Abstract

Disclosed are a method and a system for evaluating the effect of radiotherapy, relating to the technical field of medical software. The method comprises: receiving an input computed tomography CT image, structure contour information of a human organ and a tumour target area, a distribution matrix of a radiotherapy dosage and a radiotherapy planning radiation field parameter; obtaining the single physical dosage of each voxel point of the human organ and the tumour target area through identification; calculating the biological equivalent dosage of each voxel point of the human organ and the tumour target according to the single physical dosage of each voxel point of the human organ and the tumour target and the radiotherapy planning radiation field parameter; and evaluating the effect of radiotherapy according to the biological equivalent dosage and the single physical dosage. Obtaining the single physical dosage through identification, calculating the biological equivalent dosage and constructing a corresponding contour line solves the problem of inaccurate evaluation of the effect of radiotherapy which is present in the prior art.

Description

technical field [0001] The invention belongs to the technical field of medical software, in particular to a method and system for evaluating the effect of radiotherapy. Background technique [0002] In the field of tumor radiotherapy, after the radiologist arranges a radiotherapy plan based on radiation exposure for tumor patients, the radiotherapy physicist designs a radiotherapy plan that meets the requirements of the treatment plan through the Treatment Planning System (TPS). The radiotherapy plan output by the TPS includes the treatment field parameters (mainly including the motion parameters of each moving part of the accelerator when the accelerator that generates therapeutic radiation irradiates the tumor site with radiation therapy, such as radiation incident angle, field shape, and radiation energy. , number of hops, number of total points of irradiation, etc.), the three-dimensional dose distribution of the physical dose absorbed by the patient's body in the patien...
