Embodiment 1

[0049] The present invention provides an automatic quality control method for radiotherapy process, such as figure 1 As shown, the method includes the following steps:

[0050] Step 101 , extracting the structural information in the CT image with outlines; the outlines include: patient outline, treatment target area outline and organ at risk outline.

[0051] Step 102 , review the outline according to the structure information.

[0052] Step 102, according to the structure information, the review of the outline, specifically includes: according to the structure information, using the expansion and corrosion algorithm to calculate the connectivity of the outline, determine the position of the missing layer in the structural information, and give the missing layer prompt ; According to the structural information, the volume of the connected domain in the structural information is determined by the expansion and erosion algorithm, the connected domain with the volume less than 0...

Embodiment 2

[0062] The present invention also provides an automatic quality control system for radiotherapy process, the system includes a physicist second-level automatic review module and a physicist third-level automatic review module; the physicist second-level automatic review module is used for extracting bandages. Structural information in CT images with contoured contours; the contoured contours include: patient contours, treatment target contours, and organ-at-risk contours; review the contoured contours based on the structural information; plan prescriptions according to doctors’ application and physicist execution plans , to review the plan; the physicist three-level automatic review module is used to review the safety according to the CT image, the doctor's application for the plan prescription and the physicist's execution plan.

Embodiment 3

[0064] An automated platform for radiotherapy process quality control, the platform includes: a doctor terminal, a patient terminal, a physicist terminal, an equipment monitoring terminal, a charging terminal and a background center; the doctor terminal is used for inputting patient medical order information and doctor treatment plans.

Abstract

The present invention relates to an automated quality control method, system and platform for radiotherapy procedures. The method includes the following steps: extracting structural information in a CT image with contoured contours; the contoured contours include: patient contour, treatment The contour of the target area and the contour of the organ at risk; review the outline according to the structural information; review the plan according to the doctor's application for the plan prescription and the physicist's execution plan; according to the CT image, the doctor's application for the plan prescription and the physicist Execute plan for security audit. The invention realizes the automatic review of delineating CT images, doctor's application for plan prescription and physicist's execution plan, and applies it to the radiotherapy process quality control automation platform to realize automatic quality control in the whole radiotherapy process and realize paperless process At the same time, errors and accidents during radiotherapy are reduced.

Description

technical field [0001] The invention relates to the technical field of treatment process monitoring, in particular to an automatic quality control method, system and platform for radiotherapy process. Background technique [0002] The purpose of radiotherapy is to give sufficient dose to the tumor target area to control or even kill the tumor under the premise of protecting the organs at risk as much as possible. In order to achieve the above goals, it is necessary to formulate a precise treatment plan, and the premise of an accurate plan is the safety of the treatment process. With the development of radiotherapy in recent years, the original two-dimensional radiotherapy has entered the current stage of image-guided radiotherapy. At the same time, the irradiation technology is also moving towards the direction of precision, automation and informatization. However, the existing quality control management of the whole process of radiotherapy is still an important aspect that...
