Description

Technical Field

[0001] This application relates to the field of radiotherapy, and in particular to a method, apparatus, computer device, and storage medium for generating supplementary radiotherapy plans. Background Technology

[0002] With the continuous development of computer technology, radiotherapy technology is also constantly maturing. Radiotherapy is a commonly used method for treating tumors. When radiotherapy is required, the patient first undergoes imaging at the hospital using medical imaging equipment. The physician delineates the target area of ​​the tumor in the patient's medical images and creates a treatment plan based on the target area. During treatment, the patient lies on the treatment table of the radiotherapy equipment, and the physician positions the patient according to the location of the tumor. After positioning, the radiotherapy equipment generates a beam to irradiate the patient's tumor area according to the formulated treatment plan. During the treatment, the radiotherapy equipment saves treatment records in real time. These records include basic patient information (name, age, and gender, etc.), information of the operating physician, the total dose during radiotherapy, the output dose of each radiation field, and the gantry rotation angle, among other data. Treatment records make the patient's information during treatment clearer; they also make it easier to find information when reviewing the treatment process later; and they improve the accuracy of radiotherapy.

[0003] During radiotherapy, equipment malfunctions or patient discomfort can sometimes lead to treatment interruptions. After an interruption, the patient is removed from the radiotherapy equipment for repair or sent home to rest. Once the equipment is repaired or the patient's discomfort subsides, supplementary treatment is administered according to the previous treatment plan. However, in some cases, the difference between the supplementary radiation dose and the remaining un-irradiated dose from the previous treatment plan can be significant, resulting in insufficient or excessive dose at the tumor site, causing harm to the patient.

[0031] Radiation therapy equipment is a device that treats tumors by irradiating them with radiation. Currently, radiation therapy equipment typically uses alpha, beta, and gamma rays, X-rays, electron beams, proton beams, and other particle beams generated by the equipment itself to irradiate tumor cells and kill them. To ensure precise location and accurate dosage for treatment, the process is as follows: First, the patient undergoes medical imaging in a positioning room. These images are transmitted to the radiation therapy planning system (TPS). The TPS system outlines the tumor based on the images and develops a treatment plan accordingly. This plan is then transmitted to the tumor radiotherapy information system (OIS), which schedules the treatment. The host computer of the radiation therapy equipment retrieves the corresponding treatment plan from the OIS based on the patient's information. Following the treatment plan, it controls the imaging system of the radiation therapy equipment to position the patient. After positioning, it controls the radiation source of the equipment to generate a beam to treat the patient.

[0032] A treatment plan is used to control the radiation beam generated by the radiotherapy equipment to treat the patient. A complete treatment plan includes multiple radiation fields, each covering a portion of the patient's tumor. All radiation fields work together to ensure that the dose received by the tumor area meets the treatment requirements. A single radiation field's treatment plan includes multiple control points that move continuously between each other, aiming to achieve a preset dose within each control point. The treatment plan for each control point includes: gantry position, the position of each leaflet of the MLC, dose percentage, and the total dose of the current radiation field.

[0033] During the treatment of patients according to the treatment plan, the radiotherapy equipment saves treatment records in real time and transmits these records back to the OIS system. The treatment records contain information such as physician information, completion information for each control point, and the actual radiation dose for each control point. When it is necessary to check the patient's condition during treatment, the corresponding treatment records can be retrieved. If the radiotherapy treatment is interrupted due to equipment failure or patient discomfort, the treatment record is interrupted, and the completed treatment records are transmitted back to the OIS system. In this case, if the actual radiation dose is greater than or equal to the preset dose in the radiotherapy plan, the corresponding control point has been irradiated; if the actual radiation dose is 0, the corresponding control point is incomplete; if the actual radiation dose is less than the preset dose in the radiotherapy plan, the corresponding control point is an interruption control point. This embodiment of the application can formulate a supplementary radiotherapy plan for the patient based on the treatment records transmitted back to the OIS after treatment interruption and the original treatment plan. This supplementary radiotherapy plan, by accurately obtaining the interruption control point information in the treatment records, can make the dose of the supplementary radiotherapy plan more precise, thereby avoiding damage to the patient during treatment.

[0034] This application provides a method for generating supplementary treatment plans. The method of this application can be applied in a computer device including a processor; for example, it can be applied in a server or a terminal device. Figure 1 This is a flowchart of a supplementary treatment plan generation method according to an embodiment of this application, such as... Figure 1 As shown, the process includes the following steps:

[0035] Step S100: Obtain the treatment records and original treatment plan of the subject to be irradiated.

[0036] A radiotherapy device irradiates the subject based on an original treatment plan. During treatment, irradiation may be interrupted due to various unforeseen circumstances. In this case, the subject needs to be removed from the radiotherapy device. Once the unforeseen circumstances are resolved, a supplementary irradiation plan needs to be generated for the subject based on the incomplete original treatment plan. This requires obtaining the subject's treatment record and the original treatment plan. The subject can be a human body, a phantom, an animal, or any substance to be irradiated by the radiotherapy device; this application does not impose specific limitations. The treatment record is a file sent back to the OIS system by the radiotherapy device after the irradiation interruption to record the treatment status. The original treatment plan is the treatment plan used when irradiating the subject during the irradiation interruption. For example, the treatment record and the original treatment plan can be obtained from the OIS system or from any storage medium; this application does not impose specific limitations.

[0037] Step S200: Based on the treatment records and the original treatment plan, determine the irradiated field, interrupted field, unirradiated field, and interruption control point.

[0038] After obtaining the treatment records and the original treatment plan, it is necessary to compare the treatment records and the original treatment plan to determine the interruption control point. Here, "irradiated field" refers to the field where the irradiation of the subject was completed before the radiotherapy equipment was interrupted; "interrupted field" refers to the field being executed when the radiotherapy equipment was interrupted; and "unirradiated field" refers to the field that has not yet been irradiated after the radiotherapy equipment was interrupted. The interruption control point is the control point in the interrupted field corresponding to the time of interruption. For example, it is necessary to obtain the actual radiation dose of each field based on the treatment records and the theoretical radiation dose of each field in the original treatment plan, and determine the irradiated field, interrupted field, and unirradiated field by comparison. Then, the corresponding interruption control point is determined in the interrupted field.

[0039] Step S300: Generate a supplementary irradiation treatment plan based on the irradiated field, interrupted field, unirradiated field, and interruption control point.

[0040] Retrieve the treatment plan corresponding to the irradiated fields from the treatment record; retrieve the treatment plans for all control points after the interruption control point in the original treatment plan. For example, based on the field where the interruption control point is located and its number, first locate the interruption control point in the original treatment plan. After finding the corresponding location of the interruption control point in the original treatment plan, extract the treatment plans for all control points after the interruption control point in the interrupted field, including the treatment plan for the corresponding interruption control point. Retrieve the treatment plan corresponding to the unirradiated fields in the original treatment plan. Based on the treatment record and the original treatment plan, adjust the treatment plan for the interrupted fields. Finally, generate a supplementary irradiation treatment plan by combining the treatment plans for the irradiated fields, the adjusted treatment plans for the interrupted fields, and the treatment plans for the unirradiated fields in the order of the original treatment plan. Through the final supplementary irradiation treatment plan, the unirradiated dose can be precisely controlled, and the overall dose received by the treated subject can be more accurate during supplementary irradiation.

[0041] This application embodiment obtains the treatment records and original treatment plan of the subject to be irradiated, and determines the irradiated field, interrupted field, unirradiated field, and interruption control point based on the treatment records and original treatment plan. Finally, a supplementary irradiation treatment plan is generated using the irradiated field, interrupted field, unirradiated field, and interruption control point. By accurately locating the irradiated field, interrupted field, and unirradiated field, and then determining the interruption control point based on the interrupted field, the final supplementary irradiation treatment plan can eliminate the gap between the supplementary irradiation dose and the remaining unirradiated dose, making the irradiation dose more accurate and avoiding damage to the patient during treatment.

[0042] This application also provides a method for determining an interrupt control point. Figure 2 This is a flowchart of a method for determining an interrupt control point according to an embodiment of this application, such as... Figure 2 As shown, the process includes the following steps:

[0043] Step S210: Compare the treatment record with the original treatment plan to obtain the irradiated field, interrupted field, and unirradiated field.

[0044] An interrupted field is the field in the original treatment plan that corresponds to the point in time when irradiation is interrupted. The treatment record contains the actual irradiation dose for each field, while the original treatment plan contains the theoretical irradiation dose for each field. The actual irradiation dose for each field is determined based on the treatment record, and the theoretical irradiation dose is determined based on the original treatment plan. If the actual irradiation dose of a field is greater than or equal to its theoretical irradiation dose, the corresponding field is considered an irradiated field. If the actual irradiation dose of a field is not zero but less than its theoretical irradiation dose, the corresponding field is considered an interrupted field. If the actual irradiation dose of a field is zero, the corresponding field is considered an unirradiated field. Regarding the dose in the treatment plan, when the treatment plan corresponds to the dose of the Gamma Knife device, the corresponding dose representation parameter is time, because the cobalt source beam dose is known, and the total dose can be obtained by combining the beam dose and time. When the treatment plan corresponds to the dose of the corresponding accelerator device, the corresponding dose representation parameter is the number of jumps, thus directly representing the dose.

[0045] Step S220: Determine the interruption control point in the interruption field based on the interruption field.

[0046] The treatment record shows the actual radiation dose at each control point, while the original treatment plan shows the total dose of the radiation field and the dose percentage at each control point. Multiplying the total dose of the radiation field in the original treatment plan by the dose percentage of the current control point yields the cumulative dose required for the current control point. Multiplying the total dose of the radiation field in the original treatment plan by the dose percentage of the previous control point yields the cumulative dose required for the previous control point. Subtracting the cumulative dose required for the previous control point from the cumulative dose required for the current control point gives the theoretical radiation dose required within the current control point. After determining the interrupted radiation field, the actual radiation dose at each control point within the interrupted field is compared with the theoretical radiation dose required for each control point. If the actual radiation dose at a control point is greater than or equal to the theoretical radiation dose, it is a completed control point; if the actual radiation dose at a control point is not zero but less than the theoretical radiation dose, it is an interrupted control point; if the actual radiation dose at a control point is zero, it is an untreated control point.

[0047] The embodiments of this application, through the above method, can accurately locate the interrupted radiation field, then determine the corresponding interruption control point within the interrupted radiation field, and generate a supplementary irradiation treatment plan by accurately identifying the interruption control point, thereby further making the supplementary irradiation dose planned in the supplementary irradiation treatment plan more precise.

[0048] This application also provides another method for generating supplementary treatment plans. Figure 3 This is a flowchart of a supplementary treatment plan generation method according to an embodiment of this application, such as... Figure 3 As shown, the process includes the following steps:

[0049] Step S310: Determine the remaining dose of the interrupted field based on the treatment records and the original treatment plan.

[0050] The treatment log records the actual radiation dose for each radiation field. After determining the interrupted radiation field, the actual radiation dose corresponding to the interrupted radiation field is read from the treatment plan; the theoretical radiation dose corresponding to the interrupted radiation field is read from the original treatment plan. Subtracting the corresponding actual radiation dose from the theoretical radiation dose yields the remaining dose of the interrupted radiation field.

[0051] Step S320: If the remaining dose of the interrupted field is less than the minimum dose of the device, and the interrupted field is the last field in the original treatment plan, set the status of the interrupted field to complete and set the status of the original treatment plan to complete.

[0052] If the remaining dose of the interrupted field is less than the minimum dose of the device, and the interrupted field is the last field in the original treatment plan, it means that the original treatment plan has been completed and no supplementary irradiation is required. Therefore, the status of the field corresponding to the interrupted field in the original treatment plan needs to be set to complete; then the status of the original treatment plan needs to be set to complete.

[0053] Step S330: If the remaining dose of the interrupted field is greater than or equal to the minimum dose of the device, or if the interrupted field is not the last field in the original treatment plan, generate a supplementary treatment plan based on the irradiated field, the interrupted field, the unirradiated field, and the interruption control point.

[0054] This application also provides another method for generating supplementary treatment plans. Figure 4 This is a flowchart of a supplementary treatment plan generation method according to an embodiment of this application, such as... Figure 4 As shown, the process includes the following steps:

[0055] Step S331: Determine the remaining irradiation dose at the interruption control point based on the treatment records and the original treatment plan.

[0056] Based on the treatment records, obtain the actual irradiation dose at the corresponding interruption control point. Calculate the theoretical irradiation dose at the interruption control point using the calculation method in step S220, according to the original treatment plan. Subtract the actual irradiation dose from the theoretical irradiation dose to obtain the remaining irradiation dose at the interruption control point. The remaining irradiation dose at the interruption control point represents the irradiation dose not received by the target at the interruption control point after the interruption.

[0057] Step S332: Determine the number of remaining control points in the corresponding field of attack based on the interrupted control point and the original treatment plan.

[0058] Based on the field where the interrupted control point is located and its number, first locate the interrupted field in the original treatment plan. Within the interrupted field, based on the control point's number, find the corresponding control point and calculate the number of remaining control points after the interrupted control point. For example, in an interrupted field with 72 control points numbered 0-71, when the control point number is 50, there are 21 remaining control points; when the control point number is 71, there are 0 remaining control points.

[0059] Step S333: Adjust the treatment plan for the interrupted field based on the remaining irradiation dose, the number of remaining control points, the treatment record, and the original treatment plan.

[0060] Based on the remaining irradiation dose and the number of remaining control points, the treatment plan corresponding to the interrupted irradiation field is updated using different modes to generate the final supplementary irradiation treatment plan. For example, if the number of remaining control points is zero and the remaining irradiation dose is less than the minimum dose of the device, the status of the treatment plan corresponding to the interrupted irradiation field is set to complete. Since the number of remaining control points is zero and the remaining irradiation dose is less than the minimum dose of the device, it indicates that the interrupted irradiation field has been irradiated, so the treatment plan for the interrupted irradiation field is set to complete, resulting in the supplementary irradiation treatment plan. If the number of remaining control points is zero and the remaining irradiation dose is greater than or equal to the minimum dose of the device, the treatment plan for the interrupted irradiation field is adjusted according to the treatment record and the original treatment plan using a first rule. If the number of remaining control points is greater than zero and the remaining irradiation dose is less than the minimum dose of the device, the treatment plan for the interrupted irradiation field is adjusted according to the treatment record and the original treatment plan using a second rule. If the number of remaining control points is greater than zero and the remaining irradiation dose is greater than or equal to the minimum dose of the device, the treatment plan for the interrupted irradiation field is adjusted according to the treatment record and the original treatment plan using a third rule.

[0061] Step S334: Generate a supplementary irradiation treatment plan based on the treatment plan for the irradiated field, the adjusted treatment plan for the interrupted field, and the treatment plan for the unirradiated field.

[0062] Generate a supplementary treatment plan by taking the treatment plans for the irradiated fields, the adjusted treatment plans for the interrupted fields, and the treatment plans for the unirradiated fields in the order of the original treatment plans.

[0063] This application embodiment generates supplementary irradiation treatment plans based on different modes. It can divide the treatment plan into multiple modes according to the execution status of the treatment plan during interruption. Different modes can be selected according to different situations to adjust the treatment plan of the interrupted field. This makes it more targeted to the interruption situation and further makes the supplementary irradiation dose planned in the supplementary irradiation treatment plan more accurate.

[0064] This application also provides a method for adjusting a treatment plan that interrupts the shooting field using a first rule. Figure 5 This is a flowchart of a method for adjusting a treatment plan that interrupts the firing field according to a first rule, as described in an embodiment of this application. Figure 5 As shown, the process includes the following steps:

[0065] Step S3331-a: Based on the original treatment plan, obtain the first control point information corresponding to the interruption control point and the second control point information of the control point above the interruption control point.

[0066] Based on the field of the interruption control point and its number, the location of the interruption control point is first determined in the original treatment plan. After finding the corresponding location of the interruption control point in the original treatment plan, the information of the first control point corresponding to the interruption control point is obtained, followed by the information of the second control point preceding the interruption control point. The control point information includes: the position of the multi-leaf grating blades, the gantry position, and the dose percentage, among other information.

[0067] Step S3332-a: Calculate the ratio of the irradiated dose at the interruption control point to the total dose at the interruption control point.

[0068] Multiply the total dose of the interrupted field in the original treatment plan by the dose percentage corresponding to the interruption control point to obtain the cumulative dose required to reach the interruption control point. Multiply the total dose of the interrupted field in the original treatment plan by the dose percentage of the control point preceding the interruption control point to obtain the cumulative dose required to reach the corresponding control point. Subtract the cumulative dose required to reach the previous control point from the cumulative dose required to reach the interruption control point to obtain the total dose required within the interruption control point. Obtain the irradiated dose of the interruption control point recorded in the treatment record, and calculate the ratio based on the irradiated dose of the interruption control point and the total dose of the interruption control point.

[0069] Step S3333-a: Add a new control point before the first control point of the interrupted shooting field, and update the information of the newly added control point according to the ratio, the information of the first control point and the information of the second control point.

[0070] Before interrupting the first control point of the radiation field, add a new control point. Then update the information for the new control point. Adjust the dose percentage of the new control point to 0. Adjust the position of each leaf of the multi-leaf grating at the new control point according to the following formula:

[0071] X = (X1 - X2) * A + X2

[0072] Where X is the position of the newly added control point leaf; X1 is the specified leaf position of the original treatment plan corresponding to the interruption control point; X2 is the planned leaf position of the original treatment plan corresponding to the control point preceding the interruption control point; and A is the ratio calculated in step S3332-a.

[0073] The above formula is a method for calculating the position of a leaf in a multi-leaf grating. Each leaf in the multi-leaf grating needs to be calculated using the above formula to determine its corresponding position and then updated in the new control point information.

[0074] Adjust the rack position of the newly added control point according to the following formula:

[0075] Y = (Y1 - Y2) * A + Y2

[0076] Where Y is the rack position of the newly added control point; Y1 is the rack position of the interrupted control point; Y2 is the rack position of the control point preceding the interrupted control point; and A is the ratio calculated in step S3332-a.

[0077] Step S3334-a: Adjust the percentage of dose at the remaining control points in the corresponding interrupted radiation field to 1, and adjust the total dose at the control points to the remaining irradiation dose.

[0078] The first rule assumes that the number of remaining control points is zero and the remaining radiation dose is greater than or equal to the minimum dose of the equipment. Therefore, in this case, there is only one remaining control point in the interrupted field, which is the interrupted control point. The dose percentage of this control point is adjusted to 1, and the total dose of the control point is adjusted to the calculated remaining radiation dose.

[0079] This application also provides a method for adjusting a treatment plan that interrupts the shooting field using a second rule. Figure 6 This is a flowchart of a method for adjusting a treatment plan that interrupts the firing field according to a second rule, as described in an embodiment of this application. Figure 6 As shown, the process includes the following steps:

[0080] Step S3331-b: Based on the original treatment plan, obtain the first control point information corresponding to the interruption control point and the second control point information of the control point above the interruption control point.

[0081] The specific example of this step is the same as the description in step S3331-a, and will not be repeated here.

[0082] Step S3332-b: Based on the treatment records and the original treatment plan, obtain the dose percentage of all control points in the interrupted field, the total dose of the interrupted field, and the irradiated dose of the interrupted field.

[0083] The second rule is predicated on the following conditions: the number of remaining control points is greater than zero, and the remaining irradiation dose is less than the minimum dose of the device. Therefore, in the original treatment plan, the corresponding interrupted field contains multiple remaining control points, which are the control points that have not been executed. The dose percentage for each unexecuted control point, the total dose of the interrupted field, and the irradiated dose of the interrupted field are obtained respectively.

[0084] Step S3333-b: Calculate the ratio of the irradiated dose at the interruption control point to the total dose at the interruption control point.

[0085] The specific example of this step is the same as the description in step S3332-a, and will not be repeated here.

[0086] Step S3334-b: Update the first control point information of the interrupted shooting field based on the ratio, the first control point information, and the second control point information.

[0087] Adjust the information of the first control point in the interrupted field. Set the dose percentage of the first control point to 0. Adjust the position of each leaf of the multi-leaf grating at the first control point according to the following formula:

[0088] X = (X1 - X2) * A + X2

[0089] Where X is the leaf position of the first control point; X1 is the specified leaf position of the original treatment plan corresponding to the interruption control point; X2 is the specified leaf position of the original treatment plan corresponding to the control point preceding the interruption control point; and A is the ratio calculated in step S3333-b.

[0090] The above formula is a method for calculating the position of a leaf in a multileaf grating. Each leaf in the multileaf grating needs to be calculated using the above formula to determine its corresponding position and then updated in the first control point information.

[0091] Adjust the rack position of the first control point according to the following formula:

[0092] Y = (Y1 - Y2) * A + Y2

[0093] Where Y is the rack position of the first control point; Y1 is the rack position of the interrupt control point; Y2 is the rack position of the control point preceding the interrupt control point; and A is the ratio calculated in step S3333-b.

[0094] Step S3335-b: Update the dose percentage of the corresponding control point based on the dose percentage of all control points, the total dose of the interrupted field, and the dose already irradiated in the interrupted field.

[0095] Since step S3332-b obtains the dose percentage of the multiple remaining control points (i.e., the control points that were not executed) within the corresponding interrupted firing field, this step only requires updating the dose percentage of the corresponding control points. In other words, it only requires updating the dose percentage of the remaining control points in the interrupted firing field, excluding the first control point. The dose percentage of the corresponding control points is updated according to the following formula:

[0096]

[0097] Where C is the dose percentage of the corresponding control point after the update; B is the dose percentage of the corresponding control point in the original treatment plan; Q is the total dose of the interrupted field; and P is the irradiated dose of the interrupted field.

[0098] This application also provides a method for adjusting a treatment plan that interrupts the shooting field using a third rule. Figure 7 This is a flowchart of a method for adjusting a treatment plan that interrupts the firing field according to an embodiment of this application, such as... Figure 7 As shown, the process includes the following steps:

[0099] Step S3331-c: Based on the original treatment plan, obtain the first control point information corresponding to the interruption control point and the second control point information of the control point above the interruption control point.

[0100] The specific example of this step is the same as the description in step S3331-a, and will not be repeated here.

[0101] Step S3332-c: Based on the treatment records and the original treatment plan, obtain the dose percentage of all control points in the interrupted field, the total dose of the interrupted field, and the irradiated dose of the interrupted field.

[0102] The prerequisite for the third rule is that the number of remaining control points is greater than zero, and the remaining irradiation dose is greater than or equal to the minimum dose of the device. Therefore, in the original treatment plan, the corresponding interrupted field contains multiple remaining control points, which are control points that have not been executed. The dose percentage for each unexecuted control point, the total dose of the interrupted field, and the irradiated dose of the interrupted field are obtained respectively.

[0103] Step S3333-c: Calculate the ratio of the irradiated dose at the interruption control point to the total dose at the interruption control point.

[0104] The specific example of this step is the same as the description in step S3332-a, and will not be repeated here.

[0105] Step S3334-c: Add a new control point before the first control point of the interrupted shooting field, and update the information of the newly added control point based on the ratio, the information of the first control point, and the information of the second control point.

[0106] The specific example of this step is the same as the description in step S3333-a, and will not be repeated here.

[0107] Step S3335-c: Update the dose percentage of the corresponding control point based on the dose percentage of all control points, the total dose of the interrupted field, and the dose already irradiated in the interrupted field.

[0108] Since step S3332-c obtains the dose percentages of multiple remaining control points (i.e., control points that were not executed) within the firing field corresponding to the interrupted control point, this step only requires updating the dose percentages of the corresponding control points. In other words, it only requires updating the dose percentages of all control points in the firing field corresponding to the interrupted control point. The dose percentages of the corresponding control points are updated according to the following formula:

[0109]

[0110] Where C is the dose percentage of the corresponding control point after the update; B is the dose percentage of the corresponding control point in the original treatment plan; Q is the total dose of the interrupted field; and P is the irradiated dose of the interrupted field.

[0111] In this embodiment, based on the remaining irradiation dose and the number of remaining control points at the time of interruption, supplementary irradiation is divided into several cases. Different rules are applied to each case to adjust the treatment plan for the interrupted irradiation field, ensuring the accuracy of the remaining dose irradiation and avoiding damage to the patient during treatment.

[0112] It should be noted that the steps shown in the above process or in the flowchart of the accompanying figures can be executed in a computer system such as a set of computer-executable instructions, and although a logical order is shown in the flowchart, in some cases the steps shown or described may be executed in a different order than that shown here.
