Description

Technical Field

[0001] This application relates to the field of medical system technology, and in particular to a method, device, storage medium and DR system for displaying the rotation angle of an X-ray tube. Background Technology

[0002] Digital radiography (DR) systems are advanced medical systems that combine computer digital image processing technology with X-ray radiation technology. DR systems are widely used due to their low radiation dose, high image quality, and high disease detection rate and diagnostic accuracy.

[0003] The rotation angle of the X-ray tube around the horizontal axis in a DR system is called the RHA (Relative Harmonic Adjustment), which is a crucial reference point for clinical technicians during setup. Currently, the RHA angle in most DR systems is defined as 0° vertically downwards from the opening of the X-ray tube constrictor. In certain testing scenarios, such as when the subject is standing, the RHA angle feedback may not match the user's desired X-ray incident angle. To achieve the desired angle, calculations must be performed based on the current RHA angle to determine the relationship between the RHA angle and the X-ray incident angle. This increases the calculation time and the probability of errors, leading to low gantry setup efficiency.

[0004] Therefore, the rack placement efficiency of DR systems is a problem in related technologies. Summary of the Invention

[0005] Therefore, it is necessary to provide a method, device, DR system, computer-readable storage medium, and computer program product for displaying the rotation angle of an X-ray tube, which can improve the rack positioning efficiency of a DR system, in response to the above-mentioned technical problems.

[0006] Firstly, this application provides a method for displaying the rotation angle of an X-ray tube. The method includes:

[0013] When the positioning angle feedback input is triggered, the placement direction is determined to be vertical.

[0014] When the supine angle feedback input is triggered, the placement direction is determined to be horizontal.

[0015] In one embodiment, the method is applied to a DR system; when the flat panel detector is located outside the cassette, there are marker points on the surface of the flat panel detector; detecting the placement orientation of the flat panel detector includes:

[0019] The placement orientation of the flat panel detector is determined based on the rotation angle of the flat panel detector relative to the zero point of the DR system.

[0020] In one embodiment, when the flat panel detector is located within the cassette, the placement orientation of the detection flat panel detector includes:

[0021] Determine the current angle acquisition system used;

[0022] If the angle acquisition system currently used is a supine angle acquisition system, then the placement direction is determined to be horizontal.

[0023] If the angle acquisition system currently used is a standing angle acquisition system, then the placement direction is determined to be vertical.

[0024] In one embodiment, displaying the current value of the X-ray tube rotation angle based on the zero-degree baseline of the X-ray tube rotation angle includes:

[0025] The offset angle between the incident direction of the X-ray tube on the flat panel detector and the zero-degree reference line is determined and used as the current value of the rotation angle of the X-ray tube;

[0026] Displays the current value of the rotation angle of the X-ray tube.

[0027] In one embodiment, the placement direction matches the examination position of the subject; displaying the current value of the X-ray tube rotation angle includes:

[0028] Determine the target quadrant region corresponding to the detected body position;

[0029] If the incident direction falls within the target quadrant region, the current value of the X-ray tube rotation angle is displayed as a positive value;

[0030] Otherwise, the current value of the rotation angle of the X-ray tube is displayed as a negative value.

[0031] Secondly, this application also provides a display device for the rotation angle of an X-ray tube. The device includes:

[0032] The detection module is used to detect the placement orientation of the flat panel detector;

[0033] The determining module is used to take a line perpendicular to the placement direction and passing through the X-ray tube as the zero-degree reference line for the rotation angle of the X-ray tube; the rotation angle of the X-ray tube is the rotation angle of the X-ray tube about the horizontal axis.

[0034] The display module is used to display the current value of the X-ray tube rotation angle based on the zero-degree baseline of the X-ray tube rotation angle.

[0035] Thirdly, this application also provides a DR system. The DR system includes a memory and a processor, the memory storing a computer program, and the processor executing the computer program to perform the following steps:

[0036] Detect the placement orientation of the flat panel detector;

[0037] A line perpendicular to the placement direction and passing through the X-ray tube is used as the zero-degree reference line for the rotation angle of the X-ray tube; the rotation angle of the X-ray tube is the rotation angle of the X-ray tube around the horizontal axis.

[0038] The current value of the X-ray tube rotation angle is displayed based on the zero-degree baseline of the X-ray tube rotation angle.

[0039] Fourthly, this application also provides a computer-readable storage medium. The computer-readable storage medium stores a computer program thereon, which, when executed by a processor, performs the following steps:

[0040] Detect the placement orientation of the flat panel detector;

[0041] A line perpendicular to the placement direction and passing through the X-ray tube is used as the zero-degree reference line for the rotation angle of the X-ray tube; the rotation angle of the X-ray tube is the rotation angle of the X-ray tube around the horizontal axis.

[0042] The current value of the X-ray tube rotation angle is displayed based on the zero-degree baseline of the X-ray tube rotation angle.

[0043] Fifthly, this application also provides a computer program product. The computer program product includes a computer program that, when executed by a processor, performs the following steps:

[0044] Detect the placement orientation of the flat panel detector;

[0045] A line perpendicular to the placement direction and passing through the X-ray tube is used as the zero-degree reference line for the rotation angle of the X-ray tube; the rotation angle of the X-ray tube is the rotation angle of the X-ray tube around the horizontal axis.

[0046] The current value of the X-ray tube rotation angle is displayed based on the zero-degree baseline of the X-ray tube rotation angle.

[0047] The above-mentioned X-ray tube rotation angle display method, device, DR system, storage medium, and computer program product detect the placement direction of the flat panel detector; take a line perpendicular to the placement direction and passing through the X-ray tube as the zero-degree reference line for the X-ray tube rotation angle; the X-ray tube rotation angle is the rotation angle of the X-ray tube around the horizontal axis; and display the current value of the X-ray tube rotation angle based on the zero-degree reference line for the X-ray tube rotation angle. Thus, since the X-ray tube rotation angle is determined based on the offset between the X-ray tube's incident direction on the flat panel detector and the zero-degree baseline, and the zero-degree baseline is perpendicular to the placement direction of the flat panel detector, the calculation logic of the X-ray tube rotation angle is consistent with the calculation logic of the X-ray incident angle. This ensures that the definition of the X-ray tube rotation angle meets the actual placement requirements of the flat panel detector, and that the calculation logic of the X-ray tube rotation angle is adaptively adjusted according to the actual placement of the flat panel detector. This ensures that the feedback of the X-ray tube rotation angle is consistent with the clinically required X-ray incident angle. Consequently, during the gantry placement process based on the desired incident angle, the user does not need to first calculate based on the current X-ray tube rotation angle to determine the conversion relationship between the current X-ray tube rotation angle and the desired incident angle. This reduces the angle calculation process and the probability of angle calculation errors, avoids complex calculations, and allows direct gantry placement based on the displayed current value of the X-ray tube rotation angle, improving gantry placement efficiency.

[0056] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0057] It should be noted that the terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this disclosure are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this disclosure described herein can be implemented in orders other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0058] In one embodiment, such as Figure 1 As shown, a method for displaying the rotation angle of an X-ray tube is provided. This embodiment illustrates the application of this method to a DR system. In this embodiment, the method includes the following steps:

[0059] Step S110: Detect the placement orientation of the flat panel detector.

[0060] In practice, the DR system can detect the placement direction of the flat panel detector, and the placement direction matches the placement state of the flat panel detector, which includes horizontal placement and vertical placement.

[0061] Step S120: The line perpendicular to the placement direction and passing through the X-ray tube is used as the zero-degree reference line for the rotation angle of the X-ray tube.

[0062] The rotation angle of the X-ray tube is the rotation angle of the X-ray tube about the horizontal axis (RHA).

[0063] In practice, the DR system can use a line perpendicular to the placement direction and passing through the X-ray tube as the zero-degree reference line for the rotation angle of the X-ray tube. That is, the DR system can use the straight line passing through the X-ray tube when the X-ray tube is perpendicular to the flat panel detector as the zero-degree reference line for the rotation angle of the X-ray tube.

[0064] Step S130: Display the current value of the X-ray tube rotation angle based on the zero-degree baseline of the X-ray tube rotation angle.

[0065] The DR system includes a display device, which is used to display the angle display interface.

[0066] In practice, when the incident direction of the X-ray tube to the flat panel detector coincides with the zero-degree reference line of the X-ray tube's rotation angle, the value of the X-ray tube's rotation angle is 0 degrees. In this way, the DR system can determine the current value of the X-ray tube's rotation angle according to the X-ray tube rotation angle calculation logic that matches the zero-degree reference line after the user controls the movement of the X-ray tube, and display the current value of the X-ray tube's rotation angle on the angle display interface of the display device.

[0067] In the above-mentioned method for displaying the rotation angle of the X-ray tube, the placement direction of the flat panel detector is detected; a line perpendicular to the placement direction and passing through the X-ray tube is used as the zero-degree reference line for the rotation angle of the X-ray tube; the rotation angle of the X-ray tube is the rotation angle of the X-ray tube around the horizontal axis; and the current value of the rotation angle of the X-ray tube is displayed according to the zero-degree reference line for the rotation angle of the X-ray tube. Thus, since the X-ray tube rotation angle is determined based on the offset between the X-ray tube's incident direction on the flat panel detector and the zero-degree baseline, and the zero-degree baseline is perpendicular to the placement direction of the flat panel detector, the calculation logic of the X-ray tube rotation angle is consistent with the calculation logic of the X-ray incident angle. This ensures that the definition of the X-ray tube rotation angle meets the actual placement requirements of the flat panel detector, and that the calculation logic of the X-ray tube rotation angle is adaptively adjusted according to the actual placement of the flat panel detector. This ensures that the feedback of the X-ray tube rotation angle is consistent with the clinically required X-ray incident angle. Consequently, during the gantry placement process based on the desired incident angle, the user does not need to first calculate based on the current X-ray tube rotation angle to determine the conversion relationship between the current X-ray tube rotation angle and the desired incident angle. This reduces the angle calculation process and the probability of angle calculation errors, avoids complex calculations, and allows direct gantry placement based on the displayed current value of the X-ray tube rotation angle, improving gantry placement efficiency.

[0068] In one embodiment, detecting the placement orientation of the flat panel detector includes: determining the placement orientation in response to a triggering operation of an angle feedback inlet in an angle display interface.

[0069] The angle feedback input includes an icon used to represent the direction of the zero-degree baseline.

[0070] The angle display interface includes an angle feedback entry point, which in practical applications can be an angle feedback button.

[0071] In specific implementation, the angle feedback entry in the angle display interface includes an icon representing the direction of the zero-degree baseline. The zero-degree baseline matches the placement direction of the flat panel detector. The user can click the angle feedback entry in the angle display interface that matches the current placement direction of the flat panel detector. In this way, during the process of detecting the placement direction of the flat panel detector, the DR system can respond to the trigger operation of the angle feedback entry in the angle display interface to determine the placement direction of the flat panel detector.

[0072] The technical solution of this embodiment determines the placement direction by responding to a trigger operation of the angle feedback input in the angle display interface. The angle feedback input includes an icon representing the direction of the zero-degree baseline, allowing users to easily understand the calculation rules for different X-ray tube rotation angles. Thus, the user can trigger an angle feedback input matching the current placement direction of the flat panel detector, enabling the DR system to accurately determine the placement direction in response to the trigger operation of the angle feedback input in the angle display interface.

[0073] In one embodiment, the angle feedback input includes a standing angle feedback input and a lying angle feedback input; in response to a triggering operation of the angle feedback input in the angle display interface, the placement direction is determined, including: when the standing angle feedback input is triggered, the placement direction is determined to be vertical; when the lying angle feedback input is triggered, the placement direction is determined to be horizontal.

[0074] In specific implementation, the angle feedback inputs include standing angle feedback inputs and lying angle feedback inputs. When the DR system responds to the triggering operation of the angle feedback inputs on the angle display interface and determines the placement direction, when the standing angle feedback input is triggered, the placement direction is determined to be vertical, indicating that the current imaging position is standing. At this time, the horizontal straight line passing through the X-ray tube when the tube is perpendicular to the flat panel detector is the zero-degree reference line. It should be noted that when the placement direction is vertical, when the incident direction of the X-ray tube to the flat panel detector coincides with the zero-degree reference line of the X-ray tube rotation angle (i.e., when the X-ray tube is horizontal), the X-ray tube can be facing directly towards the chest frame (Bucky-Wall-Stand, BWS) assembly or facing away from the BWS assembly; in this case, the X-ray tube rotation angle value is 0 degrees. Simultaneously, when the placement direction is vertical, the X-ray tube rotation angle calculation logic that matches the zero-degree reference line of the X-ray tube rotation angle can be named the standing calculation logic.

[0075] When the supine angle feedback input is triggered, the placement direction is determined to be horizontal, indicating that the current imaging position is supine. At this time, the vertical line passing through the X-ray tube when it is perpendicular to the flat panel detector is the zero-degree reference line. It should be noted that when the placement direction is horizontal, if the incident direction of the X-ray tube to the flat panel detector coincides with the zero-degree reference line of the X-ray tube rotation angle, that is, when the X-ray tube is vertical, the value of the X-ray tube rotation angle is 0 degrees. Furthermore, when the placement direction is horizontal, the X-ray tube rotation angle calculation logic that matches the zero-degree reference line of the X-ray tube rotation angle can be named the supine position calculation logic.

[0076] Users can switch the X-ray tube rotation angle calculation logic by clicking different angle feedback inputs according to the current placement orientation of the flat panel detector, so as to meet the user's need to switch the X-ray tube rotation angle calculation logic themselves.

[0077] For the ease of understanding of those skilled in the art, Figure 2 A schematic diagram of a standing angle feedback inlet and a lying angle feedback inlet is provided.

[0078] In this embodiment, the angle feedback input includes a standing angle feedback input and a lying angle feedback input. When the standing angle feedback input is triggered, the placement direction is determined to be vertical; when the lying angle feedback input is triggered, the placement direction is determined to be horizontal. Thus, by using standing and lying angle feedback inputs corresponding to different placement directions, users can switch the X-ray tube rotation angle calculation logic themselves and select the angle feedback input that matches the current placement direction of the flat panel detector. This satisfies the user's need to switch the calculation logic independently, thereby accurately determining the placement direction of the flat panel detector in response to triggering operations of either the standing or lying angle feedback input.

[0079] In one embodiment, when the flat panel detector is located outside the cassette, there are marker points on the surface of the flat panel detector; such as Figure 3 As shown, step S110, detecting the placement orientation of the flat panel detector, includes:

[0080] Step S310: Obtain the image of the flat panel to be identified by the image acquisition device taking a picture of the flat panel detector aligned with the frame.

[0081] When the flat panel detector is located outside the chip box, the flat panel detector is a free flat panel.

[0082] In practice, when the flat panel detector is a free flat panel, that is, when the flat panel detector is located outside the chip box, the image acquisition device can capture video footage of the flat panel detector aligned with the frame while the frame is aligned with the flat panel detector to obtain the image of the flat panel to be identified.

[0083] Step S320: Identify the marker points in the flat panel image to be identified, and determine the three-dimensional position coordinates of the flat panel detector relative to the zero point of the DR system.

[0084] In practice, the DR system can determine the three-dimensional position coordinates of the flat panel detector relative to the zero point of the DR system by identifying the marker points in the image of the flat panel to be identified.

[0085] Step S330: Determine the rotation angle of the flat panel detector relative to the zero point of the DR system based on the three-dimensional position coordinates.

[0086] In practice, the DR system can determine the rotation angle of the flat panel detector relative to the zero point of the DR system based on the three-dimensional position coordinates.

[0087] Step S340: Determine the placement direction of the flat panel detector based on the rotation angle of the flat panel detector relative to the zero point of the DR system.

[0088] In practice, the DR system can determine whether the placement direction of the flat panel detector is horizontal or vertical based on the rotation angle of the flat panel detector relative to the zero point of the DR system.

[0089] In this embodiment, when the flat panel detector is located outside the chip holder, there are marker points on the surface of the flat panel detector. Thus, when the flat panel detector is a free flat panel, an image of the flat panel to be identified is obtained by acquiring an image of the flat panel detector aligned with the frame through an image acquisition device. The marker points in the image of the flat panel to be identified are identified to determine the three-dimensional position coordinates of the flat panel detector relative to the zero point of the DR system. The rotation angle of the flat panel detector relative to the zero point of the DR system is determined based on the three-dimensional position coordinates. Based on the rotation angle of the flat panel detector relative to the zero point of the DR system, the placement direction of the flat panel detector can be automatically and accurately determined, improving the efficiency of detecting the placement direction of the flat panel detector.

[0090] In one embodiment, when the flat panel detector is located inside the chip box, detecting the placement direction of the flat panel detector includes: determining the currently used angle acquisition system; if the currently used angle acquisition system is a horizontal angle acquisition system, then determining the placement direction is horizontal; if the currently used angle acquisition system is a vertical angle acquisition system, then determining the placement direction is vertical.

[0091] In its implementation, the DR system includes an angle acquisition system. When the flat panel detector is located inside the cassette, the angle acquisition system automatically determines the rotation angle of the flat panel detector relative to the zero point of the DR system, thereby determining the placement direction of the flat panel detector and employing X-ray tube rotation angle calculation logic that matches the placement direction of the flat panel detector. Specifically, when the placement direction is vertical, the X-ray tube rotation angle calculation logic is an upright calculation logic, and the angle acquisition system using the upright calculation logic can be named an upright angle acquisition system; when the placement direction is horizontal, the X-ray tube rotation angle calculation logic is a supine calculation logic, and the angle acquisition system using the supine calculation logic can be named a supine angle acquisition system.

[0092] In this way, the DR system can determine the current angle acquisition system used; if the current angle acquisition system used is a supine angle acquisition system, the placement direction is determined to be horizontal; if the current angle acquisition system used is an upright angle acquisition system, the placement direction is determined to be vertical.

[0093] In this embodiment, when the flat panel detector is located inside the cassette, the angle acquisition system can automatically determine the rotation angle of the flat panel detector relative to the zero point of the DR system to determine the placement direction of the flat panel detector, and use the X-ray tube rotation angle calculation logic that matches the placement direction. Thus, by determining the currently used angle acquisition system, if the currently used angle acquisition system is a horizontal angle acquisition system, the placement direction is determined to be horizontal; if the currently used angle acquisition system is a vertical angle acquisition system, the placement direction is determined to be vertical, which can efficiently and accurately determine the placement direction of the flat panel detector.

[0094] In one embodiment, displaying the current value of the X-ray tube rotation angle based on the zero-degree reference line of the X-ray tube rotation angle includes: determining the offset angle between the incident direction of the X-ray tube to the flat panel detector and the zero-degree reference line, as the current value of the X-ray tube rotation angle; and displaying the current value of the X-ray tube rotation angle.

[0095] In practice, after the user controls the movement of the X-ray tube, the DR system can determine the offset angle between the incident direction of the X-ray tube to the flat panel detector and the zero-degree baseline, and display the current value of the X-ray tube rotation angle in the angle display interface.

[0096] The placement direction matches the examination position of the subject; the current value of the X-ray tube rotation angle is displayed, including: determining the target quadrant region corresponding to the examination position; if the incident direction falls into the target quadrant region, the current value of the X-ray tube rotation angle is displayed as a positive value; otherwise, the current value of the X-ray tube rotation angle is displayed as a negative value.

[0097] The examination position of the subject includes at least one of standing and supine positions. When the subject is standing, the placement direction is vertical; when the subject is supine, the placement direction is horizontal.

[0098] Among them, the target quadrant region corresponding to the test position is the quadrant region that matches the target part of the test subject.

[0099] The target part can be the head. In a rectangular coordinate system with the X-ray tube as the center and the zero-degree baseline as one coordinate axis, the quadrant where the target part is located is the quadrant that matches the target part of the object being inspected.

[0100] Among them, the location of the target part can be represented by a preset label.

[0101] For example, to facilitate understanding by those skilled in the art, Figure 4A schematic diagram is provided showing the current value of the X-ray tube rotation angle (RHA) when the flat panel detector is placed vertically and the positioning calculation logic is used.

[0102] like Figure 4 As shown in the left half of the dashed line, when the X-ray tube is directly facing the Bucky-Wall-Stand (BWS) assembly and the RHA is 0 degrees, the straight line indicated by the arrow represents the zero-degree baseline that matches the positioning calculation logic; the crosshairs represent the position of the head. At this time, a Cartesian coordinate system is established with the X-ray tube as the center, the arrow direction at RHA of 0 degrees as the positive x-axis, and vertical downwards as the positive y-axis. The quadrant region where the head is located is the first and second quadrant regions in the aforementioned Cartesian coordinate system. If the incident direction falls within the first or second quadrant region, the current value of the X-ray tube rotation angle is displayed as a positive value; otherwise, if the incident direction does not fall within the target quadrant region, i.e., if the incident direction falls within the third or fourth quadrant region, the current value of the X-ray tube rotation angle is displayed as a negative value.

[0103] like Figure 4 As shown in the right half of the dashed line, with the X-ray tube facing away from the Bucky-Wall-Stand (BWS) assembly, when the RHA is 0 degrees, the straight line indicated by the arrow represents the zero-degree baseline that matches the positioning calculation logic; the crosshairs represent the position of the head. At this time, a Cartesian coordinate system is established with the X-ray tube as the center, the arrow direction at RHA 0 degrees as the positive x-axis, and the vertically upward direction as the positive y-axis. The quadrant region where the head is located is the first and second quadrant regions in the aforementioned Cartesian coordinate system. If the incident direction falls within the first or second quadrant region, the current value of the X-ray tube rotation angle is displayed as a positive value; otherwise, if the incident direction does not fall within the target quadrant region, i.e., if the incident direction falls within the third or fourth quadrant region, the current value of the X-ray tube rotation angle is displayed as a negative value.

[0104] For the ease of understanding of those skilled in the art, Figure 5 A schematic diagram is provided showing the current value of the X-ray tube rotation angle (RHA) when the flat panel detector is placed horizontally and a horizontal calculation logic is used. For example... Figure 5As shown, when RHA is 0 degrees, the straight line indicated by the arrow represents the zero-degree baseline that matches the calculation logic for the supine position; the crosshairs represent the position of the head. At this time, a rectangular coordinate system is established with the X-ray tube as the center, the arrow direction when RHA is 0 degrees as the positive y-axis, and the horizontal rightward direction as the positive x-axis. The quadrant region where the head is located is the first and fourth quadrant regions in the aforementioned rectangular coordinate system. If the incident direction falls within the first or fourth quadrant region, the current value of the X-ray tube rotation angle is displayed as a positive value; otherwise, if the incident direction does not fall within the target quadrant region, i.e., if the incident direction falls within the second or third quadrant region, the current value of the X-ray tube rotation angle is displayed as a negative value.

[0105] Similarly, when using the supine position calculation logic, when the position of the head is... Figure 5 When the head position is reversed, the quadrant region where the head is located corresponds to the second and third quadrant regions in the Cartesian coordinate system of the supine position described above. If the incident direction falls within the second or third quadrant region, the current value of the X-ray tube rotation angle is displayed as a positive value; otherwise, if the incident direction does not fall within the target quadrant region, i.e., if the incident direction falls within the first or fourth quadrant region, the current value of the X-ray tube rotation angle is displayed as a negative value.

[0106] The technical solution of this embodiment determines the offset angle between the incident direction of the X-ray tube on the flat panel detector and the zero-degree reference line as the current value of the X-ray tube rotation angle; displays the current value of the X-ray tube rotation angle; wherein, the placement direction matches the detection position of the object being inspected, and the target quadrant region corresponding to the detection position is determined; if the incident direction falls into the target quadrant region, the current value of the X-ray tube rotation angle is displayed as a positive value; otherwise, the current value of the X-ray tube rotation angle is displayed as a negative value. Thus, since the zero-degree reference line is perpendicular to the placement direction of the flat panel detector, the feedback of the current value of the X-ray tube rotation angle is consistent with the incident angle of the X-ray. Therefore, during the gantry positioning process according to the desired incident angle, the user does not need to first calculate based on the current X-ray tube rotation angle to determine the relationship between the current X-ray tube rotation angle and the desired incident angle, reducing the angle calculation process and the probability of angle calculation errors, avoiding complex calculations, and allowing direct gantry positioning based on the displayed current value of the X-ray tube rotation angle, thus improving gantry positioning efficiency.

[0107] In another embodiment, such as Figure 6 As shown, a method for displaying the rotation angle of an X-ray tube is provided. Taking the application of this method in a DR system as an example, the method includes the following steps:

[0108] Step S610: Detect the placement orientation of the flat panel detector.

[0109] Step S620: The line perpendicular to the placement direction and passing through the X-ray tube is used as the zero-degree reference line for the rotation angle of the X-ray tube.

[0110] Step S630: Determine the offset angle between the incident direction of the X-ray tube to the flat panel detector and the zero-degree reference line, as the current value of the X-ray tube rotation angle.

[0111] Step S640: Determine the target quadrant region corresponding to the detection position.

[0112] In step S650, if the incident direction falls within the target quadrant region, the current value of the X-ray tube rotation angle is displayed as a positive value; otherwise, the current value of the X-ray tube rotation angle is displayed as a negative value.

[0113] It should be noted that the specific limitations of the above steps can be found in the specific limitations of a method for displaying the rotation angle of an X-ray tube described above.

[0114] Since the X-ray tube rotation angle is determined based on the offset between the X-ray tube's incident direction on the flat panel detector and the zero-degree baseline, the aforementioned X-ray tube rotation angle display method ensures that the specified zero-degree baseline is perpendicular to the placement direction of the flat panel detector. This ensures that the calculation logic for the X-ray tube rotation angle is consistent with the calculation logic for the X-ray incident angle, achieving a definition of the X-ray tube rotation angle that meets the actual placement requirements of the flat panel detector. It also enables adaptive adjustment of the X-ray tube rotation angle calculation logic based on the actual placement of the flat panel detector, ensuring that the feedback of the X-ray tube rotation angle matches the clinically required X-ray incident angle. Furthermore, during the gantry placement process based on the desired incident angle, the user does not need to first calculate based on the current X-ray tube rotation angle to determine the conversion relationship between the current X-ray tube rotation angle and the desired incident angle. This reduces the angle calculation process and the probability of errors, avoiding complex calculations. The gantry can be placed directly based on the displayed current value of the X-ray tube rotation angle, improving gantry placement efficiency.

[0115] It should be understood that although the steps in the flowcharts of the embodiments described above are shown sequentially according to the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless explicitly stated herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders. Moreover, at least some steps in the flowcharts of the embodiments described above may include multiple steps or multiple stages. These steps or stages are not necessarily completed at the same time, but can be executed at different times. The execution order of these steps or stages is not necessarily sequential, but can be performed alternately or in turn with other steps or at least some of the steps or stages of other steps.
