Description

Technical Field

[0001] This application relates to the field of radiotherapy technology, and in particular to a display method, system, device and storage medium for adjusting patient positioning reference lines. Background Technology

[0002] Currently, when using a ring accelerator to perform radiotherapy on patients, the patient can be positioned inside the device using a treatment bed. Furthermore, before radiotherapy, image guidance (such as CBCT guidance) is required to verify that the center of the patient's target area in the positioning position is aligned with the treatment center of the device. If they are not aligned, the treatment bed needs to be moved to adjust the positioning position, or the beam direction of the device needs to be adjusted to eliminate the positioning error.

[0003] However, the equipment is reset after radiotherapy. Therefore, this method of eliminating positioning errors only applies to the current fractionated radiotherapy session, resulting in positioning errors existing in each subsequent radiotherapy session for the same patient. This necessitates image-guided positioning before each radiotherapy session, which can easily increase the radiation dose received by the patient and reduce treatment efficiency. Summary of the Invention

[0043] The technical solution provided in this application brings at least the following beneficial effects:

[0044] In this application, positioning deviations can be identified and displayed on the interface in multiple coordinate axes, allowing the therapist to understand these deviations. Furthermore, if the positioning deviation meets the adjustment criteria, an alarm message can be used to instruct the therapist to perform position adjustment operations on the patient's positioning reference line in multiple coordinate axes.

[0045] Because the patient's positioning reference line has been adjusted, during the next radiotherapy session, the patient can be positioned according to the corrected pre-positioning location based on the adjusted reference line, and then accurately moved to the target position. This minimizes positioning errors and achieves precision treatment. Furthermore, subsequent radiotherapy sessions can be conducted without image guidance, simplifying the workflow, reducing the frequency of image guidance use and the radiation dose received by the patient during image guidance, while simultaneously improving positioning accuracy and treatment efficiency.

[0046] Furthermore, the interface can display alarm information and highlight the deviation value of the coordinate axis to be adjusted, which makes it easier for the treating physician to accurately and clearly understand the deviation and adjust the position of the positioning reference line in the direction of the coordinate axis to be adjusted.

[0047] Furthermore, this application can accurately instruct the treating physician on the timing of adjusting the patient's positioning reference line by displaying prompts on the interface indicating whether the positioning deviation is stabilizing. This helps to accurately adjust the patient's positioning reference line, thereby reducing the frequency of image guidance and the radiation dose received by the patient in a timely and effective manner, and improving treatment efficiency.

[0048] Furthermore, this application can quickly and accurately reset the patient positioning reference line in cases where the reference line is blurred or lost, or where the patient's body shape changes suddenly, demonstrating high flexibility. Attached Figure Description

[0057] The term "and / or" as used in this application includes using either one of two methods or using both methods simultaneously.

[0058] The terms “first,” “second,” and “third,” etc., used in the specification and drawings of this application are used to distinguish different objects, not to describe a specific order of objects, nor to indicate or imply relative importance or to implicitly specify the number of technical features indicated.

[0059] In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0060] The following describes the implementation scenarios involved in the display method, system, device, and storage medium for adjusting patient positioning reference lines provided in the embodiments of this application.

[0061] Currently, when using a ring accelerator to perform radiotherapy on patients, the patient can be positioned inside the device using a treatment bed. Furthermore, before radiotherapy, image guidance is required to verify that the center of the patient's target area in the positioning position is aligned with the treatment center of the device. If they are not aligned, the treatment bed needs to be moved to adjust the positioning position, or the beam direction of the device needs to be adjusted to eliminate the positioning error.

[0062] However, the equipment is reset after radiotherapy. Therefore, this method of eliminating positioning errors only applies to the current radiotherapy session, resulting in positioning errors existing in every subsequent radiotherapy session for the same patient. This necessitates image-guided positioning before each session, potentially increasing the radiation dose received by the patient and reducing treatment efficiency.

[0063] In the display method for adjusting the patient positioning reference line in the first aspect of this application:

[0064] In order to improve positioning accuracy and treatment efficiency while reducing the frequency of image-guided use and the radiation dose received by patients, this application provides a display method for adjusting the patient positioning reference line.

[0065] The method for displaying the patient positioning reference line adjustment includes: determining and displaying positioning deviations in multiple coordinate axes on the interface based on the patient's pre-treatment position and target position. The pre-treatment position is determined based on the patient's pre-positioning position, which is obtained by positioning the patient using the positioning reference line. The target position is the patient's position after image guidance or during beam exit therapy. If the positioning deviation meets the adjustment conditions, an alarm message is generated and displayed on the interface to instruct the treating physician to perform position adjustment operations on the positioning reference line in multiple coordinate axes.

[0066] Based on this, this application can determine and display the positioning deviation in multiple coordinate axes on the interface based on the patient's pre-treatment position and target position, so that the treating physician can understand the positioning deviation. Furthermore, when the positioning deviation meets the adjustment conditions, an alarm message can instruct the treating physician to perform position adjustment operations on the patient's positioning reference line in multiple coordinate axes. Because the patient's positioning reference line has been adjusted, during the patient's next radiotherapy, the patient can be positioned to the corrected pre-position based on the adjusted positioning reference line, and further accurately moved to the target position, thus eliminating positioning errors as much as possible and achieving precise treatment. Moreover, subsequent radiotherapy procedures can be performed without image guidance, simplifying the workflow. Therefore, this application can improve positioning accuracy and treatment efficiency while reducing the frequency of image guidance and the radiation dose received by the patient.

[0067] like Figure 1 The diagram shown is a flowchart illustrating a method for adjusting a patient positioning reference line according to an embodiment of this application. The method includes steps S101-S102.

[0068] S101. Based on the patient's pre-treatment position and target position, determine and display the positioning deviation in multiple coordinate axis directions on the interface.

[0069] The pre-treatment position is determined based on the patient's pre-positioning. The pre-positioning is obtained by positioning the patient using a positioning reference line. The target position is the patient's position after image guidance is completed or during the outgoing beam treatment.

[0070] Optionally, the patient positioning reference line refers to the positioning reference line set by the treating physician on the patient's body surface (such as the surface of the head or body), or on a positioning device fixed to the patient (such as a head pin or positioning mask), or on a phantom prepared corresponding to the patient. This application does not limit this.

[0071] Specifically, before radiotherapy, a positioning laser and a patient positioning reference line can be set. Based on this, the patient can be placed on the treatment bed and pre-positioned according to the laser beam emitted by the positioning laser and the positioning reference line. When the laser beam emitted by the positioning laser and the patient's positioning reference line are aligned, the patient's pre-positioned position can be determined. This pre-positioned position is located outside the circular accelerator, which is the external laser lamp positioning position, also known as the virtual isocenter.

[0072] Furthermore, after determining the patient's pre-positioning location, the treatment bed can be moved into the circular accelerator according to a predefined direction and distance. Once the treatment bed has completed its movement, the patient is confirmed to be in the pre-treatment position. That is, the relative positional difference between the pre-positioning location and the pre-treatment position is fixed. The predefined direction and distance can be set based on this fixed relative positional difference. Moreover, the pre-treatment position, located inside the circular accelerator, can also be considered the starting position for image guidance.

[0073] Furthermore, after determining the patient's pre-treatment position, the ring accelerator can be controlled to begin image guidance, and the treatment bed can be gradually moved according to the image guidance to bring the patient's target area closer to the treatment center. Once the patient's target area and the treatment center coincide, the ring accelerator can be controlled to end image guidance. In this case, the patient's position can be determined as the target position, and the ring accelerator can be controlled to begin beam exit therapy.

[0074] In this way, the patient's pre-positioning position, pre-treatment position, and target position can be determined. Specifically, the pre-positioning position, pre-treatment position, and target position can be represented by three-dimensional coordinates, that is, by specific coordinate positions on the horizontal axis (X-axis), vertical axis (Y-axis), and vertical axis (Z-axis).

[0075] For example, the patient's prepositioning position can be represented by the three-dimensional coordinates of the treatment bed when the patient is in the prepositioning position, the patient's pretreatment position can be represented by the three-dimensional coordinates of the treatment bed when the patient is in the pretreatment position, and the patient's target position can be represented by the three-dimensional coordinates of the treatment bed when the patient is in the target position.

[0076] Furthermore, the positioning deviation in multiple coordinate axes can be determined based on the patient's pre-treatment position and target position. For example, the positioning deviation in multiple coordinate axes (X1, Y1, Z1) can be determined based on the three-dimensional coordinates of the pre-treatment position and the three-dimensional coordinates of the target position.

[0077] Furthermore, in this case, to facilitate the physician's understanding of the positioning deviation, the positioning deviation can be displayed on the interface in multiple coordinate axes.

[0078] S102. If the positioning deviation meets the adjustment conditions, generate and display alarm information on the interface to instruct the physician to perform position adjustment operations on the positioning reference line in multiple coordinate axis directions.

[0079] The adjustment conditions can be used to indicate the unreasonable range of positioning deviation. For example, adjustment conditions may include positioning deviation being outside a preset range. When positioning deviation is outside the preset range, it can be determined that the positioning deviation is large and within an unreasonable range. In this case, the difference between the patient's target area and the treatment center is large, and the patient's position needs to be adjusted. When positioning deviation is within the preset range, it can be determined that the positioning deviation is small and within a reasonable range. In this case, the difference between the patient's target area and the treatment center is small, and the patient's position does not need to be adjusted.

[0080] Optionally, the preset range can be flexibly set according to the precision requirements of the beam delivery therapy. For example, when the target area is located in the patient's head and neck, the preset range can be within 3 mm. Or, when the target area is located in the patient's body, the preset range can be within 5 mm.

[0081] Based on this, if the positioning deviation is within the preset range, it indicates that the difference between the pre-treatment position and the target position is small. That is, when the patient is in the pre-treatment position, the difference between the patient's target area and the treatment center is small, meeting the accuracy requirements of beam delivery therapy, and no adjustment of the patient's position is necessary. In this case, it can be determined that the positioning deviation does not meet the adjustment conditions. Alternatively, an alarm can be generated and displayed on the interface to indicate that the positioning deviation is within the preset range.

[0082] If the positioning deviation is outside the preset range, it indicates a significant difference between the pre-treatment position and the target position. Specifically, when the patient is in the pre-treatment position, the difference between the patient's target area and the treatment center is large, failing to meet the accuracy requirements of beam delivery therapy. In this case, it can be determined that the patient's position needs adjustment, generating and displaying alarm information on the interface to instruct the therapist to perform position adjustment operations on the positioning reference line in multiple coordinate axes. Alternatively, the alarm information can also be used to indicate that the positioning deviation does not conform to the preset range.

[0083] It should be noted that, considering the fixed relative positional difference between the pre-positioning position and the pre-treatment position, if the patient's pre-positioning position is corrected based on this positioning deviation, and the patient is placed in the corrected pre-positioning position, the treatment bed can be moved into the ring accelerator according to a predefined direction and distance to allow the patient to reach the target position.

[0084] Based on this, alarm information can instruct the treating physician to perform position adjustment operations on the patient's positioning reference line in multiple coordinate axis directions. Then, the positioning laser and the adjusted patient positioning reference line can be used for pre-positioning, thereby achieving the effect of correcting the patient's pre-positioning position.

[0085] Furthermore, by adjusting the patient positioning reference line, the patient can be pre-positioned to the corrected pre-positioning position based on the adjusted reference line during the next radiotherapy session, and then accurately positioned to the target position, minimizing positioning errors and achieving precision treatment. Moreover, subsequent radiotherapy procedures can be conducted without image guidance, simplifying the workflow. Therefore, this application can improve positioning accuracy and treatment efficiency while reducing the frequency of image guidance and the radiation dose received by the patient.

[0086] In some embodiments, when determining and displaying the positioning deviation in multiple coordinate axis directions in S101 based on the patient's pre-treatment position and target position, the embodiments of this application provide the following optional implementation methods, including: S101a-S101c.

[0087] S101a. Based on the pre-treatment position and the target position, obtain the first positioning deviation of the pre-treatment position and the target position in multiple coordinate axis directions, determine and display the first positioning deviation in the interface.

[0088] For example, the three-dimensional coordinates of the pre-treatment position and the three-dimensional coordinates of the target position can be subtracted to determine the first positioning deviation between the pre-treatment position and the target position in multiple coordinate axis directions, that is, the positional deviation of the pre-treatment position and the target position on the horizontal axis (i.e., X-axis), vertical axis (i.e., Y-axis), and vertical axis (i.e., Z-axis), respectively. Furthermore, the first positioning deviation can be displayed on the interface.

[0089] S101b: Obtain the corresponding target placement position through the target position; based on the pre-placement position and the target placement position, obtain the second placement deviation of the pre-placement position and the target placement position in multiple coordinate axis directions; determine and display the second placement deviation in the interface.

[0090] Based on the description in S101 above, and considering that the relative positional difference between the pre-positioning position and the pre-treatment position is fixed, the three-dimensional coordinates of the target positioning position, i.e., the modified pre-positioning position, can be determined based on the three-dimensional coordinates of the target position and the fixed relative positional difference.

[0091] Furthermore, the three-dimensional coordinates of the pre-positioning position and the target position can be subtracted to determine the second positioning deviation between the pre-positioning position and the target position along multiple coordinate axes. This deviation represents the positional deviation between the pre-positioning position and the target position on the horizontal axis (X-axis), vertical axis (Y-axis), and vertical axis (Z-axis), respectively. This second positioning deviation can then be displayed on the interface.

[0092] S101c: Obtain the position of the target reference line corresponding to the target placement position through the target position; based on the position of the placement reference line and the position of the target reference line, obtain the third placement deviation of the position of the placement reference line and the position of the target reference line in multiple coordinate axis directions; determine and display the third placement deviation in the interface.

[0093] For example, the patient's target position can be represented by the three-dimensional coordinates of the target area center when the patient is in the target position. The patient's target positioning position can be represented by the three-dimensional coordinates of the target area center when the patient is in the target positioning position. It should be understood that the method of obtaining the target positioning position from the target position is described in S101b above, and will not be repeated here.

[0094] Furthermore, the position of the target reference line can be determined based on the three-dimensional coordinates of the target positioning position, i.e., the three-dimensional coordinates of the target area center when the patient is in the target positioning position, combined with the patient's three-dimensional image. For example, based on the patient's three-dimensional image, the positional difference between the patient's target area center and the patient's body surface can be determined, and combined with the three-dimensional coordinates of the target area center, the three-dimensional coordinates of the target reference line can be determined.

[0095] Furthermore, the three-dimensional coordinates of the target reference line and the three-dimensional coordinates of the placement reference line can be subtracted to obtain the third placement deviation between the position of the placement reference line and the position of the target reference line in multiple coordinate axis directions, and the second placement deviation can be displayed in the interface.

[0096] In some embodiments, in the above-described S102, that is, when the positioning deviation meets the adjustment conditions, an alarm message is generated and displayed in the interface to instruct the physician to perform position adjustment operations on the positioning reference line in multiple coordinate axis directions, the embodiments of this application provide the following optional implementation methods, including: S102a-S102c.

[0097] S102a. If the first positioning deviation exceeds the first preset range, generate and display alarm information on the interface to instruct the physician to perform position adjustment operations on the positioning reference line in multiple coordinate axis directions.

[0098] S102b: If the second positioning deviation exceeds the second preset range, generate and display alarm information on the interface to instruct the physician to perform position adjustment operations on the positioning reference line in multiple coordinate axis directions.

[0099] S102c. If the third positioning deviation exceeds the third preset range, generate and display alarm information on the interface to instruct the physician to perform position adjustment operations on the positioning reference line in multiple coordinate axis directions.

[0100] It should be understood that the setting methods for the first, second, and third preset ranges can be understood with reference to the setting methods for the preset ranges in S102 above. Furthermore, the comparison processing methods for the first positioning deviation and the first preset range, the second positioning deviation and the second preset range, and the third positioning deviation and the third preset range can be understood with reference to the comparison processing methods for the positioning deviation and the preset ranges in S102 above. These will not be elaborated upon here.

[0101] In some embodiments, when generating and displaying alarm information in the interface to instruct the physician to perform position adjustment operations on the positioning reference line in multiple coordinate axis directions in S102, this application embodiment provides an optional implementation method, including: S201-S202.

[0102] S201. Determine the text information included in the alarm message, and determine the coordinate axis to be adjusted corresponding to the alarm message.

[0103] The alarm information includes textual information that can be used to indicate the coordinate axis to be adjusted, as well as the deviation value in the direction of the coordinate axis to be adjusted.

[0104] Specifically, the deviation values ​​on the horizontal, vertical, and axial axes of the positioning deviation can be determined separately to see if they exceed preset ranges. If the deviation value in any coordinate axis direction exceeds the preset range, then that coordinate axis is determined as the coordinate axis to be adjusted, and the deviation value in that coordinate axis direction is determined as the deviation value in the direction of the coordinate axis to be adjusted. Furthermore, based on the coordinate axis to be adjusted and the deviation value in the direction of the coordinate axis to be adjusted, the text information included in the alarm message can be determined.

[0105] As an example, a predefined text template for the alarm message when the positioning deviation meets the adjustment conditions can be provided. For instance, the text template for the alarm message when the positioning deviation meets the adjustment conditions could be: "Please adjust the positioning reference line in the direction of the 'axis to be adjusted' according to the deviation value in the direction of the axis to be adjusted." In this case, if the deviation value of 6mm in the horizontal axis direction is determined to be outside the preset range, then the horizontal axis is determined to be the axis to be adjusted, and the deviation value of 6mm in the horizontal axis direction is determined to be the deviation value in the direction of the axis to be adjusted.

[0106] Furthermore, based on the text template, the horizontal axis, and the deviation value of 6mm in the horizontal axis direction, the text information included in the alarm message can be determined as: Please adjust the positioning reference line in the horizontal axis direction according to the deviation value of 6mm in the horizontal axis direction.

[0107] S202. Display text information on the interface and highlight the deviation value of the coordinate axis to be adjusted to instruct the therapist to adjust the position of the positioning reference line in the direction of the coordinate axis to be adjusted.

[0108] To help physicians accurately and clearly understand the deviation, text information can be displayed on the interface, and the deviation value of the coordinate axis to be adjusted can be highlighted to instruct physicians to adjust the position of the positioning reference line in the direction of the coordinate axis to be adjusted.

[0109] For example, the text information corresponding to the deviation value of the coordinate axis to be adjusted can be bolded, or the text information corresponding to the deviation value of the coordinate axis to be adjusted can be set to a different color (such as red) than other text information, so as to highlight the deviation value of the coordinate axis to be adjusted.

[0110] In some embodiments, when generating and displaying alarm information in the interface to instruct the physician to perform position adjustment operations on the positioning reference line in multiple coordinate axis directions in S102, this application embodiment provides another optional implementation, including: S301.

[0111] S301. Determine and display the adjustment reference value in the direction of the coordinate axis to be adjusted in the interface, so as to instruct the therapist to adjust the position of the positioning reference line in the direction of the coordinate axis to be adjusted according to the adjustment reference value.

[0112] As an example, the deviation value in the direction of the coordinate axis to be adjusted can be determined as the adjustment reference value in that direction. Furthermore, the adjustment reference value in the direction of the coordinate axis to be adjusted can be displayed on the interface to instruct the therapist to adjust the position of the positioning reference line in that direction based on the adjustment reference value.

[0113] In another example, an adjustment reference value can be determined in the direction of the coordinate axis to be adjusted based on a preset range and the deviation value in that direction. Furthermore, the adjustment reference value in the direction of the coordinate axis to be adjusted can be displayed on the interface to instruct the therapist to adjust the position of the positioning reference line in that direction according to the adjustment reference value.

[0114] For example, the difference between the deviation value in the direction of the coordinate axis to be adjusted and the right end value of the preset range can be determined as the adjustment reference value in the direction of the coordinate axis to be adjusted.

[0115] For example, the difference between the deviation value in the direction of the coordinate axis to be adjusted and the median value of the preset range can be determined as the adjustment reference value in the direction of the coordinate axis to be adjusted.

[0116] In some embodiments, the display method for adjusting the patient positioning reference line provided in this application may further include: S401.

[0117] S401. In response to the therapist performing a position adjustment operation on the positioning reference line in multiple coordinate axis directions, the position of the adjusted positioning reference line is updated synchronously and displayed in the interface.

[0118] For example, after the therapist adjusts the positioning reference line in multiple coordinate axes, the patient can be positioned on the treatment bed. Further, pre-positioning can be performed based on the positioning laser and the adjusted positioning reference line, and the adjusted pre-positioning position can be determined. Then, based on the initial and adjusted pre-positioning positions, the position of the adjusted positioning reference line can be updated synchronously and displayed on the interface.

[0119] For example, after a therapist adjusts the position of the positioning reference line along multiple coordinate axes, they can input the adjustment information. This information indicates the coordinate axis direction in which the adjustment was performed, as well as the adjustment value along that axis. Furthermore, based on the input adjustment information and the patient's initial positioning reference line position, the adjusted position can be updated synchronously and displayed on the interface.

[0120] In some embodiments, when the positioning deviation in multiple coordinate axis directions is determined and displayed on the interface based on the patient's pre-treatment position and target position in S101 above, this application embodiment provides an optional implementation method, including: S1011.

[0121] S1011. Based on the pre-treatment position and the target position, the positioning deviation is obtained. Based on the statistical characteristics of the positioning deviation and the historical positioning deviation, the positioning deviation in multiple coordinate axis directions and the prompt information on whether the positioning deviation tends to be stable are displayed in the interface.

[0122] As an example, after obtaining the positioning deviation based on the pre-treatment position and the target position, historical positioning deviations determined during the patient's past radiotherapy can be read, and the statistical characteristics between the currently determined positioning deviation and the historical positioning deviation can be determined. Furthermore, based on the statistical characteristics of the positioning deviation and the historical positioning deviation, it can be determined whether the positioning deviation tends to stabilize.

[0123] For example, the average or variance between the currently determined setup deviation and the historical setup deviation can be used. If the difference between the average of the currently determined setup deviation and the historical setup deviation and the historical setup deviation is less than or equal to a difference threshold, then the setup deviation can be determined to be stable. If the difference between the average of the currently determined setup deviation and the historical setup deviation and the historical setup deviation is greater than a difference threshold, then the setup deviation can be determined to be unstable.

[0124] Furthermore, the interface can display the placement deviation in multiple coordinate axes and prompts indicating whether the placement deviation is stabilizing.

[0125] It should be noted that when the positioning deviation has not stabilized, it may indicate that the patient's body shape is still changing significantly, or that the positioning techniques used by the treating physicians in that fraction are different, leading to a large deviation. In this case, if the patient's positioning reference line is adjusted, the adjusted reference line will still change with the patient's body shape. During subsequent radiotherapy for this patient, accurate positioning based on the adjusted reference line will still be difficult.

[0126] When positioning deviations stabilize, it indicates that the patient's body shape changes are minimal or nonexistent, or that the physician's positioning technique is standardized. In this case, adjusting the patient's positioning reference line will not cause it to change with the patient's body shape. Therefore, during subsequent radiotherapy, positioning can be accurately performed based on the adjusted reference line, reducing the frequency of image guidance and the patient's radiation dose, thus improving treatment efficiency.

[0127] Based on this, this application can accurately instruct the treating physician on when to adjust the patient's positioning reference line by displaying prompts on the interface indicating whether the positioning deviation is stabilizing. This helps to accurately adjust the patient's positioning reference line, thereby timely and effectively reducing the frequency of image-guided treatment and the radiation dose received by the patient, thus improving treatment efficiency. It avoids adjusting the patient's positioning reference line in cases where a large deviation occurs occasionally, which could lead to inaccurate positioning before subsequent treatment sessions.

[0128] It should be understood that the method for obtaining the positioning deviation based on the pre-treatment position and the target position can be referred to the above description of S101, and will not be repeated here.

[0129] In some embodiments, when the patient's positioning reference line is blurred or lost, or when the patient's body characteristics change significantly (e.g., sudden weight loss), pre-positioning can be performed based on a reference position, a blurred position, or a previous positioning position to accurately reset the patient's positioning reference line. The reference position represents a position corresponding to prior knowledge, such as a pre-positioning position set based on the treating physician's experience. The blurred position represents the periphery of the patient's target area, i.e., a pre-positioning position set based on the location of the patient's target area. The previous positioning position is the pre-positioning position used during the previous radiotherapy treatment of the patient.

[0130] Furthermore, the pre-treatment position and target position can be determined based on the pre-positioning position obtained from the pre-positioning based on the reference position, the ambiguous position, or the previous positioning position. Then, based on the pre-treatment position and target position, the positioning deviation in multiple coordinate axis directions can be determined and displayed on the interface. This allows the treating physician to accurately set the patient's positioning reference line based on the positioning deviation, thereby reducing the frequency of image guidance in subsequent radiotherapy and the radiation dose received by the patient, and improving treatment efficiency.

[0131] Based on this, this application can quickly and accurately reset the patient positioning reference line in cases where the reference line is blurred or lost, or where the patient's body shape changes suddenly, thus providing high flexibility.

[0133] In some embodiments, based on the example of the display method for adjusting the patient positioning reference line described in the first aspect above, the device performing the display method for adjusting the patient positioning reference line in the first aspect can be divided into functional modules.
