Description

Technical Field

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

[0002] Radiation therapy is a localized radiotherapy method that uses radiation to kill tumor cells. Arc irradiation, as a type of radiation therapy, involves rotating a radiation source around the isocenter of the radiation device in an arc. The radiation rays pass through healthy tissue via a non-fixed path, dispersing the radiation dose to healthy tissue and protecting it, while the isocenter lesions receive the maximum dose. Current radiation therapy technology supports single-circle radiotherapy, meaning continuous arc irradiation along the same direction from 0 to 360 degrees. However, when a patient's treatment plan requires continuous arc irradiation exceeding 360 degrees along the same direction—that is, multi-circle radiotherapy—current radiation therapy technology cannot rationally or individually plan multiple sub-treatment plans; each sub-treatment plan must be executed individually. Therefore, how to achieve rational planning of multiple sub-treatment plans is an urgent problem to be solved. Summary of the Invention

[0003] This application provides a method, system, device, and storage medium for generating treatment plans, which can rationally plan multiple single-loop / multi-loop sub-treatment plans without having to execute them individually; furthermore, it can also achieve arc irradiation of more than 360 degrees and the planning of personalized treatment plans.

[0036] The descriptions of aspects two through ten in this application can be referenced to the detailed descriptions of aspects one or four; and the beneficial effects of the descriptions of aspects two through ten can be referenced to the analysis of the beneficial effects of aspects one or four, which will not be repeated here.

[0037] In this application, the names of the treatment plan generation device and the radiotherapy device do not limit the equipment or functional module itself. In actual implementation, these devices or functional modules may appear under other names.

Since the target treatment plan is obtained by cascading multiple sub-treatment plans, compared to the current problem of excessively long switching times caused by multiple switching between sub-treatment plans when executing multiple sub-treatment plans, this technical solution eliminates the need for switching between multiple sub-treatment plans; treatment can be completed by executing a single target treatment plan, greatly improving treatment efficiency.

[0041] Furthermore, since the target treatment plan is obtained by cascading multiple sub-treatment plans, when the aforementioned control equipment performs radiotherapy on the target subject based on the target treatment plan, it can provide different treatment plans (such as different treatment doses, treatment angles, etc.) for different parts of the target subject according to the nature of the lesions, so as to make the treatment more precise and optimize the treatment effect.

[0054] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0055] In this article, the term "and / or" is merely a description of the relationship between related objects, indicating that there can be three relationships. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone.

[0056] The terms "first" and "second," etc., used in the specification and drawings of this application are used to distinguish different objects or to distinguish different treatments of the same object, rather than to describe a specific order of objects.

[0057] Furthermore, the terms "comprising" and "having," and any variations thereof, used in the description of this application are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the steps or units listed, but may optionally include other steps or units not listed, or may optionally include other steps or units inherent to such process, method, product, or apparatus.

[0058] It should be noted that in the embodiments of this application, the words "exemplary" or "for example" are used to indicate examples, illustrations, or explanations. Any embodiment or design scheme described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design schemes. Specifically, the use of the words "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

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

[0060] The following explanations of the terms used in the embodiments of this application are provided to facilitate the reader's understanding.

[0061] (1) Radiotherapy.

[0062] Single-circle radiotherapy uses a radiation source that moves in a circular motion around a fixed central axis within a plane to deliver a single arc of radiation around the patient's body, concentrating the radiation at the target site (e.g., a tumor) from different angles. Single-circle radiotherapy maximizes the radiation dose to the tumor while minimizing damage to surrounding healthy tissues by precisely controlling the angle of incidence and dose distribution of the radiation.

[0063] Multi-coil radiotherapy refers to a method of irradiating the target tumor by rotating the radiation source along multiple circular orbits of different radii or on different planes. Examples include intensity-modulated radiation therapy (IMRT) and volumetric modulated arc therapy (VMAT). Multi-coil radiotherapy can irradiate the target tumor (e.g., a tumor) from multiple angles with varying dose weights, based on the shape and size of the target. This ensures a more uniform distribution of radiation dose within the target, improving control over the tumor. Furthermore, multi-coil radiotherapy is better suited to tumors with complex shapes and irregular boundaries. By adjusting the field angles and dose distribution, the high-dose zone closely matches the overall tumor height, further reducing the radiation dose to surrounding normal tissues.

[0064] In the field of radiotherapy, the radiation field is a fundamental parameter in radiotherapy planning. Specifically, the radiation field refers to the area on the patient where the radiation beam originates from the radiation source, is confined by collimators and other equipment, and ultimately irradiates the patient. It defines the range and direction of radiation exposure and is a basic parameter in radiotherapy planning.

[0065] The terms used in the embodiments of this application have been introduced above. The application scenarios of the embodiments of this application will be described below.

[0066] Radiation therapy is a localized radiotherapy method that uses radiation to kill tumor cells. Arc irradiation, as a type of radiation therapy, involves rotating a radiation source around the isocenter of a radiation device in an arc. The radiation rays pass through healthy tissue via a non-fixed path, dispersing the radiation dose to healthy tissue and protecting it, while the isocenter lesions receive the maximum dose. Current radiation therapy technology supports single-circuit radiotherapy, meaning continuous arc irradiation along the same direction from 0 to 360 degrees. However, when a patient's treatment plan requires continuous arc irradiation along the same direction exceeding 360 degrees—that is, when multiple-circuit radiotherapy is needed—current radiation therapy technology cannot rationally or individually plan multiple sub-treatment plans (e.g., multiple single-circuit / multi-circuit sub-treatment plans). Each sub-treatment plan must be executed individually. Therefore, how to achieve rational planning of multiple sub-treatment plans is a problem that urgently needs to be solved.

[0067] Based on the above technical solution, the treatment plan generation method provided in this application can acquire and parse the medical records of the target subject to generate multiple sub-treatment plans; then, according to the identification information of each sub-treatment plan, the multiple sub-treatment plans are linked together into a target treatment plan. The multiple sub-treatment plans include single-circle treatment plans and / or multi-circle treatment plans. In other words, this technical solution can rationally or individually plan and link multiple sub-treatment plans without requiring them to be executed one by one, thus enabling arc irradiation exceeding 360 degrees.

[0068] Furthermore, based on the above technical solution, the radiotherapy system provided in this application includes a radiotherapy planning device, a radiotherapy device, and a control device. The radiotherapy planning device is used to issue a target treatment plan; the radiotherapy device includes a continuously rotatable gantry and a radiation source mounted on the gantry, and the gantry can drive the radiation source to rotate around the target object. The control device can receive the target treatment plan generated by the treatment plan generation method provided in this application embodiment, and control the radiation source to emit a radiation beam towards the target area of ​​the target object based on the target treatment plan. Since the target treatment plan is obtained by cascading multiple sub-treatment plans, compared to the current problem of excessively long switching times caused by multiple switching between sub-treatment plans when executing multiple sub-treatment plans, this technical solution eliminates the need for switching between multiple sub-treatment plans; treatment can be completed by executing a single target treatment plan, greatly improving treatment efficiency.

[0069] Furthermore, since the target treatment plan is obtained by cascading multiple sub-treatment plans, when the aforementioned control equipment performs radiotherapy on the target subject based on the target treatment plan, it can provide different treatment plans (such as different treatment doses, treatment angles, etc.) for different parts of the target subject according to the nature of the lesions, so as to make the treatment more precise and optimize the treatment effect.

[0070] The embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0071] It should be noted that the various embodiments of this application can be referenced or learned from each other. For example, the same or similar steps, method embodiments, system embodiments and device embodiments can be referenced from each other without limitation.

[0072] The following, combined with Figures 1-3 The method for generating treatment plans is described in detail.

[0073] Figure 1 A flowchart illustrating a method for generating a treatment plan, as provided in an embodiment of this application. Figure 1 As shown, the method includes the following S101-S102.

[0074] S101. Obtain the medical records of the target object, parse the medical records, and generate multiple sub-treatment plans.

[0075] The multiple sub-treatment plans include single-circle treatment plans and / or multi-circle treatment plans. A single-circle treatment plan specifically involves performing a single-circle radiation therapy around the target subject; a multi-circle treatment plan specifically involves performing multiple-circle radiation therapy around the target subject.

[0076] For a detailed explanation of single-circle radiotherapy and multi-circle radiotherapy, please refer to the glossary section of the embodiments of this application, which will not be repeated here.

[0077] Optionally, the sub-treatment plan can be applied to a linear accelerator or Gamma Knife. Of course, the above is only an exemplary description of the application scenarios of the sub-treatment plan. The sub-treatment plan can also be applied to treatment devices such as proton therapy devices, electronic therapy machines, cobalt-60 therapy machines, and CyberKnife. This application does not impose any limitations on this.

[0078] Optionally, the medical record of the target subject may include multiple sub-treatment plans corresponding to the target subject and the target subject's medical information (for example, the medical information may be the target subject's patient information and medical team information, etc.).

[0079] In one possible implementation, the process of S101 includes: after obtaining the medical records of the target object, performing data cleaning and format standardization on the medical records, and then parsing the medical records to obtain multiple format-standardized sub-treatment plans. Alternatively, before obtaining the medical records of the target object, data cleaning and format standardization can be performed on the medical records of the target object, that is, the obtained medical records of the target object are medical records that have undergone data cleaning and format standardization.

[0080] In summary, this application does not limit the execution order of data cleaning and format standardization processing of the target object's medical records. It can be performed after or before obtaining the target object's medical records.

[0081] S102. Determine the identification information of each sub-treatment plan, and link multiple sub-treatment plans into a target treatment plan based on the identification information of each sub-treatment plan.

[0082] In one possible implementation, the identification information includes the execution order of the sub-treatment plans within the target treatment plan.

[0083] In one example, where multiple sub-treatment plans are all single-circle treatment plans, the identification information specifically includes the execution order of each single-circle treatment plan.

[0084] For example, consider multiple sub-treatment plans, including a first single-circle treatment plan and a second single-circle treatment plan. The identification information specifies that the execution order of the first single-circle treatment plan is "first," and the execution order of the second single-circle treatment plan is "second."

[0085] In another example, consider multiple sub-treatment plans, including single-circle and multi-circle treatment plans. The identification information specifically includes the execution order of the single-circle treatment plan and the execution order of each circle treatment plan within the multi-circle treatment plan.

[0086] For example, consider a treatment plan consisting of single-circle and multi-circle plans, where the multi-circle plan is a two-circle plan. The identification information specifies that the execution order of the single-circle plan is first, the execution order of the first circle plan in the multi-circle plan is second, and the execution order of the second circle plan is third.

[0087] In another example, consider multiple sub-treatment plans that include multiple multi-circle treatment plans. The identification information would specifically include the execution order of each circle treatment plan within each multi-circle treatment plan.

[0088] For example, consider a multi-circle treatment plan comprising a first multi-circle treatment plan and a second multi-circle treatment plan, where the first multi-circle treatment plan is a two-circle plan and the second multi-circle treatment plan is a three-circle plan. The identification information specifies that the execution order of the first circle treatment plan within the first multi-circle treatment plan is first, and the execution order of the second circle treatment plan is second; and the execution order of the first circle treatment plan within the second multi-circle treatment plan is third, the execution order of the second circle treatment plan is fourth, and the execution order of the third circle treatment plan is fifth.

[0089] In another possible implementation, the identification information may also include a treatment plan identifier for each sub-treatment plan. Furthermore, if the sub-treatment plan is a multi-circle treatment plan, the identification information may also include an identifier indicating the circle number of each circle within the multi-circle treatment plan.

[0090] In some embodiments, the identification information of each sub-treatment plan is determined in S102. The specific implementation process of connecting multiple sub-treatment plans into a target treatment plan based on the identification information of each sub-treatment plan can be referred to the embodiments shown in S201-S202, and will not be repeated here.

[0091] It should be noted that after generating multiple sub-treatment plans, and before concatenating these sub-treatment plans into a target treatment plan, it is necessary to first determine the identification information of the sub-treatment plans so that they can be concatenated according to the identification information in the future.

[0092] Based on the above technical solution, the treatment plan generation method provided in this application can acquire and parse the medical records of the target patient to generate multiple sub-treatment plans; then determine the identification information of each sub-treatment plan, and connect the multiple sub-treatment plans into a target treatment plan based on the identification information of each sub-treatment plan. The multiple sub-treatment plans include single-circle treatment plans and / or multi-circle treatment plans. In other words, this technical solution can rationally or individually plan and connect multiple sub-treatment plans without having to execute them one by one, thus enabling arc irradiation exceeding 360 degrees.

[0093] As one possible embodiment of this application, combined with Figure 1 ,like Figure 2 As shown, the process of determining the identification information of each sub-treatment plan in S102 above, and connecting multiple sub-treatment plans into a target treatment plan based on the identification information of each sub-treatment plan, can be achieved through the following S201-S202.

[0094] S201. Determine the identification information of each sub-treatment plan, and determine the sequence of multiple sub-treatment plans based on the identification information of each sub-treatment plan.

[0095] In one possible implementation, the implementation process of S201 includes: determining the identification information of each sub-treatment plan, corresponding to the execution order of the sub-treatment plan in the target treatment plan included in the identification information, and determining the serial order between multiple sub-treatment plans according to the execution order and the execution rules of the target treatment plan.

[0096] The execution rules for the target treatment plan refer to execution in either sequential order or in reverse sequential order.

[0097] In one example, consider multiple sub-treatment plans, each consisting of two single-circle treatment plans, where the identification information specifies the execution order of the first single-circle treatment plan as "first" and the second single-circle treatment plan as "second." If the execution rule is sequential, then the sequential order of the first single-circle treatment plan (executed first) is determined to be "first," and the sequential order of the second single-circle treatment plan (executed second) is determined to be "second." If the execution rule is reverse, then the sequential order of the second single-circle treatment plan (executed second) is determined to be "first," and the sequential order of the first single-circle treatment plan (executed first) is determined to be "second."

[0098] In another example, consider a multi-circle treatment plan comprising a single-circle treatment plan and a multi-circle (two-circle) sub-treatment plan. The identification information specifies that the single-circle treatment plan is executed first, the first circle treatment plan in the multi-circle plan is executed second, and the second circle treatment plan is executed third. If the execution rule is sequential, then the sequence order of the single-circle treatment plan (execution first) is determined to be first, the sequence order of the first circle treatment plan (execution second) is second, and the sequence order of the second circle treatment plan (execution third) is third.

[0099] In another possible implementation, the implementation process of S201 specifically includes: determining the identification information of each sub-treatment plan, which may also include the treatment plan identifier (also called beamID) of each sub-treatment plan and the circle number identifier (also called Circle Number) of each circle treatment plan; then determining the sequence order between each circle treatment plan in the multi-circle treatment plan based on the circle number identifier of each circle treatment plan in the multi-circle treatment plan; and determining the sequence order between multiple sub-treatment plans based on the treatment plan identifiers of multiple sub-treatment plans.

[0100] In other words, the sequential order of multiple sub-treatment plans is determined by the treatment plan identifier. Furthermore, when multiple sub-treatment plans include multi-round treatment plans, the sequential order of each round treatment plan is determined by the round number identifier of each round treatment plan.

[0101] It should be noted that the treatment plan identifiers differ between different single-circle treatment plans; within a multi-circle treatment plan, the treatment plan identifier is the same for each circle, but the circle number identifier differs. Therefore, for multi-circle treatment plans, the sub-treatment plan for any circle can be accurately identified by using both the treatment plan identifier and the circle number identifier. For single-circle treatment plans, the treatment plan identifier alone is sufficient for identification.

[0102] In one example, multiple sub-treatment plans include one single-circle treatment plan and one multi-circle (two-circle) sub-treatment plan. The sequence order between the single-circle treatment plan identifier and the multi-circle treatment plan identifier is determined using the treatment plan identifiers of the single-circle and multi-circle treatment plans. Furthermore, the sequence order between the first and second circle treatment plans is determined using the circle number identifiers of the first and second circle treatment plans within the multi-circle treatment plan.

[0103] S202. Based on the serial order, perform serial processing on each serial object in multiple sub-treatment plans to obtain the target treatment plan.

[0104] Optionally, corresponding to a sub-treatment plan applied to a linear accelerator, the serial objects include the blade position, gantry angle, and gantry rotation speed during the execution of the sub-treatment plan.

[0105] Optionally, corresponding to a sub-treatment plan applied to Gamma Knife, the serialized objects include the gantry angle, gantry rotation speed, arc start point, and arc end point during the execution of the sub-treatment plan. The serialized objects may also include the treatment time of the sub-treatment plan.

[0106] In one possible implementation, the process of performing concatenation processing on each concatenated object in multiple sub-treatment plans in S202 may include: performing concatenation processing on concatenated objects of the same type in multiple sub-treatment plans according to the type of the concatenated object.

[0107] In one example, multiple sub-treatment plans include a first sub-treatment plan and a second sub-treatment plan. The first sub-treatment plan contains parameters such as blade position, rack angle, and rack rotation speed during execution of the sub-treatment plan; the second sub-treatment plan also contains parameters such as blade position, rack angle, and rack rotation speed during execution of the sub-treatment plan. The blade positions in the first and second sub-treatment plans are concatenated; the rack angles in the first and second sub-treatment plans are concatenated; and the rack rotation speeds in the first and second sub-treatment plans are concatenated.

[0108] Based on the above technical solution, the sequence of multiple sub-treatment plans is determined according to the identification information of each sub-treatment plan. Based on the sequence, a personalized target treatment plan can be obtained by performing series processing on each series object in the multiple sub-treatment plans, which facilitates subsequent implementation of arc irradiation exceeding 360 degrees.

[0109] As one possible embodiment of this application, such as Figure 3 As shown, the method for generating a treatment plan, including an image-guided approach, may include the following steps S301-S302, for the process of determining a target treatment plan.

[0110] S301. Analyze the medical records of the target patient, obtain the corresponding imaging information, and generate multiple sub-treatment plans including image-guided protocols.

[0111] The multiple sub-treatment plans include single-circle treatment plans and / or multi-circle treatment plans. The influence-guided protocol is a protocol generated based on image information.

[0112] It should be noted that imaging information refers to the scanning range and field of view determined by imaging techniques before radiotherapy. This information encompasses the target object (e.g., a tumor) and the surrounding tissues and other organs that may be affected by radiation. Image-guided protocols facilitate medical personnel in diagnosing the location, size, shape, and relationship between the target object and surrounding structures. Furthermore, image-guided protocols allow for precise location of the target area, ensuring accurate irradiation of the target with minimal protection of surrounding healthy tissues.

[0113] In one possible implementation, analyzing the patient's medical records can yield image-guided treatment plans and at least one single-circle treatment plan and / or a multi-circle treatment plan.

[0114] For example, analyzing the patient's medical records yields an image-guided treatment plan and at least one single-circle treatment plan; or, an image-guided treatment plan and at least one multi-circle treatment plan; or, an image-guided treatment plan, at least one single-circle treatment plan, and at least one multi-circle treatment plan.

[0115] S302. Determine the identification information of each sub-treatment plan that includes an image-guided approach, and based on the identification information of each sub-treatment plan that includes an image-guided approach, link multiple sub-treatment plans together into a target treatment plan that includes an image-guided approach.

[0116] Optionally, the identification information may include the image-guided protocol and the execution order of multiple sub-treatment plans.

[0117] In one possible implementation, the specific implementation process of S302 includes: determining the execution order of the image-guided plan and multiple sub-treatment plans; determining the concatenation order between the image-guided plan and multiple sub-treatment plans based on the execution order; and performing concatenation processing on each concatenated object in the image-guided plan and multiple sub-treatment plans based on the concatenation order to obtain the target treatment plan.

[0118] For example, consider a multi-circle treatment plan comprising an image-guided treatment scheme, a single-circle treatment plan, and a two-circle treatment plan, with the execution order of the image-guided treatment scheme as first, the single-circle treatment plan as second, the first circle treatment plan in the multi-circle treatment plan as third, and the second circle treatment plan as fourth. Based on the execution order of the image-guided treatment scheme, the single-circle treatment plan, and the two-circle treatment plan, the concatenation order among them is determined (e.g., the concatenation order could be: image-guided treatment scheme as first, single-circle treatment plan as second, first circle treatment plan in the multi-circle treatment plan as third, and second circle treatment plan as fourth). Then, based on this concatenation order, each concatenated object in the image-guided treatment scheme, the single-circle treatment plan, the first circle treatment plan, and the second circle treatment plan is concatenated to obtain the target treatment plan.

[0119] The process of connecting the various connected objects to obtain the target treatment plan is described in the embodiment shown in S202, and will not be repeated here.

[0120] Based on the above technical solution, the medical records of the target patient are analyzed to obtain corresponding imaging information, generating multiple sub-treatment plans, each including an image-guided protocol. Then, the identification information of each sub-treatment plan is determined. Based on the identification information of each sub-treatment plan, the multiple sub-treatment plans are concatenated into a target treatment plan that includes an image-guided protocol. Since the target treatment plan obtained here includes an image-guided protocol, this plan can accurately locate the area of ​​the target patient during execution, ensuring that radiation can accurately irradiate the target patient while maximizing the protection of surrounding healthy tissue.

[0121] This application embodiment can divide the treatment plan generation device into functional modules or functional units according to the above method example. For example, each function can be divided into a separate functional module or functional unit, or two or more functions can be integrated into one processing module. The integrated module can be implemented in hardware or in software functional modules or functional units. The module or unit division in this application embodiment is illustrative and only represents one logical functional division; other division methods may be used in actual implementation.

[0122] The following is a detailed introduction to the treatment plan generation system.

[0123] In some embodiments, the treatment plan generation method shown in this application can be applied to a treatment plan generation system. The treatment plan generation system includes: one or more processors; a memory; and one or more application programs.

[0124] One or more applications are stored in memory and configured to be executed by a processor using the method for generating a treatment plan as described in the above method embodiments.

[0125] In some embodiments, the treatment plan generation system is used to, in response to a medical record issuance instruction, obtain the medical record of the target object, parse the medical record, and generate multiple sub-treatment plans; in response to a treatment plan generation instruction, determine the identification information of each sub-treatment plan, and concatenate the multiple sub-treatment plans into a target treatment plan based on the identification information of each sub-treatment plan; wherein, the multiple sub-treatment plans include single-circle treatment plans and / or multi-circle treatment plans.

[0126] Optional, such as Figure 4 As shown, the processor in the treatment plan generation system responds to the instructions issued by the medical record and can obtain the target medical record (i.e., multiple scheduled sub-treatment plans and / or image-guided protocols corresponding to the target patient) from the oncology information system (OIS). The processor then parses the medical record and concatenates the multiple scheduled sub-treatment plans and / or image-guided protocols in the medical record to obtain the target treatment plan.

[0127] For example, consider a case where a medical record includes an image-guided treatment plan, and multiple sub-treatment plans include single-circle and / or multi-circle treatment plans. The image-guided treatment plan and the single-circle treatment plan can be concatenated, or the image-guided treatment plan and the multi-circle treatment plan can be concatenated, or the image-guided treatment plan, the single-circle treatment plan, and the multi-circle treatment plan can be concatenated.

[0128] For example, such as Figure 4As shown, the identification information (treatment plan identifier + circle number identifier) ​​for the concatenated image-guided plan and single-circle treatment plan is: Image-guided plan identifier 1 + circle number 1, sub-treatment plan identifier 2 + circle number 1. The identification information (treatment plan identifier + circle number identifier) ​​for the concatenated image-guided plan and 4-circle treatment plan is: Image-guided plan identifier 1 + circle number 1, sub-treatment plan identifier 2 + circle number 1, sub-treatment plan identifier 2 + circle number 2, sub-treatment plan identifier 2 + circle number 3, sub-treatment plan identifier 2 + circle number 4. The identification information (treatment plan identifier + circle number identifier) ​​for the concatenated image-guided plan, single-circle treatment plan, and 4-circle treatment plan is: Image-guided plan identifier 1 + circle number 1, sub-treatment plan identifier 2 + circle number 1, sub-treatment plan identifier 3 + circle number 1, sub-treatment plan identifier 3 + circle number 2, sub-treatment plan identifier 3 + circle number 3, sub-treatment plan identifier 3 + circle number 4.

[0129] The radiotherapy information management system is used to schedule each sub-treatment plan.

[0130] Optionally, the process by which the above-mentioned treatment plan generation system retrieves the target-related medical record from the radiotherapy information management system may include: such as Figure 4 As shown, the treatment planning system creates medical records for the target patient. Then, the system can send these records to the radiotherapy information management system. Subsequently, the system schedules the individual sub-treatment plans within the medical record and distributes the scheduled records to the treatment plan generation system.

[0131] The following, combined with Figure 5 The device for generating treatment plans is described in detail. For example... Figure 5 The diagram shown is a structural schematic of a treatment plan generation device 50 provided in an embodiment of this application. The treatment plan generation device 50 includes a communication unit 501 and a processing unit 502.

[0132] The communication unit 501 is used to acquire the medical records of the target object, parse the medical records, and generate multiple sub-treatment plans; the processing unit 502 is used to determine the identification information of each sub-treatment plan, and connect the multiple sub-treatment plans into a target treatment plan based on the identification information of each sub-treatment plan; wherein, the multiple sub-treatment plans include single-circle treatment plans and / or multi-circle treatment plans.

[0133] In one possible implementation, the identification information includes the execution order of the sub-treatment plans within the target treatment plan.

[0134] In one possible implementation, the processing unit 502 is specifically configured to: determine the identification information of each sub-treatment plan; determine the concatenation order among multiple sub-treatment plans based on the identification information of each sub-treatment plan; and perform concatenation processing on each concatenated object in the multiple sub-treatment plans based on the concatenation order to obtain the target treatment plan; wherein, for the process of performing concatenation processing on each concatenated object in the multiple sub-treatment plans, the processing unit 502 is specifically configured to perform concatenation processing on concatenated objects of the same type in the multiple sub-treatment plans according to the type of the concatenated object.

[0135] In one possible implementation, corresponding to a sub-treatment plan applied to a linear accelerator, the serialized objects include the blade position, gantry angle, and gantry rotational speed during the execution of the sub-treatment plan; corresponding to a sub-treatment plan applied to a gamma knife, the serialized objects include the gantry angle, gantry rotational speed, arc start point, and arc end point during the execution of the sub-treatment plan.

[0136] In one possible implementation, the processing unit 502 is further configured to: parse the medical records of the target object, obtain the corresponding image information, and generate multiple sub-treatment plans including image-guided schemes; and, based on the identification information of each sub-treatment plan including an image-guided scheme, concatenate the multiple sub-treatment plans into a target treatment plan including an image-guided scheme; wherein the multiple sub-treatment plans include single-circle treatment plans and / or multi-circle treatment plans.

[0137] In one possible implementation, the treatment plan generation device 50 may further include a storage unit 503. Figure 5 (shown in dashed box) The storage unit 503 stores a program or instruction. When the processing unit 502 executes the program or instruction, the treatment plan generation device 50 can perform the treatment plan generation method described in the above method embodiment.

[0138] The following, combined with Figure 6 This section provides a detailed introduction to radiotherapy systems.

[0139] Figure 6 This is a schematic diagram of the architecture of a radiotherapy system provided in an embodiment of this application. Figure 6 As shown, the radiotherapy system includes: a control device 601, a radiotherapy device 602, and a radiotherapy planning device 603.

[0140] In some embodiments, a radiotherapy planning device is a device for acquiring and analyzing medical records to develop, optimize, evaluate, and distribute treatment plans. This radiotherapy planning device may run a treatment planning system (TPS) that provides functions for developing, optimizing, and distributing evaluation radiotherapy plans. For example, the RT pro TPS system.

[0141] In some embodiments, the radiotherapy planning equipment may include a TPS client and a TPS server.

[0142] The TPS client can be at least one of the following devices: smartphone, smartwatch, desktop computer, laptop, virtual reality terminal, augmented reality terminal, wireless terminal, and laptop computer. For example, in some embodiments, a user can trigger the TPS server to execute an adaptive radiotherapy planning optimization process by running a radiotherapy planning system on the TPS server through the TPS client, and then display the optimized radiotherapy plan. This effectively saves user time and provides a more intuitive presentation of the optimized treatment plan, allowing users to evaluate the radiotherapy plan.

[0143] The TPS server can be a standalone physical server, a server cluster consisting of multiple physical servers, a distributed file system, or at least one of the following cloud servers providing basic cloud computing services: cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communication, middleware services, domain name services, security services, content delivery networks, and big data or artificial intelligence platforms. This application embodiment does not limit the specific type of TPS server. In some embodiments, the number of TPS servers can be more or less, and this application embodiment does not limit the specific type of TPS server. Of course, the TPS server can also include other functions to provide more comprehensive and diverse services. In some embodiments, the TPS server is used to provide backend services for the TPS client, such as the process of concatenating various sub-treatment plans.

[0144] In one possible implementation, the radiotherapy planning device may also run the aforementioned treatment plan generation system, through which a target treatment plan is generated and distributed.

[0145] In some embodiments, a control device 601 is used to receive a target treatment plan and, based on the target treatment plan, control a radiation source to emit a radiation beam toward the target area of ​​a target object. A radiotherapy device 602 includes a continuously rotatable gantry and a radiation source mounted on the gantry. The gantry is capable of driving the radiation source to rotate around the target object. A radiotherapy planning device 603 is used to issue the target treatment plan.

[0146] The control device 601 and the radiotherapy device 602 are connected via a communication link, and the control device 601 and the radiotherapy planning device 603 are also connected via a communication link. This communication link can be a wired communication link or a wireless communication link; this application does not limit the type of link.

[0147] The control device 601 will be described in detail below.

[0148] In one possible implementation, the control device 601 is specifically used to receive a target treatment plan from the radiotherapy planning device 603 and control the radiation source to emit a radiation beam toward the target area of ​​the target object based on the target treatment plan.

[0149] In another possible implementation, control device 601 is specifically used to receive a target treatment plan, including an image-guided protocol, from radiotherapy planning device 603. Based on the target treatment plan including the image-guided protocol, control device 601 can, based on user selection, execute the image-guided protocol and then execute the individual sub-treatment plans within the target treatment plan, controlling the radiation source to emit a radiation beam toward the target area of ​​the target object.

[0150] Alternatively, the control device 601 can also, based on user selection, execute the target treatment plan directly without executing the image-guided protocol, and control the radiation source to emit a radiation beam toward the target area of ​​the target object.

[0151] In one example, such as Figure 7 As shown, based on user selection (wherein, user selection can be implemented in the form of image guidance information), an image guidance scheme is executed, and after the image guidance scheme is completed, the system automatically jumps to execute the target treatment plan; or, if the image guidance scheme is not executed, the target treatment plan is executed directly in response to the user's trigger operation on the automatic treatment button (e.g., entering the user's account and password). Furthermore, in response to the user's trigger operation on the ready button in the control device 601, the radiation source is controlled to emit a radiation beam towards the target area of ​​the target object based on the target treatment plan.

[0152] In some embodiments, the control device 601 includes an automatic treatment button.

[0153] Optionally, in response to a user's triggering of the automatic treatment button, the control device 601 controls the radiation source to emit a radiation beam toward the target area of ​​the target object based on the target treatment plan.

[0154] Optionally, when a chain / lock situation is detected in the radiotherapy system, in response to the user's treatment termination command, the automatic treatment button is controlled to be in an untriggerable state (e.g., the automatic treatment button is grayed out, and in the grayed-out state, the automatic treatment button cannot be triggered), to prevent accidental restart of automatic treatment before the radiotherapy system has fully returned to normal or the problem has been resolved, thus avoiding unnecessary risks to the patient, such as inaccurate dosage or incorrect irradiation position.

[0155] In some embodiments, the control device 601 further includes a ready button (e.g., an MV ON light). When the MV ON light is illuminated, it indicates that the control device 601 is in a ready state. In response to a user's triggering operation on the MV ON light (e.g., pressing the MV ON light), the control device 601 controls the radiation source in the radiotherapy device 602 to emit a radiation beam towards the target area of ​​the target object.

[0156] In some embodiments, the control device 601 provides a terminate treatment button and a pause treatment button. A user can trigger the terminate treatment button to provide a termination treatment command to the control device 601; or, a user can trigger the pause treatment button to provide a pause treatment command to the control device 601.

[0157] Optionally, the control device 601 can respond to a treatment termination command or a treatment pause command by controlling the radiation source to stop emitting radiation beams toward the target area of ​​the target object.

[0158] It should be noted that if continuing beam delivery is temporarily unsuitable (e.g., the patient has slightly shifted their position but can still adjust), the user can trigger the pause treatment button to interrupt beam delivery. Once the patient's position is adjusted, beam delivery can resume for subsequent treatment without completely restarting. If continuing beam delivery is unsuitable (e.g., more serious problems arise, such as severe patient discomfort or significant equipment malfunction), the user can trigger the stop treatment button to terminate beam delivery. These triggering operations and corresponding status changes ensure the safety, accuracy, and effectiveness of the radiotherapy process, ensuring that the patient receives treatment with minimal risk.

[0159] In some embodiments, the control device 601 further includes a host computer and multiple slave computers. The slave computers include a real-time communication (RTC) system and various treatment sub-modules. The treatment sub-modules include an imaging module, a treatment plan verification module, etc.

[0160] The host computer is used to send the target treatment plan to each slave computer. The host computer also sends control commands to each sub-module via the RTC module, enabling each sub-module to assist the radiotherapy device 602 in treating the target subject. After each treatment sub-module successfully parses the target treatment plan, it sends a signal to the RTC system to remove the interlock / lock state (NGR, OGR case not ready), allowing each sub-module to assist the radiotherapy device 602 in treating the target subject.

[0161] The following is a detailed introduction to the radiotherapy equipment 602.

[0162] In one possible implementation, the radiotherapy device 602 is specifically used to execute a targeted treatment plan in response to control commands from the control device 601, and to perform radiotherapy on the target object. For example, a continuously rotating gantry drives the radiation source to rotate around the target object, so that the radiation source emits a radiation beam toward the target area of ​​the target object to achieve the purpose of radiotherapy.

[0163] Optionally, the radiotherapy device 602 includes a linear accelerator and / or a gamma knife. Of course, the above is merely an exemplary description of the radiotherapy device 602, which may also include other devices, such as proton therapy devices, electronic therapy machines, cobalt-60 therapy machines, CyberKnife, etc., and this application does not impose any limitations in this regard.

[0164] Similarly, the sub-treatment plan in this application can be a treatment plan applied to a linear accelerator or a treatment plan applied to a Gamma Knife. Of course, the sub-treatment plan in this application can also be a treatment plan applied to a proton therapy device, or a treatment plan applied to Cobalt-60, or a treatment plan applied to an electronic therapy machine, or a treatment plan applied to CyberKnife. Of course, when the radiotherapy device 602 is another device, the sub-treatment plan in this application can also be a treatment plan applied to that other device; this application does not impose any restrictions on this.

[0165] Based on the above technical solution, the radiotherapy system provided in this application includes a radiotherapy planning device, a radiotherapy device, and a control device. The radiotherapy planning device is used to issue a target treatment plan; the radiotherapy device includes a continuously rotatable gantry and a radiation source mounted on the gantry, and the gantry can drive the radiation source to rotate around the target object. Furthermore, the control device can receive the target treatment plan generated by the treatment plan generation method provided in the embodiments of this application, and control the radiation source to emit a radiation beam towards the target area of ​​the target object based on the target treatment plan. Since the target treatment plan is obtained by cascading multiple sub-treatment plans, compared to the current problem of excessively long switching times caused by multiple switching between sub-treatment plans when executing multiple sub-treatment plans, this technical solution eliminates the need for switching between multiple sub-treatment plans; treatment can be completed by executing a single target treatment plan, greatly improving treatment efficiency.

[0166] Furthermore, since the target treatment plan is obtained by cascading multiple sub-treatment plans, when the aforementioned control equipment performs radiotherapy on the target subject based on the target treatment plan, it can provide different treatment plans (such as different treatment doses, treatment angles, etc.) for different parts of the target subject according to the nature of the lesions, so as to make the treatment more precise and optimize the treatment effect.

[0167] The following, combined with Figures 8-10 The method for generating treatment plans is described in detail.

[0168] Figure 8 A flowchart illustrating a radiotherapy method provided in this application embodiment. Figure 8 As shown, the method includes the following S801-S802.

[0169] S801, Receive the target treatment plan.

[0170] The target treatment plan is generated using the treatment plan generation method shown in the embodiments of this application.

[0171] In one possible implementation, the target treatment plan is a treatment plan resulting from the cascading processing of multiple sub-treatment plans. Specifically, a description of the target treatment plan is provided in the embodiment shown in S102, and will not be repeated here.

[0172] S802, Based on the target treatment plan, control the radiation source to emit radiation beams toward the target area of ​​the target object.

[0173] In some embodiments, the implementation process of S802 includes: repeatedly performing the following first operation until all cycles of the treatment plan in the target treatment plan have been executed.

[0174] In one example, consider a 3-circle treatment plan consisting of a single-circle treatment plan and a 2-circle treatment plan. The first operation is performed to achieve the first circle of the target treatment plan; then the first operation is performed again to achieve the second circle of the target treatment plan; and then the first operation is performed again to achieve the third circle of the target treatment plan.

[0175] In one possible implementation, the first operation includes: determining the identification information of the Mth cycle treatment plan in the target treatment plan; and executing the Mth cycle treatment plan based on the identification information of the Mth cycle treatment plan to control the radiation source to emit a radiation beam toward the target area of ​​the target object.

[0176] The identification information includes the execution order of the Mth cycle treatment plan within the target treatment plan; M is a positive integer.

[0177] Specifically, the specific implementation scheme of the first operation mentioned above is as shown in the embodiments in S901-S902, and will not be repeated here.

[0178] Optionally, in some embodiments, during the execution of S802, in response to a treatment termination command or treatment pause command, the radiation source is controlled to stop emitting radiation beams towards the target area of ​​the target object to ensure treatment safety. Alternatively, when a chaining / lockdown is detected in the radiotherapy system, the radiation source is automatically controlled to stop emitting radiation beams towards the target area of ​​the target object.

[0179] It is understandable that when a chain / lockdown is detected in the radiotherapy system, it means that the radiotherapy system has experienced an abnormality or malfunction, and the treatment is automatically interrupted (that is, the radiation source is automatically controlled to stop emitting radiation beams to the target area of ​​the object), which can ensure the safety and accuracy of the treatment.

[0180] Based on the above technical solution, the radiotherapy method provided in this application receives a target treatment plan generated by the treatment plan generation method provided in the embodiments of this application, and controls a radiation source to emit a radiation beam toward the target area of ​​the target object based on the target treatment plan. Since the target treatment plan is obtained by concatenating multiple sub-treatment plans, compared to the current problem of excessively long switching times caused by multiple switching between sub-treatment plans when executing multiple sub-treatment plans, this technical solution eliminates the need for switching between multiple sub-treatment plans; treatment can be completed by executing a single target treatment plan, greatly improving treatment efficiency.

[0181] Furthermore, because the aforementioned radiotherapy methods utilize a target treatment plan, which is derived by cascading multiple sub-treatment plans, when performing radiotherapy on a target subject based on the target treatment plan, different treatment plans (such as different treatment doses and angles) can be provided for different sites according to the nature of the lesions, making the treatment more precise and optimizing the treatment effect.

[0182] As one possible embodiment of this application, combined with Figure 8 ,like Figure 9 As shown, the above S802 can be specifically implemented through the following S901-S902.

[0183] S901. Determine the identification information of the Mth cycle treatment plan in the target treatment plan.

[0184] In one example, consider a 4-circle treatment plan consisting of a single-circle treatment plan and a 3-circle treatment plan, where the Mth circle is the 3rd circle in the target treatment plan. The identification information for the 3rd circle treatment plan includes the execution order of the 3rd circle treatment plan.

[0185] Optionally, the identification information of the third round of treatment plan may also include the round number identifier of the second round in the three-round treatment plan and the treatment plan identifier of the three-round treatment plan.

[0186] S902. Based on the identification information of the treatment plan of the Mth cycle, execute the treatment plan of the Mth cycle to control the radiation source to emit radiation beams toward the target area of ​​the target object.

[0187] In one example, based on the identification information of the third treatment plan, the treatment data corresponding to the second round in the three-round treatment plan is located and retrieved from the database; the treatment data corresponding to the third treatment plan (that is, the second round treatment plan in the three-round treatment plan) is executed to control the radiation source to emit a radiation beam toward the target area of ​​the target object.

[0188] If the third treatment cycle is for a Gamma Knife procedure, the treatment data includes the radiation dose of the radiation beam, gantry rotation speed, gantry angle, blade position, arc start point, and arc end point during that cycle. If the third treatment cycle is for a linear accelerator procedure, the data includes the blade position, gantry angle, and gantry rotation speed during the execution of the sub-treatment plan.

[0189] The above technical solution determines the identification information of the Mth treatment plan in the target treatment plan, and executes the Mth treatment plan corresponding to the execution information of the Mth treatment plan based on the identification information of the Mth treatment plan, thereby controlling the radiation source to emit a radiation beam towards the target area of ​​the target object. In the embodiments of this application, the above scheme can be repeatedly executed multiple times to achieve the target treatment plan.

[0190] As one possible embodiment of this application, such as Figure 10 As shown, radiotherapy methods may include the following S1001-S1003.

[0191] S1001, Receive the target treatment plan, including the image-guided protocol.

[0192] The target treatment plan, including the image-guided approach, is generated using the treatment plan generation method shown in S301-S302 of this application embodiment.

[0193] Specifically, the description of the target treatment plan, including the image-guided approach, is provided in the embodiment shown in S302, and will not be repeated here.

[0194] S1002. Based on the target treatment plan including the image-guided scheme and user selection, after executing the image-guided scheme, execute each sub-treatment plan in the target treatment plan, and control the radiation source to emit radiation beams toward the target area of ​​the target object.

[0195] In one possible implementation, the implementation process of S1002 includes: based on the user's operation instruction, if the operation instruction indicates that the image guidance plan should be executed first and the target treatment plan should be executed after the image guidance plan is executed, then the image guidance plan is executed and the target treatment plan is executed after the image guidance plan is executed, and the radiation source is controlled to emit a radiation beam toward the target area of ​​the target object.

[0196] Among them, the user's operation instructions are the operation commands selected and issued by the user.

[0197] Alternatively, in another possible implementation, the implementation process of S1002 includes: acquiring image guidance information; in the case where the image guidance information indicates that an image guidance plan is executed first and a target treatment plan is executed after the image guidance plan is executed, in response to the image guidance information, executing the image guidance plan and executing the target treatment plan after the image guidance plan is executed, and controlling the radiation source to emit a radiation beam toward the target area of ​​the target object.

[0198] The image guidance information is a decision-making guidance scheme that predefines whether to execute the image guidance plan based on user selection. In other words, this application does not limit the specific form of user selection; it can be an operation instruction issued based on user selection, or it can be image guidance information pre-generated based on user selection.

[0199] In one example, an image-guided protocol is executed to locate the target area of ​​the subject, thereby facilitating accurate irradiation of the target area by the radiation beam. After executing the image-guided protocol, a targeted treatment plan is executed to control the radiation source to deliver the radiation beam to the target area of ​​the subject.

[0200] S1003. Based on the target treatment plan including the image-guided protocol and user selection, the target treatment plan is executed directly without executing the image-guided protocol, and the radiation source is controlled to emit a radiation beam toward the target area of ​​the target object.

[0201] In one possible implementation, the implementation process of S1003 includes: based on the user's operation command, if the operation command indicates that the image guidance plan should not be executed and the target treatment plan should be executed directly, then the execution steps of the image guidance plan are skipped and the target treatment plan is executed directly, and the radiation source is controlled to emit a radiation beam toward the target area of ​​the target object.

[0202] Alternatively, in another possible implementation, the implementation process of S1003 includes: acquiring image guidance information; if the image guidance information indicates that the target treatment plan is executed directly without executing the image guidance scheme, in response to the image guidance information, skipping the execution steps of the image guidance scheme, directly executing the target treatment plan, and controlling the radiation source to emit a radiation beam toward the target area of ​​the target object.

[0203] The process of controlling the radiation source to emit a radiation beam toward the target area of ​​the target object in order to implement the target treatment plan is described in the embodiment shown in S802 above, and will not be repeated here.

[0204] It should be noted that S1002 and S1003 are implemented based on user selection. That is, based on user selection, either S1002 or S1003 can be executed.

[0205] Based on the above technical solutions, when the treatment plan is a target treatment plan that includes an image-guided approach, the implementation scheme of the treatment plan can be flexibly switched based on the user's selection. For example, based on the user's selection, a scheme can be implemented where the target treatment plan is executed after the image-guided approach, and the radiation source is controlled to emit a radiation beam towards the target area of ​​the target object; or a scheme can be implemented where the target treatment plan is executed directly without executing the image-guided approach, and the radiation source is controlled to emit a radiation beam towards the target area of ​​the target object.

[0206] This application embodiment can divide the radiotherapy device into functional modules or functional units according to the above method examples. For example, each function can be divided into a separate functional module or functional unit, or two or more functions can be integrated into one processing module. The integrated module can be implemented in hardware or in software functional modules or functional units. The module or unit division in this application embodiment is illustrative and only represents one logical functional division; other division methods may be used in actual implementation.

[0207] The following, combined with Figure 11 This section provides a detailed introduction to radiotherapy equipment.

[0208] like Figure 11 The diagram shown is a structural schematic of a radiotherapy device 110 provided in an embodiment of this application. The radiotherapy device 110 includes a communication unit 1101 and a processing unit 1102.

[0209] The communication unit 1101 is used to receive the target treatment plan; the processing unit 1102 is used to control the radiation source to emit a radiation beam toward the target area of ​​the target object based on the target treatment plan.

[0210] In one possible implementation, the processing unit 1102 is specifically used to: determine the execution information of the Mth round treatment plan in the target treatment plan; the execution information carries the target round number M of the Mth round treatment plan and the identification information corresponding to the Mth round treatment plan; M is a positive integer; based on the execution information of the Mth round treatment plan, execute the Mth round treatment plan corresponding to the execution information of the Mth round treatment plan, and control the radiation source to emit a radiation beam towards the target area of ​​the target object.

[0211] In one possible implementation, the communication unit 1101 is further configured to receive a target treatment plan including an image-guided scheme; the processing unit 1102 is further configured to, based on the target treatment plan including the image-guided scheme, execute the target treatment plan after the user selects to execute the image-guided scheme, control the radiation source to emit a radiation beam toward the target area of ​​the target object, or, without executing the image-guided scheme, directly execute the target treatment plan and control the radiation source to emit a radiation beam toward the target area of ​​the target object.

[0212] In one possible implementation, the radiotherapy device 110 may further include a storage unit 1103. Figure 11 (shown in dashed box) The storage unit 1103 stores a program or instruction, which, when executed by the processing unit 1102, enables the radiotherapy apparatus 110 to perform the radiotherapy method described in the above method embodiment.

[0213] When implemented in hardware, this application also provides an electronic device for executing the treatment plan generation method shown in the above method embodiments, and / or, a radiotherapy method.

[0219] In one possible design, the memory 1203 can exist independently of the processor 1201, meaning the memory 1203 can be an external memory of the processor 1201. In this case, the memory 1203 can be connected to the processor 1201 via a communication line 1202 to store execution instructions or application code, and its execution is controlled by the processor 1201 to implement the treatment plan generation method and / or radiotherapy method provided in the following embodiments of this application. In another possible design, the memory 1203 can also be integrated with the processor 1201, meaning the memory 1203 can be an internal memory of the processor 1201. For example, the memory 1203 can be a cache, which can be used to temporarily store some data and instruction information.

[0220] As one possible implementation, processor 1201 may include one or more CPUs, for example Figure 12 CPU0 and CPU1 in the example. As another possible implementation, the electronic device may include multiple processors, such as... Figure 12 The processors 1201 and 1207 are included.
