Abstract

The invention relates to a rapid and accurate tumour position prediction apparatus. The apparatus includes a data set acquisition and preprocessing module, a sample training set generation module, and a data learning and prediction module, obtains the respiratory movement data and tumour position historical data through the data set acquisition and preprocessing module, and generates the tumour position prediction functions through the sample training set generation module and the data learning and prediction module, thus rapidly and accurately predicting the newly acquired tumour position information of patients by using the tumour position prediction functions. The apparatus improves the accuracy of the real-time tracking and positioning in the tumour target of a patient during the accurate radiation treatment, and corrects the patient's position during the treatment, thereby maximally reducing the error influence caused by target and organ motion.

Description

technical field [0001] The invention relates to the positioning and tracking of a patient's tumor target area in radiotherapy, specifically refers to the prediction of the tumor position in the process of precise radiotherapy, and relates to a fast and accurate tumor position prediction device. Background technique [0002] With the development of radiotherapy technology, tumor radiotherapy has entered the stage of "precise positioning, precise planning, precise implementation, and precise verification". Precision radiotherapy technology enables the modernization of high precision, high dose, high efficacy and low damage in tumor treatment The radiotherapy model is gradually becoming a reality. However, the accuracy of clinical radiotherapy is often affected by the breathing movement of the human body, resulting in varying degrees of movement or even dislocation of the tumor target area, which seriously affects the treatment effect. In order to be able to reduce the impact ...
