Abstract

A method for breath compensation in radiation therapy, particularly radiotherapy/radiosurgery, wherein the movement of the target volume inside the patient is detected and tracked in real time during radiation by a movement detector. Adaptation to the movement of the target volume inside the patient is achieved by one or more components of a radiotherapy apparatus to compensate for or take into consideration the movement during treatment.
