Detailed Description
The present application will be described in detail below with reference to the accompanying drawings in conjunction with embodiments. It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict.
Aiming at the problems that the patient plan data can only be verified on site, so that the verification form is single, the timeliness is poor and the personalized requirements of users cannot be met, the embodiment of the application provides a method for verifying the patient plan data, as shown in fig. 1, the method comprises the following steps:
101. a radiotherapy plan file for a target patient is acquired.
In a specific application scenario, the radiotherapy plan file at least comprises a DCM file, an RS file, an RP file and an RD file corresponding to the positioning image, wherein the DCM file, the RS file, the RP file and the RD file are used for recording information such as the positioning image, the target region delineation region of the target patient, radiotherapy dose data corresponding to the radiotherapy plan and the like.
102. And uploading the radiotherapy plan file to a cloud TPS module.
In a specific application scenario, after a physicist finishes radiotherapy plan design, the plan data of a patient needs to be verified on a TPS, and a traditional verification mode only allows the physicist to confirm operation on the site on the TPS of a radiotherapy department.
103. And extracting verification parameters corresponding to the radiotherapy plan file in the cloud TPS module based on the preset access authority.
For this embodiment, in a specific application scenario, since the cloud TPS module establishes connections with the TPS of multiple radiotherapy departments at the same time, in order to ensure security of data access, access permissions should be configured for each access terminal. And in specific access, only checking and extracting verification parameters corresponding to the preset access authority in the cloud TPS module.
104. And verifying the verification parameters by using a preset dose curve to obtain a data verification result.
Wherein, the tolerance dose of each organ corresponding to different focus volumes is set in the preset metering curve according to the national standard so as to be used as the check reference standard in the check process.
By the patient plan data verification method in the embodiment, the radiotherapy plan file of the target patient can be obtained firstly, and then the radiotherapy plan file is uploaded to the cloud TPS module, so that cloud storage of data is realized. The specific auditing process can be as follows: and extracting each verification parameter in the radiotherapy plan, and verifying the extracted verification parameters by using a preset dose curve to further obtain a data verification result. In this application, set up TPS in the high in the clouds to be convenient for carry out regional conjuncted collaborative quality control and management of doctor, can directly look over and verify radiotherapy data through the browser, need not confine to the mode of on-the-spot affirmation, when richening the data verification form, also can guarantee the promptness of radiotherapy plan verification, improve verification efficiency.
Further, as a refinement and an extension of the embodiments of the above embodiments, in order to fully illustrate the implementation process in the present embodiment, another method for checking patient planning data is provided, as shown in fig. 2, the method includes:
201. a radiotherapy plan file for a target patient is acquired.
For the embodiment, in a specific application scenario, because the radiotherapy plan of the target patient is often stored in the TPS of the radiotherapy department of the institution, when the radiotherapy plan is stored in the TPS of the radiotherapy department, a physicist is only allowed to perform confirmation operation on site in the TPS of the radiotherapy department, and due to the limitation of a site, the verification form is single, the timeliness is poor, and the personalized requirements of the user cannot be met. Therefore, in order to enhance the verification efficiency of the radiotherapy plan, radiotherapy plan files need to be extracted from the TPS of each radiotherapy department in advance, so that data connection between the TPS of the radiotherapy department and the cloud TPS module is established, and the radiotherapy plan files are uploaded to the cloud TPS module to be stored.
202. And uploading the radiotherapy plan file to a cloud TPS module.
In a specific application scenario, two ways can be adopted to upload a radiotherapy plan file to a cloud TPS module, wherein the first way can be: copying a patient image file in a TPS (focal plane temperature) of a radiotherapy department by using a preset storage tool, and copying and uploading the patient image file to a cloud TPS module; the second way may be: and sending the patient image file to a cloud TPS module based on an RT gateway technology. The preset storage device can be an external storage such as a floppy disk, a hard disk, an optical disk, a U disk, a mobile hard disk and the like.
203. And sending a data acquisition request about the verification parameters to the cloud TPS module, wherein the data acquisition request carries a user identifier, so that the cloud TPS module determines the data access authority based on the user identifier and returns the verification parameters matched with the data access authority.
For this embodiment, in a specific application scenario, since the cloud TPS module stores data in TPS of each radiotherapy department, in order to ensure security of data access, it is necessary to configure corresponding data access permissions for relevant staff in advance, and only allow each user to access radiotherapy data under the corresponding data access permissions. Specifically, a data acquisition request about the verification parameters can be sent to the cloud TPS module, where the data acquisition request carries a user identifier, and after receiving the data acquisition request, the cloud TPS module determines the corresponding matched data access right according to the user identifier and returns the verification parameters corresponding to the data in the data access right.
For example, after a user a sends a data acquisition request about a verification parameter to a cloud TPS module, the cloud TPS module may first verify an access right of the user a, and when it is determined that the user a does not have the data access right, the data acquisition request is not responded; when the user a is judged to have the data access right, the corresponding matched data access right is further determined according to the user identification corresponding to the user a, then the data A under the data access right is extracted, data processing is carried out on the data A, and the verification parameters about the data A are obtained and output to the user a.
204. The lesion area and normal tissue are determined based on the target delineated area.
For the embodiment, when the physicist or doctor obtains the verification parameters about the access data output by the cloud TPS module, the physicist or doctor further verifies the verification parameters to determine whether the current verification parameters meet the actual radiotherapy standards. First, the target area of an organ is sketched according to sketching coordinates and regional coordinates in a result, a focus region needing radiotherapy in the organ is determined, and normal tissues needing no radiotherapy or avoiding radiotherapy are not needed.
205. And calculating a target volume corresponding to the lesion area.
Correspondingly, when the organ corresponds to different lesion volumes, the corresponding tolerance dose is relatively changed, and the different lesion volumes correspond to different tolerance doses. For example, for a tissue organ such as the "lung", the corresponding tolerated dose may be 2000cGy when the lesion volume is 20%, and 100cGy when the lesion volume is 100%. Therefore, after the lesion area needing radiotherapy in the organ is determined according to the delineation coordinates and the area coordinates in the delineation result of the target area of the organ, the target volume corresponding to the lesion area needs to be further calculated, so as to verify the dose number of the radiotherapy plan in the target volume.
206. And extracting a first preset dose corresponding to a focus region under the target volume and a second preset dose corresponding to normal tissues from the preset dose curve.
The preset measuring curve can include DVH, equal dose curve, field distribution and the like, and is set with tolerance dose corresponding to different focus volumes of each organ so as to serve as a verification reference standard in a verification process according to national standards. The first preset dose is the minimum dose value corresponding to the focus region under the target volume. In order to ensure effective treatment of the focus area, the dose of the radiotherapy plan for the focus area is more than or equal to a first preset dose; the second preset dose is the maximum tolerated dose value corresponding to normal tissue, and in order to ensure that normal tissue is not affected, the dose of the radiotherapy plan for normal tissue should be less than or equal to the second preset dose.
In this embodiment, after the target volume corresponding to the lesion area is calculated, a first preset dose corresponding to the lesion area in the target volume and a maximum tolerance dose of other normal organs included in the patient image, that is, a second preset dose, may be further obtained in the preset dose curve.
207. The verification parameters are verified based on the first preset dose and the second preset dose.
For this embodiment, in a specific application scenario, the step 207 of the embodiment may specifically include: extracting a first dose corresponding to a focus region under a target volume and a second dose corresponding to a normal tissue from the verification parameters; if the first dose is determined to be less than the first preset dose and/or the second dose is determined to be greater than the second preset dose, determining that the patient planning data fails the verification; if the first dose is determined to be greater than or equal to the first preset dose and the second dose is determined to be less than or equal to the second preset dose, the patient planning data is determined to pass the verification.
Wherein the first dose is the number of doses set for a focal region in a radiotherapy plan; the second dose is the number of doses set for each normal tissue in the radiotherapy plan. In a specific application scenario, in order to ensure effective treatment of the lesion area and avoid invasion of other normal tissues, it should be ensured that the first dose is greater than or equal to the first preset dose and the second dose is less than or equal to the second preset dose.
208a, if the patient plan data is judged not to pass the verification, outputting first prompt information, wherein the first prompt information comprises verification parameters which do not pass the verification and reasons of the non-verification.
The first prompt information can comprise one or more of text prompt information, picture prompt information, audio prompt information, video prompt information, light prompt information, vibration prompt information and other prompt information and is used for prompting a physicist or a doctor that the formulated patient plan data fails to pass the verification; reasons for failing the verification may include: the dose number set for the lesion area is too small, or the dose number set for a specific normal tissue is too small.
In an example step 208b, which is parallel to the example step 208a, when it is determined that the patient plan data passes the verification, second presentation information indicating that the patient plan data passes the verification is output.
The second prompt information can comprise one or more of text prompt information, picture prompt information, audio prompt information, video prompt information, light prompt information, vibration prompt information and other prompt information and is used for prompting a physicist or doctor to verify the planned data of the patient. In a specific application scenario, in order to distinguish the first prompt message from the second prompt message, the second prompt message may be set to be different from the first prompt message.
By the patient plan data verification method, the radiotherapy plan file of the target patient can be obtained firstly, the radiotherapy plan file is uploaded to the cloud TPS module, cloud storage of data is achieved, and a physicist can verify the radiotherapy plan of the patient based on preset access authority in any place with a network through the cloud TPS module on line on the system.
