Radiotherapy dose early warning method, equipment, medium and product

Abstract

The invention provides a radiotherapy dose early warning method. The radiotherapy dose early warning method comprises the steps of receiving target radiotherapy plan data corresponding to a target patient and target CBCT data of the target patient during each radiotherapy; according to target reflex therapy plan data and the target CBCT data, calculating a target density variable of the CBCT data during each radiotherapy of the target patient; outputting each target density variable to a preset dose feature solving model to obtain a corresponding target radioactive source dose feature; and judging whether the dose characteristic of the target radioactive source is within a clinical dose characteristic standard range, and if not, sending out early warning information. According to the radiotherapy dose early warning method, complex calculation of dose characteristics of the target radioactive source is not needed, the early-stage calculation process of radiotherapy dose early warning is simplified, and the early warning efficiency is improved.

Description

technical field [0001] The invention relates to the field of tumor radiotherapy, in particular to a radiotherapy dose early warning method, equipment, medium and method. Background technique [0002] With the update of medical equipment and the advancement of diagnosis and treatment technology, external beam radiation therapy based on linear accelerators has become an irreplaceable key link in comprehensive tumor therapy. With the application of three-dimensional conformal, intensity-modulated radiation therapy (IMRT), and volumetric modulated arc therapy (VMAT), a highly conformal dose can be obtained for tumors and their associated targets. Surrounding. And the dose in the target area can be adjusted according to clinical requirements, and a differentiated dose gradient can be formed between the periphery of the target area and the organs at risk, which maximizes the killing of tumors and better protects normal tissues. There are inevitably certain uncertainties in radiot...

Problems solved by technology

[0007] The second object of the present invention is to provide an electronic device, which can solve the problem of reconfirmation of the target area - redesign of the plan - reassessment of the plan in the existing operation process of using DGRT technology to warn the dose of radiation therapy -The whole-process operation of the planned re-validation does not take into account the inherent characteristic relationship between the density change and the dose characteristics, which leads to the problem that the entire early warning process takes a long time and the early warning efficiency is not high

[0008] The third object of the present invention is to provide a computer-readable storage medium, which can solve the problem of completing reconfirmation of the target area-plan redesign- Planned reassessment-the whole process of planned revalidation does not take into account the inherent characteristic relationship between the density change and the dose characteristics, which leads to the problem that the entire early warning process takes a long time and the early warning efficiency is not high
