the on state (selected), etc., and examples are not given one by one here.

[0081] In some embodiments, when the marks of multiple automatic exposure control ionization chambers are initially superimposed and displayed, they can be defaulted to the closed state, or one of them can be defaulted to the open state and the others to the closed state. The embodiments of the present application are not limited to this.

[0082] In some embodiments, the input device may receive an input operation (fifth input operation) for setting the switch state of the multiple automatic exposure control ionization chambers, the fifth input operation including triggering (by moving the cursor to click or touch) a mark of one of the marks of the Z automatic exposure control ionization chambers displayed in a superimposed manner, and after receiving the input operation, the control device selects the automatic exposure control ionization chamber in the turned-on state to control the exposure time according to the received input operation for setting the switch state of the multiple automatic exposure control ionization chambers. For example, after receiving the fifth input operation, the style of the mark of the triggered automatic exposure control ionization chamber changes, indicating that the switch state is switched. For example, when the mark of the automatic exposure control ionization chamber is a white rectangle, after the mark is triggered, the mark changes to a dark rectangle, indicating that the automatic exposure control ionization chamber at the position corresponding to the mark is selected, and is in the turned-on state after the exposure operation starts, for automatic exposure control.

[0083] In some embodiments, when only one automatic exposure control ionization chamber can be selected to be in the on state for a sub-medical image, when a fifth input operation is received to change the automatic exposure control ionization chamber corresponding to the mark of the triggered automatic exposure control ionization chamber to the on state (for example, from a white rectangle to a dark rectangle), and there is an automatic exposure control ionization chamber corresponding to the mark of an untriggered automatic exposure control ionization chamber in the on state (that is, there is still an untriggered dark rectangle), synchronously with the fifth input operation, the control device changes the automatic exposure control ionization chamber corresponding to the mark of the untriggered automatic exposure control ionization chamber to the off state, that is, the display device synchronously updates the display style of the mark of the untriggered automatic exposure control ionization chamber (for example, from a dark rectangle to a white rectangle).

[0084] In some embodiments, Figures 5 to 8 As shown, the switch states 20111 of multiple automatic exposure control ionization chambers corresponding to each sub-medical image can also be synchronously displayed in the parameter setting display window 201. The switch states of the multiple automatic exposure control ionization chambers corresponding to each sub-medical image displayed in the parameter setting display window are the same as the switch states of the multiple automatic exposure control ionization chambers superimposed and displayed at the corresponding sub-medical image position of the captured image.

[0085] In some embodiments, Figure 2 and Figure 3As shown, the graphical user interface also includes a distance information display window 71 for filling in or adjusting or displaying the distance from the center of the region of interest to the detector plane, wherein, when performing medical imaging on the object to be detected, the object to be detected stands on a splicing frame, which refers to a support frame placed in front of the detector, and a scale is provided on the splicing frame. By the operator reading the measurement value of the scale, the distance from the center of the region of interest to the splicing frame can be directly determined. Since the distance between the splicing frame and the detector plane is fixed, the distance from the center of the region of interest to the detector plane can be determined. The operator can fill in and display the measurement value of the scale read in the distance information display window 71. In addition, the distance information display window 71 can also include an adjustment button 72 for adjusting the size of the distance. The implementation of the adjustment button 72 can refer to the first increase mark and the first decrease mark, which will not be repeated here.

[0086] In some embodiments, the control device performs exposure according to the set exposure parameters of each sub-medical image, wherein, when exposing a sub-medical image among the first number of sub-medical images, the exposure parameters of the sub-medical image displayed in the parameter setting display window 201 are the exposure parameters used for the current exposure, and the exposure parameters of the sub-medical image are displayed differently from the exposure parameters of other sub-medical images. For example, Fig. 9 is another schematic diagram of a graphical user interface of an embodiment of the present application, such as Fig. 9 As shown, for the set exposure parameters (for example, when the setting completion mark or the trigger start exposure mark is triggered, it means that the exposure parameters can no longer be adjusted, that is, the set exposure parameters), the exposure parameters displayed in the parameter setting display window will be locked and can no longer be adjusted (for example, it can be displayed as a non-editable state). When the sub-medical image #1 is exposed, the exposure parameters of the sub-medical image #1 in the parameter list are highlighted, and the exposure parameters of other sub-medical images are not highlighted. In the parameter list, the exposure parameters of the row where the sub-medical image #1 is located are displayed as the exposure parameters used for the current exposure. After the exposure of the sub-medical image #1 is completed, the sub-medical image #2 is exposed. The exposure parameters of the sub-medical image #2 in the parameter list are highlighted, and the exposure parameters of other sub-medical images are not highlighted (the exposure parameters of the sub-medical image #1 that has completed the exposure can be displayed in gray), and so on, until the exposure of all sub-medical images is completed.

[0087] In some embodiments, optionally, when exposing one of the first number of sub-medical images, the exposure parameters currently used for the exposure of the sub-medical image may be displayed in the adjustment display window 45. For example, Fig. 9As shown, when the sub-medical image #1 is exposed, the exposure parameters (tube voltage 90KV, tube current 500mA) used for the exposure of the sub-medical image #1 displayed in the display window 45 are adjusted; after the exposure of the sub-medical image #1 is completed, the sub-medical image #2 is exposed, and the exposure parameters (tube voltage 85KV, tube current 500mA) used for the exposure of the sub-medical image #2 displayed in the display window 45 are adjusted, and so on, until the exposure of all the sub-medical images is completed.

[0088] The above input operations may also be input by voice, and the embodiments of the present application are not limited thereto.

[0089] The above embodiments are merely exemplary of the embodiments of the present application, but the present application is not limited thereto, and appropriate modifications may be made based on the above embodiments. For example, the above embodiments may be used alone, or one or more of the above embodiments may be combined.

[0090] The embodiments of the present application also provide a medical imaging method, and the contents that are the same as those in the embodiments of the aforementioned aspects are not repeated here. Fig.10 is a schematic diagram of a medical imaging method according to an embodiment of the present application, such as Fig.10 As shown, the method includes:

[0091] 1001, displaying a graphical user interface including a parameter setting display window, wherein the parameter setting display window simultaneously displays exposure parameters of each sub-medical image in a first number of sub-medical images, wherein the first number of sub-medical images are spliced ​​to form a medical image of a detected object, and the first number is greater than or equal to 2;

[0092] 1004 , performing exposure according to the exposure parameters of each of the sub-medical images, and splicing the first number of sub-medical images after exposure to generate the medical image.

[0093] In some embodiments, the method may further include:

[0094] 1003, receiving a second input operation of adjusting exposure parameters of a second number of sub-medical images in the first number of sub-medical images, where the second number is greater than or equal to 1 and less than or equal to the first number;

[0095] And in 1004, exposure is performed according to the exposure parameter of each medical sub-image adjusted by the second input operation.

[0096] In some embodiments, the method may further include:

[0097] 1002 : Receive a first input operation of selecting the second number of sub-medical images.

[0098] It is worth noting that the above Fig.10 The embodiments of the present application are only schematically described, but the present application is not limited thereto. For example, the execution order between the various operations can be appropriately adjusted. In addition, some other operations can be added or some of the operations can be reduced, such as reducing 1002, or reducing 1002 and 1003, etc. Alternatively, at least one of the following operations can be added: when the input device receives the third input operation that triggers the exposure parameter reset mark, the exposure parameters of the first number of sub-medical images displayed in the parameter setting display window are updated to the default values; or the exposure parameters of the second number of sub-medical images displayed in the parameter setting display window are updated to the default values; and when the input device receives the fourth input operation that triggers the focal spot adjustment mark, the focal spot size is switched, and the upper limit or lower limit of the exposure parameter is adjusted to the upper limit or lower limit corresponding to the adjusted focal spot, etc. Those skilled in the art can make appropriate modifications based on the above content, and are not limited to the above-mentioned appended claims. Fig.10 Records of.

[0099] The above embodiments are merely exemplary of the embodiments of the present application, but the present application is not limited thereto, and appropriate modifications may be made based on the above embodiments. For example, the above embodiments may be used alone, or one or more of the above embodiments may be combined.

[0100] An embodiment of the present application also provides a graphical user interface, which includes a parameter setting window, and the parameter setting window simultaneously displays the exposure parameters of each sub-medical image in a first number of sub-medical images, wherein the first number of sub-medical images are spliced ​​to form a medical image of the detected object, and the first number is greater than or equal to 2.

[0101] In some embodiments, the graphical user interface also includes an exposure parameter reset mark. When the exposure parameter reset mark is triggered, the exposure parameters of the first number of sub-medical images displayed in the parameter setting display window are updated to default values; or the exposure parameters of the second number of sub-medical images displayed in the parameter setting display window are updated to default values, and the second number is greater than or equal to 1 and less than or equal to the first number.

[0102] In some embodiments, the graphical user interface also includes a focus adjustment mark. When the focus adjustment mark is triggered, the upper limit value or the lower limit value of the exposure parameter is adjusted to the upper limit value or the lower limit value corresponding to the adjusted focus; and when there is an exposure parameter of the sub-medical image in the parameter setting display window that exceeds the adjusted upper limit value or is less than the adjusted lower limit value, the exposure parameter of the sub-medical image displayed in the parameter setting display window is updated to the adjusted upper limit value or the adjusted lower limit value.

[0103] In some embodiments, the graphical user interface also includes an area for displaying a captured image, and marks of switch states of multiple automatic exposure control ionization chambers corresponding to a second number of sub-medical images superimposed on the captured image, and by triggering the switch state marks, the states of each automatic exposure control ionization chamber corresponding to the second number of sub-medical images are set to on or off, and the second number is greater than or equal to 1 and less than or equal to the first number; and the states of each automatic exposure control ionization chamber corresponding to each sub-medical image are simultaneously displayed in the parameter setting display window.

[0104] In some embodiments, the graphical user interface further includes a distance information display window for filling in, adjusting or displaying the distance between the center of the region of interest and the detector plane.

[0105] The implementation of each window or mark above can refer to the above embodiments (such as Figures 2 to 9 Any one is shown), which will not be repeated here.

[0106] The medical imaging system, medical imaging method and graphical user interface provided by the present application simultaneously display the exposure parameters of each sub-medical image in all sub-medical images by designing a parameter setting display window. Therefore, there is no need to switch windows or interfaces. In the window of the same interface, the operator can intuitively view the exposure parameters of all sub-medical images, thereby simplifying the operation, and the exposure parameters of each sub-medical image can be intuitively compared and displayed.

[0107] In addition, the control device can generate recommended exposure parameter values ​​according to the algorithm and perform exposure processing according to the recommended exposure parameter values. Therefore, the operator is not required to adjust the exposure parameters, which improves efficiency. Exposure according to the recommended parameters can also ensure the quality of the exposure image.

[0108] In addition, executing the second input operation can support adjusting the exposure parameters of multiple sub-medical images at the same time, thereby eliminating the need to adjust the exposure parameters of each sub-medical image one by one, further simplifying the operation and steps of adjusting the parameters and saving the parameter adjustment time.

[0109] In addition, when one of the sub-medical images is selected for exposure parameter adjustment, the absolute value of the exposure parameter can be adjusted directly, and when multiple sub-medical images are selected for exposure parameter adjustment, the relative values ​​of multiple sub-medical images can be increased or decreased at the same time. As a result, there is no need to adjust the exposure parameters of each sub-medical image one by one, which further simplifies the operation and steps of adjusting the parameters and saves the time of parameter adjustment.

[0110] In addition, during the exposure process or after the exposure is completed, the exposure parameters actually used can be displayed in the parameter setting display window for the operator's reference.

[0111] In addition, by setting multiple groups of parameter adjustment marks, the exposure parameters can be roughly adjusted and finely adjusted respectively, making the adjustment of the exposure parameters more flexible.

[0112] In addition, the adjustment of the focal spot is taken into consideration while adjusting the exposure parameters, making the adjustment of the exposure parameters more flexible.

[0113] In addition, by designing an exposure parameter reset mark, the operator can quickly restore the initial settings when the exposure parameters are adjusted incorrectly.

[0114] In addition, the marks of the switch status of multiple automatic exposure control ionization chambers are superimposed and displayed on the captured image, and the status of each automatic exposure control ionization chamber corresponding to the second number of sub-medical images is set to on or off by triggering the switch status mark, thereby making the selection of the automatic exposure control ionization chamber more intuitive and convenient.

[0115] The above devices and methods of the present application can be implemented by hardware, or by hardware combined with software. The present application relates to such a computer-readable program, which, when executed by a logic component, enables the logic component to implement the above-mentioned devices or components, or enables the logic component to implement the various methods or steps described above. The present application also relates to a storage medium for storing the above program, such as a hard disk, a magnetic disk, an optical disk, a DVD, a flash memory, etc.

[0116] The method / device described in conjunction with the embodiments of the present application may be directly embodied as hardware, a software module executed by a processor, or a combination of the two. For example, one or more of the functional block diagrams shown in the figure and / or one or more combinations of the functional block diagrams may correspond to various software modules of the computer program flow or to various hardware modules. These software modules may correspond to the various steps shown in the figure, respectively.

[0117] The software module may be located in a RAM memory, a flash memory, a ROM memory, an EPROM memory, an EEPROM memory, a register, a hard disk, a removable disk, a CD-ROM, or any other form of storage medium known in the art. A storage medium may be coupled to a processor so that the processor can read information from the storage medium and write information to the storage medium; or the storage medium may be an integral part of the processor.
