Embodiment 1

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

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

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

[0052] In step 102, the review of the outline according to the structural information includes: according to the structural information, using dilation and erosion algorithms to calculate the connectivity of the outline, determining the position of the missing layer in the structural information, and giving a reminder of the missing layer ; According to the structural information, use the expansion and erosion algorithm to determine the volume of the connected domain in the structural information, determine the connected domain with a volume less t...

Embodiment 2

[0062] The present invention also provides an automated quality control system for radiotherapy procedures, the system includes a physicist's second-level automatic audit module and a physicist's third-level automatic audit module; the physicist's second-level automatic audit module is used to extract Structural information in CT images with outlines; the outlines include: patient outlines, treatment target outlines, and organ-at-risk outlines; outlines are reviewed based on the structural information; prescriptions are planned according to doctor applications and physicists execute plans , to perform plan review; the physicist's three-level automatic review module is used to perform safety review according to the CT image, the doctor's application plan prescription and the physicist's execution plan.

Embodiment 3

[0064] An automated platform for quality control of radiotherapy procedures, 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 The patient terminal is used to make an appointment for patient treatment; the physicist terminal is used to enter the physicist's execution plan; the equipment monitoring terminal is used to track the status of the treatment equipment; the charging terminal is used to collect treatment fees; the background center is used for It is used for automatic quality control of radiation therapy process, automatic appointment of treatment equipment, automatic evaluation of doctor's application plan prescription, information recording and feedback.

[0065] The doctor terminal includes: a simulated positioning information input module and a doctor tr...

Abstract

The invention relates to an automatic quality control method, system and platform for a radiotherapy process. The method comprises the following steps: extracting structural information in a CT image with a delineated contour, wherein the delineated contour comprises a patient contour, a treatment target region contour and an endangered organ contour; checking the delineated contour according to the structure information; checking the plan according to the doctor application plan prescription and the physicist execution plan; and according to the CT image, the doctor application plan prescription and the physicist execution plan, performing security auditing. According to the method, CT image delineating, doctor application plan prescription and physicist execution plan automatic auditing are realized, the method is applied to a radiotherapy process quality control automatic platform, automatic quality control in the whole radiotherapy process is realized, paperless process is realized, and errors and accidents in the radiotherapy process 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 radiation therapy is to give sufficient dose to the tumor target area under the premise of protecting the organs at risk as much as possible so as to achieve the purpose of controlling or even killing the tumor. In order to achieve the above goals, it is necessary to formulate an accurate 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, and the irradiation technology is also moving towards the direction of precision, automation and informationization. However, the existing quality control management of the whole process of radiotherapy i...
