An end-to-end full-process quality control system for radiotherapy

Abstract

The present invention provides an end-to-end full-process quality control system for radiotherapy, relating to the technical field of equipment process quality control. The present invention achieves unification of spatial references by constructing a phantom three-dimensional spatial reference coordinate system unified with phantom positioning and mapping it to all devices throughout the entire process; by synchronously acquiring data from each stage under this reference and comparing it with theoretical values, an error accumulation model is used to analyze the error propagation chain, identifying and quantifying systematic errors introduced by device mapping mismatches; and further, based on the quantified results, coordinate remapping, parameter calibration, or logic adjustment instructions are dynamically generated and executed to perform closed-loop correction of errors. The present invention realizes full-chain automated quality control from error traceability to adaptive correction, effectively improving the overall accuracy and safety of the radiotherapy process.
