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.
Claims19
A method for breath compensation in radiation therapy, said method comprising:
- detecting movement of a target volume inside a patient;
- tracking said movement in real time using a movement detector during radiation;
- detecting an offset based on varying underlying volumes of lung capacity for the patient;
- tuning breath compensation to the offset;
- and
- wherein adaptation to the movement of the target volume inside the patient is achieved by means of one or more components of a radiotherapy apparatus, to compensate for said movement during treatment.
