Description

Technical Field

[0001] The present invention relates to the technical field of quality control of a spiral tomographic radiotherapy system, and in particular to an integrated quality control management system and method for a spiral tomographic radiotherapy system. Background Art

[0002] The spiral tomography radiotherapy system is a set of relatively special radiotherapy technologies. The radiation is irradiated to the patient's tumor site through spiral tomography. During the treatment process, the radiation rotates around the central axis with the frame, and the treatment bed carries the patient to enter the treatment aperture synchronously at a certain speed. The treatment process requires the cooperation of multiple subsystems. If any subsystem does not cooperate properly, it will cause a large treatment error. Therefore, multiple quality control tests (Quality Assurance) are required to ensure the high-precision treatment of the spiral tomography radiotherapy system. Its quality control items are divided into daily inspection, monthly inspection and annual inspection according to the inspection cycle; according to the type of quality control, they are divided into equipment safety chain inspection, dose accuracy test, synchronization inspection of each system, position accuracy test and patient planned dose quality control test.

[0003] At present, all test items of the spiral tomography radiotherapy system are checked by the physicist in the radiotherapy department. The tools used are the software and hardware equipment of various systems and third parties. There is no unified system management, and the test results are recorded as paper documents. There is no unified report template, no trend comparison, no systematic result analysis, and no system warning. In clinical practice, physicists need to prepare multiple quality control tools for separate testing, separate recording, and manual analysis. The work is cumbersome, time-consuming and labor-intensive to execute, and records are easily lost. The quality control test of the spiral tomography radiotherapy system requires a unified system to manage and maintain the quality control process, quality control tools, and quality control results. At the same time, users in various regions or provinces and cities need to customize the generated report types and templates according to local regulations. Summary of the invention

[0004] The present invention aims to solve the deficiencies of the prior art and provide an integrated quality control management system and method for a spiral tomographic radiotherapy system.

[0074] S8. If the results of any quality control project exceed the threshold and trigger an early warning message, the user can manually authorize the triggering of the spiral tomography system manufacturer support and support uploading of fault pictures or files required for service support. Specific embodiment:

[0076] The quality control management system of the spiral tomography system can set different permissions for different physicists in the radiotherapy department, use the quality control calendar to establish daily, monthly and annual inspection items, and call the corresponding software and hardware to perform quality control tests and record and view them. The quality control system can call the analysis software in the software library to analyze the test results and automatically record them. If a quality control test result exceeds the threshold range, the system will give an early warning. If it cannot be handled, it can be repaired by the manufacturer through the system. The system is further explained in conjunction with specific embodiments.

[0077] P1. When the system is installed and configured for the first time, the relevant quality control items of the spiral tomotherapy system are predefined according to industry standards and relevant specifications, such as AAPM TG 148 and NCCT-RT003-2019, including safety interlocking, dose accuracy detection, machine mechanical accuracy detection, and linkage accuracy detection of each subsystem. At the same time, the system predefines the acceptable threshold range of each quality control item according to the requirements or recommendations of the specifications.

[0078] P2. When configuring the user terminal, the system will configure the site information according to the unique serial number of the equipment, and support a single site with multiple spiral tomography systems each with their own unique serial number. After the user enters the quality control management, selects the corresponding equipment unique serial number, and the system loads the associated quality control content.

[0079] P3. The quality control calendar displays the relevant quality control status of each day in a monthly format by default, including the content of all defined quality control plans distributed on each day. The user selects the start date in the quality control calendar to create a quality control plan for a specific time period, and then selects the quality control frequency (daily, weekly, monthly, quarterly or annual inspection), repetition rules (daily, weekly, monthly, quarterly or annually, you can customize working days or specific rules such as the first Saturday of each month, etc.), the system associates the relevant calendar dates according to the definition of the quality control plan and automatically creates the corresponding plan.

[0080] like Figure 4As shown, daily inspection includes routine function inspection, dose output stability inspection, red laser position verification, and imaging system accuracy verification; weekly inspection includes secondary collimator accuracy inspection and CT number inspection; monthly inspection includes dose verification, red laser movement accuracy verification, interruption dose verification, beam parameter inspection, treatment bed accuracy verification, and image quality inspection; quarterly inspection includes synchronization test and image dose inspection; annual inspection includes primary collimator accuracy verification, red / green laser positioning and movement accuracy verification, secondary collimator accuracy verification, all beam parameter inspection, multi-dimensional image quality inspection, and annual dose verification.

[0081] P4. After the relevant content of the quality control plan is selected, the system automatically matches all applicable quality control test items based on the selected information. These quality control items are derived from industry specifications and standards. Users add, delete and confirm the items to be executed based on the actual requirements of the province, city or region. After confirmation, the quality control calendar displays the quality control status of all applicable dates in the plan with different icons according to the project detection situation. The quality control calendar is synchronized to the date associated with each quality control plan, and the quality control plan with the current status of not being executed is displayed in the form of a hollow circle on a single date in the quality control calendar.

[0082] P5. Select the quality control plan that has not been executed on that day to enter the stage of entering quality control results. The system lists the quality control items selected in the plan one by one according to the set quality control order, and leaves the result column blank. Users can enter the quality control test results into the system manually or automatically.

[0083] The results of manual entry include: a. Select pass or fail; b. Fill in the value. There are two main ways to automatically enter: a. Analyze the machine startup and preheating log files to parse out the relevant results, and match the corresponding quality control project input box to enter the results (pass or fail); b. Through RPA (Robotic Processing Automation), the user calls the relevant software to analyze the results, and after the results are generated, the RPA saving mechanism is triggered and the corresponding quality control project result column is automatically entered. The results also include two ways of manual entry. It also supports uploading result attachments.

[0084] P6. After saving the input results, the background of the result system will automatically select the failed quality control project results and enter the early warning information. For other projects with threshold judgments, the background algorithm will judge whether they have passed, failed, or passed with warning information based on the comparison of the preset quality control test project results with the threshold range. The system displays the pass status of the quality control items tested on that day with different icons on each independent date of the corresponding calendar of the quality control dashboard. Among them, the pass is displayed with a green dot, the fail is displayed with a red dot, and the pass with warning is displayed with an orange dot, such as Figure 3 shown.

[0085] Users can click on these dots to open the quality control details, which show all the quality control items in the quality control plan for that day. When you open a certain item, you can see the details of the item, including the project introduction, recommended thresholds, actual results, and related drawings. If you do not need to generate a report or report a repair, saving the results will complete the routine quality control implementation.

[0086] P7. If you have completed a quality control or a quality control plan for a period of time and need to create a report, enter the quality control report stage, select the report-related elements, report type, start and end dates according to the predefined report template, and generate the corresponding quality control report. Users can also customize the report template according to their own needs. The report type can be a single quality control report or a trend report for a period of time. The exported report can be saved as a pdf document and supports electronic signatures.

[0087] P8. If the test results of the quality control items exceed the threshold, an early warning message will be triggered. The user can use the one-click repair function integrated in the system to open the network connection and trigger the spiral tomography system manufacturer support application, and upload the pictures or file information related to the repair request required by the service support.

[0088] The present invention can integrate multiple quality control tools and software and hardware required for the quality control test of the spiral tomography system, and unify the management of the quality control process of the entire spiral tomography system, including software and hardware calling, automatic / manual result entry, quality control result analysis, automatic early warning, report creation and other functions, filling the gap in the unified management system for quality control testing of spiral tomography systems, establishing an electronic system for quality control data, and integrating an intelligent data processing system, thereby improving the work efficiency of front-line radiation therapy physicists.
