A Method of Automatic Prediction of Planning Difficulty Based on DVH Forecasting Model

Abstract

The invention discloses a method for automatically predicting a plan difficulty degree based on a DVH predicting model. The method comprises the following steps of (1), collecting sketching data and planning data of a cancer patient of the same kind, and training the DVH predicting model of an in-danger organ by means of collected data; (2), inputting the target area of a new case, and the sketching data of the in-danger organ, and by means of the trained DVH predicting model, predicting the DVH curve of each in-danger organ; and (3), by means of the predicted DVH curve of the in-danger organ,evaluating the difficulty degree of the plan. The method can effectively realize an automatic process for predicting the difficulty degree of the plan, thereby realizing automatic radiotherapy plan distribution, and improving accuracy and efficiency in predicting the difficulty degree of the plan.

Description

technical field [0001] The invention belongs to the field of radiotherapy, and in particular relates to a method for automatically predicting the degree of difficulty of planning based on a DVH prediction model. Background technique [0002] Radiation therapy (hereinafter referred to as "radiotherapy") plan design is an important part of the radiation therapy process. Physicists with different experiences spend different time in designing radiotherapy plans and the quality of the designed plans is also different. In actual work, in order to improve the overall For the efficiency and quality of the radiotherapy process, the hospital will assign plans of different difficulty to physicists with different experiences to design, so a question naturally arises: how to predict the difficulty of the plan? [0003] In the previous radiotherapy process, the prediction of the difficulty of the plan was implemented by the physicist based on his own experience. This traditional method ha...
