Patent ID: 10646725

Abstract:
Provided in the present invention is a three-dimensional precise intracavitary radiotherapy method and system for treating tumours, comprising the steps of: (1) lesion three-dimensional quantitative measurement and analysis of three-dimensional scanning image of the lesion cavity; (2) comprehensive analysis according to lesion three-dimensional quantitative measurement results and lesion characteristics to calculate the three-dimensional distribution of lesion radiation dose; and (3) according to the three-dimensional distribution diagram of radiation dose, selecting appropriate radiation sources and radiation dose to make a stent, and performing three-dimensional precise intracavitary radiotherapy. At the same time, also provided by the present invention is a system for achieving the above radiotherapy method. The present invention uses modern medical imaging three-dimensional reconstruction technology for realizing three-dimensional precise internal radiotherapy to treat tumours with an optimized radiation dose and protect normal tissues to an extreme.
