[0057] In this embodiment, a method for displaying radiotherapy information is provided. Figure 2 is a flow chart of a method for displaying radiotherapy information according to an embodiment of the present application. Figure 2 As shown, the process includes the following steps:

[0058] Step S201, obtaining radiotherapy plan information corresponding to fractionated treatment, where the radiotherapy plan information includes a planned radiotherapy dose.

[0059] In this embodiment, the radiotherapy plan information includes time nodes corresponding to the fractionated treatment and the planned radiotherapy dose corresponding to each time node.

[0060] Step S202, obtaining medical images corresponding to the fractionated treatment.

[0061] Step S203, determining the actual radiotherapy dose of each treatment fraction according to the medical image.

[0062] In this embodiment, the medical image can be CT, CBCT, MR, PET, PET-CT, PET-MR acquired by any imaging device, or a combination of CT, CBCT, MR, PET, PET-CT, PET-MR, but is not limited to the above-mentioned medical images. The imaging information during the patient treatment process belongs to the medical image of this embodiment.

[0063] It should be noted that CBCT is the abbreviation of Cone beam CT.

[0064] Step S204, determining the radiation dose deviation of each treatment fraction according to the planned radiation dose and the actual radiation dose.

[0065] In this embodiment, the radiotherapy dose deviation of each fractionated treatment is determined according to the planned radiotherapy dose and the actual radiotherapy dose of each fractionated treatment. For example, the radiation treatment plan information formulated for the patient includes multiple fractionated treatment information. It is assumed that the radiation treatment plan information of the patient includes three fractionated treatment information, and the times of the three fractionated treatments are 2020.1.1, 2020.1.15 and 2020.1.30, respectively. The planned radiotherapy dose and the actual radiotherapy dose corresponding to 2020.1.1 are 100 and 90, respectively. Then, the radiotherapy dose deviation corresponding to the treatment time node 2020.1.1 is determined according to the planned radiotherapy dose of 100 and the actual radiotherapy dose of 90. According to this method, the radiotherapy dose deviations corresponding to the other two fractionated treatments are obtained respectively, and the radiotherapy dose deviation trend graph can be determined according to the dose deviations of each fractionated treatment.

[0066] Step S205, generating a radiotherapy dose deviation trend graph according to the radiotherapy dose deviations corresponding to the multiple fractionated treatments, and displaying the radiotherapy dose deviation trend graph in the interactive interface.

[0067] For example, the radiation dose deviation trend diagram is as follows Figure 3 As shown, the percentage in the left column is the deviation between the actual radiotherapy dose field and the planned radiotherapy dose field, but it is not limited to the above comparison method. The deviation display in the radiotherapy deviation trend chart can be adjusted according to the actual situation.

[0068] It should be noted that this example does not specifically limit the form of expression of radiotherapy dose deviation in the interactive interface. For example, the radiotherapy dose deviation can be described by the ratio of the actual radiotherapy dose to the planned radiotherapy dose, or by the absolute value of the difference between the actual radiotherapy dose and the planned radiotherapy dose.

[0069] Through the above steps, medical images are obtained, and the actual radiotherapy dose of each fractionated treatment is determined based on the medical images, and radiation plan information is obtained. The radiotherapy dose deviation of each fractionated treatment is determined based on the planned radiotherapy dose corresponding to each fractionated treatment in the radiation plan information and the actual radiotherapy dose corresponding to each fractionated treatment, and a radiotherapy dose deviation trend graph is generated based on the radiotherapy dose deviation, and the radiotherapy dose deviation trend graph is displayed in the interactive interface. Therefore, the doctor can adjust the subsequent radiation therapy plan in time according to the radiotherapy dose deviation trend graph, which solves the problem of not being able to display multiple fractionated treatment results on one interface and realizes viewing of medical images and radiation therapy plan information in the same system.

[0070] It should be noted that the steps shown in the above process or the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although the logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in a different order from that here. For example, step S201 and step S202 can be interchanged.

[0071] In some embodiments, step S204, determining the radiotherapy dose deviation of each treatment fraction according to the planned radiotherapy dose and the actual radiotherapy dose, includes:

[0072] Obtain the gamma pass rate of the planned radiotherapy dose compared with the actual radiotherapy dose;

[0073] According to the gamma passing rate, the radiation dose deviation of each treatment fraction is determined.

[0074] In this embodiment, a larger gamma pass rate represents a smaller radiotherapy dose deviation, and a smaller gamma pass rate represents a larger radiotherapy dose deviation.

[0075] Through the above method, the actual radiotherapy dose and the planned radiotherapy dose are subjected to a three-dimensional spatial volume gamma analysis, so that the radiotherapy deviation between the actual radiotherapy dose and the planned radiotherapy dose can be accurately determined. Furthermore, the doctor can adjust the radiotherapy plan in time according to the radiotherapy dose deviation.

[0076] In some of the embodiments, the interactive interface further includes a first preset area, and the radiotherapy information display method further includes:

[0077] Receiving a first trigger instruction for an interactive interface at a first preset area;

[0078] In response to the first trigger instruction, the medical image and the radiation therapy plan information are displayed in the interactive interface.

[0079] In this embodiment, the first trigger instruction may be a touch operation, a mouse click operation, or an instruction sent remotely. This implementation does not specifically limit the triggering method corresponding to the first trigger instruction.

[0080] The first preset area may be the name of the treatment batch corresponding to the fractionated treatment, or may be the time node corresponding to the fractionated treatment in the radiotherapy dose deviation trend graph. This embodiment does not specifically limit the position of the first preset area.

[0081] It should be noted that the medical image in this embodiment refers to the actually collected medical image.

[0082] For example, Figure 4 As shown, Figure 4 The left column in the middle is the acquired medical image, and the right column is the radiotherapy plan information. In addition, the left column also shows the fusion of the medical image and the planned medical image. The fusion is used to show the deviation between the actual radiotherapy dose distribution and the planned radiotherapy dose distribution. The doctor can directly determine the deviation between the current actual radiotherapy dose and the planned radiotherapy dose based on the fusion. In addition, through Figure 3 The interface can be switched to the planned radiotherapy dose distribution interface, the actual radiotherapy dose distribution interface or the dose deviation trend graph by touch.

[0083] In the above manner, doctors can view medical images and radiotherapy plan information on the same interface, so that they can adjust subsequent radiotherapy plan information in a timely manner based on the medical images.

[0084] In some of the embodiments, the interactive interface further includes a second preset area and a third preset area, and the radiotherapy information display method further includes:

[0085] Receiving a second trigger instruction for the interactive interface at a second preset area;

[0086] In response to the second trigger instruction, displaying the medical image in the interactive interface; and / or

[0087] Receiving a third trigger instruction for the interactive interface at a third preset area;

[0088] In response to the third trigger instruction, the radiation therapy plan information is displayed in the interactive interface.

[0089] In this embodiment, the second trigger instruction and the third trigger instruction may be touch operations, mouse click operations, or remotely sent instructions. This implementation does not specifically limit the triggering method corresponding to the first trigger instruction.

[0090] The second preset area can be where the name of each medical image is displayed, or it can be the time node corresponding to the fractionated treatment in the radiotherapy dose deviation trend chart. The third preset area can be where the name of each radiotherapy plan is displayed, or it can be the time node corresponding to the fractionated treatment in the radiotherapy dose deviation trend chart. This implementation does not make specific limitations on the second preset area and the third preset area.

[0091] Through the above method, it is achieved to display medical images and radiotherapy plan information in the same interactive interface, so that doctors can adjust subsequent radiotherapy plan information according to the medical images in a timely manner.

[0092] In some of the embodiments, the interactive interface further includes a preview area, and the radiotherapy information display method further includes:

[0093] Receiving a second trigger instruction for the interactive interface at a second preset area;

[0094] In response to the second trigger instruction, displaying the medical image in the preview area; and / or

[0095] Receiving a third trigger instruction for the interactive interface at a third preset area;

[0096] In response to the third trigger instruction, the radiation therapy plan information is displayed in the preview area.

[0097] In this embodiment, the second trigger instruction and the third trigger instruction may be touch operations, mouse click operations, or remotely sent instructions. This implementation does not specifically limit the triggering method corresponding to the first trigger instruction.

[0098] The second preset area can be where the name of each medical image is displayed, or it can be the time node corresponding to the fractionated treatment in the radiotherapy dose deviation trend chart. The third preset area can be where the name of each radiotherapy plan is displayed, or it can be the time node corresponding to the fractionated treatment in the radiotherapy dose deviation trend chart. This implementation does not make specific limitations on the second preset area and the third preset area.

[0099] The preview area is as follows Figure 5 As shown, Figure 5 The left column 51 in the figure represents a radiotherapy dose deviation trend graph, the right column 52 represents a preview area, PlanCT, FBCT1, FBCT2, FBCT3, FBCT4 and FBCT5 represent medical image names, and Plan0, Plan1, Plan2 and Plan3 represent radiotherapy plan names.

[0100] Through the above method, it is achieved to view the medical image and the radiotherapy plan information in the same preview area, so that the doctor can adjust the subsequent radiotherapy plan information according to the medical image in a timely manner.

[0101] In addition, during the treatment process, there will be movement of anatomical tissue and displacement errors between fractionated treatments, such as breathing and peristaltic movement, daily positioning errors, target area shrinkage, etc., which will cause changes in the radiotherapy dose distribution. Therefore, it is necessary to take field photographs before the start of treatment and during the treatment process. The guidance of medical images can reduce radiotherapy errors caused by changes in tumor position due to positioning or organ movement. This embodiment determines the deviation between the medical image and the planned medical image in the following way to reduce radiotherapy errors caused by changes in tumor position due to positioning or organ movement.

[0102] In some embodiments, the radiotherapy plan information further includes a planned medical image corresponding to each treatment fraction, and the radiotherapy information display method further includes:

[0103] determining a registration deviation between the planning medical image and the medical image;

[0104] If the registration deviation is greater than the first preset threshold, a prompt message is displayed on the interactive interface.

[0105] In this embodiment, the current fractionated medical image and the planned medical image are registered using a deformable registration algorithm in medical image registration. The planned medical image can be CT, CBCT, MR, PET, PET-CT, PET-MR acquired by any imaging device, or a combination of CT, CBCT, MR, PET, PET-CT, and PET-MR, but is not limited to the above-mentioned medical images. The image information during the patient's treatment process belongs to the medical image of this embodiment.

[0106] For example, the current fractionated medical image is the acquired CBCT image, and the planned medical image is the CBCT image actually acquired last time. The CBCT image actually acquired in the current fraction is registered with the CBCT image actually acquired last time using the deformation registration algorithm in medical image registration, and the anatomical structure and planned radiotherapy dose in the CBCT image actually acquired last time are mapped to the CBCT image actually acquired in the current fraction according to the deformation registration matrix, such as Figure 6 As shown, Figure 6 It is a schematic diagram of an image registration interface according to an embodiment of the present application.

[0107] Through the above method, the registration of the medical image and the planned medical image is achieved, and when the registration deviation is greater than the first preset threshold, a prompt message pops up, thereby prompting the doctor in time to adjust the subsequent planned radiotherapy dose.

[0108] In some of the embodiments, the interactive interface further includes a status display area corresponding to the fractionated treatment, and the status display area is used to display indication information of the radiation dose.

[0109] In this embodiment, the indication information of the radiation dose can be determined according to the deviation between the actual radiotherapy dose and the planned radiotherapy dose, but is not limited to the above method. For example, the indication information of the radiation dose can be determined according to the registration deviation between the above medical image and the planned medical image, or the indication information of the radiation dose can be determined according to two factors: the radiotherapy dose deviation and the image registration deviation. In addition, the status display area can be marked as green, red, checked and / or other indication information. The user can judge the treatment result based on this mark. For example, when the status display area is marked as a green checked state, it means that the current fractionated treatment result requirement is passed. If the status display area is marked as a red cross state, it means that the current fractionated treatment result requirement is not passed. If the status display area is marked as a yellow exclamation mark state, it means that the current fractionated treatment result status is abnormal. In addition, the user can click on the status display area to view the specific content.

[0110] For example, the radiation dose indication information is determined based on the deviation between the actual radiotherapy dose and the planned radiotherapy dose. When the deviation between the actual radiotherapy dose and the planned radiotherapy dose is greater than the set threshold, the display area is marked in red, but the display of the radiation dose indication information is not limited to the above method. For example, the radiation dose indication information can be displayed in the form of a pop-up prompt box. This embodiment does not specifically limit how to display the radiation dose indication information.

[0111] Through the above method, the display of the radiation dose indication information is realized, which makes it easier for doctors to understand the results of the fractionated treatment and improves the efficiency of doctors in adjusting the subsequent treatment plan information.

[0112] In some embodiments, determining the radiation therapy dose deviation for each treatment fraction comprises:

[0113] If the radiotherapy dose deviation is greater than the second preset threshold, a prompt message will pop up on the interactive interface.

[0114] By using the above method, when the deviation between the actual radiotherapy dose and the planned radiotherapy dose is greater than the second preset threshold, a prompt message pops up, thereby prompting the doctor in time to adjust the subsequent planned radiotherapy dose.

[0115] In this embodiment, a method for displaying radiotherapy information is also provided, the method comprising:

[0116] In response to the trigger instruction, a radiotherapy dose deviation trend graph is displayed in the interactive interface, and the interactive interface includes each treatment time node area corresponding to each of the multiple radiotherapy dose deviations, a medical image name area corresponding to each treatment time node, and a radiotherapy plan name area corresponding to each treatment time node, wherein the radiotherapy dose deviation trend graph is determined based on the planned radiotherapy dose and the actual radiotherapy dose, and the actual radiotherapy dose is determined based on the medical image.

[0117] In this embodiment, the medical images include scanned CT images and positioning images of the previous treatment before the current treatment. The positioning images of the previous treatment before the current treatment include CBCT images obtained from an image-guided positioning device, but are not limited to the above-mentioned medical images. The imaging information during the patient's treatment process belongs to the medical images of this embodiment.

[0118] It should be noted that CBCT is the abbreviation of Cone beam CT.

[0119] For example, the radiation dose deviation trend diagram is as follows Figure 3 As shown, the percentage in the left column is the ratio of the actual radiotherapy dose to the planned radiotherapy dose, PlanCT, PlanCT1, PlanCT2, PlanCT3, PlanCT4 and PlanCT5 represent the names of medical images, and Plan0, Plan1, Plan2 and Plan3 represent the names of radiotherapy plans.

[0120] It should be noted that this example does not specifically limit the form of expression of radiotherapy dose deviation in the interactive interface. For example, the radiotherapy dose deviation can be described by the ratio of the actual radiotherapy dose to the planned radiotherapy dose, or by the absolute value of the difference between the actual radiotherapy dose and the planned radiotherapy dose.

[0121] Through the above method, it is possible to view medical images and radiotherapy plan information in the same system, and display the radiotherapy dose deviation trend chart in the interactive interface. Therefore, doctors can adjust subsequent radiotherapy plans in time according to the radiotherapy dose deviation trend chart, solving the problem of not being able to display multiple fractionated treatment results on one interface.

[0122] In this embodiment, a method for adjusting a radiotherapy plan is also provided, and a subsequent radiotherapy plan is adjusted according to the above-mentioned method for displaying radiotherapy information.

[0123] It can be understood that the present embodiment displays the radiotherapy dose deviation trend chart, medical images and radiotherapy plan information in the interactive interface in the above manner. Therefore, the doctor can adjust the subsequent radiotherapy plan in time according to the radiotherapy dose deviation trend chart, thus solving the problem of not being able to display the results of multiple fractionated treatments on one interface.

[0124] In some of the embodiments, the interactive interface further includes the name of the treatment batch corresponding to each fractionated treatment, and the method for displaying radiotherapy information further includes:

[0125] Receiving a fourth touch operation on the interactive interface at the first preset area;

[0126] In response to the fourth touch operation, actual radiotherapy dose information and radiotherapy plan information are displayed in the interactive interface.

[0127] For example, Figure 7 As shown, Figure 7 The upper part 71 of the middle left column is the planned medical image. Figure 7 The lower half 72 of the middle left column is the planned radiotherapy dose, and the right column 73 is the actual radiotherapy dose information.

[0128] In the above manner, doctors can view the actual radiotherapy dose and radiotherapy plan information on the same interface, so that they can adjust subsequent radiotherapy plan information in a timely manner based on medical images.

[0129] Figure 8 is a flow chart of another method for displaying radiotherapy information according to an embodiment of the present application. Figure 8 As shown, the radiotherapy information display method includes the following steps:

[0130] Step S801, obtaining radiotherapy plan information, where the radiotherapy plan information includes fractionated treatment and the planned radiotherapy dose corresponding to each fractionated treatment.

[0131] Step S802, obtaining medical images collected during each treatment session.

[0132] Step S803, determining the actual radiotherapy dose of each treatment fraction according to the medical image.

[0133] Step S804, determining the radiation dose deviation of each treatment fraction according to the planned radiation dose and the actual radiation dose.

[0134] Step S805, generating a radiotherapy dose deviation trend graph according to the radiotherapy dose deviation of each fractionated treatment, and displaying the dose deviation trend graph in an interactive interface, wherein the interactive interface also includes a medical image name corresponding to each medical image and a radiotherapy plan name corresponding to each fractionated treatment.

[0135] Step S806: receiving a first touch operation on the interactive interface at the display position of the medical image name.

[0136] Step S807: displaying a medical image in the interactive interface in response to the first touch operation.

[0137] Step S808, receiving a second touch operation on the interactive interface at the display position of the radiation therapy plan name.

[0138] Step S809: in response to the second touch operation, displaying the radiation therapy plan information in the interactive interface.

[0139] Through the above method, it is possible to view medical images and radiotherapy plan information in the same system, and display the radiotherapy dose deviation trend chart in the interactive interface. Therefore, doctors can adjust subsequent radiotherapy plans in time according to the radiotherapy dose deviation trend chart, solving the problem of not being able to display multiple fractionated treatment results on one interface.

[0140] It should be noted that the steps shown in the above process or the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although the logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in a different order from that here.

[0141] Fig. 9 is a schematic diagram of the radiotherapy process according to an embodiment of the present application, such as Fig. 9 As shown, the planned medical image is determined in the CT Sim system, and the contour information of the tumor target area and the organ at risk drawn by the doctor in the planned medical image is used as the anatomical structure, and the radiotherapy plan information is formulated, and the radiotherapy plan information includes the fractionated treatment and the planned radiotherapy dose corresponding to each fractionated treatment; the current fractionated medical image is acquired, and the current fractionated medical image and the planned medical image are registered using the deformation registration algorithm in the medical image registration, and the anatomical structure and the planned radiotherapy dose in the planned medical image are mapped to the medical image actually acquired in the current fraction according to the deformation registration matrix, and when the registration deviation is greater than the set threshold, a prompt message is sent to the user;

[0142] In addition, this embodiment calculates the actual radiotherapy dose based on the actually collected medical images, determines the gamma pass rate of the planned radiotherapy dose and the gamma pass rate of the actual radiotherapy dose, and determines the radiotherapy dose deviation of each fractionated treatment based on the gamma pass rate of the planned radiotherapy dose and the gamma pass rate of the actual radiotherapy dose. If the radiotherapy dose deviation is greater than the set threshold, a prompt message is sent to the user.

[0143] Through the above method, it is possible to view medical images, radiotherapy plan information and radiotherapy dose deviation in the same system, and notify the doctor in time when the radiotherapy dose deviation exceeds the set threshold or the registration deviation exceeds the set threshold. Therefore, the doctor can adjust the subsequent radiotherapy plan in time according to the medical image, radiotherapy dose deviation and / or registration deviation, solving the problem of not being able to display the results of multiple fractionated treatments on one interface.
