Radiotherapy plan optimization method and device, and storage medium

The invention provides a radiotherapy plan optimization method and device and a storage medium, and relates to the technical field of medical treatment. According to the specific implementation scheme, the method comprises the steps of adjusting a target spot position in an initial radiotherapy plan based on a deviation between a fractional radiotherapy image of an object to be subjected to radiotherapy and an initial radiotherapy image corresponding to the initial radiotherapy plan of the object to be subjected to radiotherapy; determining the dose distribution of the target area of the object to be subjected to radiotherapy based on the adjusted target spot position; optimizing a target weight based on the dose distribution to obtain an optimized target weight; and generating an optimized radiotherapy plan based on the optimized target weight. In this way, the initial radiotherapy plan is adaptively adjusted, so that the quality of the radiotherapy plan is improved. 本公开提供了一种放疗计划的优化方法、设备以及存储介质，涉及医疗技术领域。具体实现方
