Abstract

The embodiment of the invention discloses a radiotherapy plan generation system and device and a storage medium. The system comprises a memory, a processor and a computer program which is stored on the memory and can run on the processor. When the processor executes the program, the following steps are implemented: determining a plurality of current constraint points according to a pre-plan imageand a radiotherapy prescription; if each current constraint point does not meet a first preset convergence condition, determining a current candidate constraint point corresponding to the target constraint point from the current constraint points, and completing movement of each current constraint point based on the current candidate constraint point so as to iteratively update each current constraint point until each updated current constraint point meets the first preset convergence condition; and taking the updated current candidate constraint point as a target constraint point, and generating a target radiotherapy plan according to the target constraint point. Through the technical scheme, the optimization efficiency of the radiotherapy plan is improved.

Description

technical field [0001] Embodiments of the present invention relate to medical technology, and in particular to a radiotherapy plan generating system, device and storage medium. Background technique [0002] In the radiotherapy (referred to as radiotherapy) system, the physicist needs to generate an executable radiotherapy plan through the radiotherapy planning system according to the radiotherapy prescription issued by the doctor, such as the required dose of the tumor target area and the tolerance dose of organs at risk, such as radiotherapy wild shape and hop count etc. [0003] In the current radiotherapy planning system software, there is a complete optimization workflow. The physicist needs to determine the reasonable constraints for generating a radiotherapy plan according to the radiotherapy prescription, and then input it into the radiotherapy planning system software to generate a radiotherapy plan. In the process of radiotherapy plan optimization, the constraints ...
