Problems solved by technology

[0003] However, the inventors found that during the course of tumor treatment, even in a short observation time, as the volume of the tumor cell population changes and the position moves slightly, the target of tumor treatment will move and transform to the periphery of its original position, This in turn leads to deviations in radiation angles and inaccurate radiation doses, making dynamic tumor radiation techniques unable to achieve ideal th

Abstract

The invention provides a method for dynamically adjusting the radioactive angle and dosage according to the movement of a tumor. According to the method, the moving position and spreading area of a dynamic tumor are precisely predicted and tracked, and the deflection of a radioactive angle is adjusted in time, and the radioactive dosage of a treatment target can be accurately controlled. The method comprises the following steps: (1) extracting the edge of a target tumor; (2) performing area related matching; (3) performing time grid clustering; (4) predicting the moving tumor position; and (5)adjusting the radioactive angle and dosage.

Description

technical field [0001] The invention relates to the technical field of dynamic tumor radiation, in particular to a method for dynamically adjusting radiation angle and dose according to tumor movement. Background technique [0002] With the development of radiotherapy technology, more and more attention has been paid to precise radiotherapy technology. Dynamic Tumor Adjustment Radiation technology can more accurately and efficiently adjust the radiation angle and prescribed dose of radiation compared with other solutions to the problem of tumor movement caused by breathing. [0003] However, the inventors found that during the course of tumor treatment, even in a short observation time, as the volume of the tumor cell population changes and the position moves slightly, the target of tumor treatment will move and transform to the periphery of its original position, This further leads to the deviation of the radiation angle and the inaccuracy of the radiation dose, so that th...
