Radiation therapy system for obtaining e.g. three dimensional image data, has patient positioning unit designed such that patient is brought into space in any desired body position in front of irradiation station

摘要

The system has a patient positioning device (3) with a computer tomography unit (CT) gantry (9), which is moveably aligned in a space where images are carried out in a posture of a patient. A storing unit stores a parameter of a patient positioning unit (7), during planning, to determine the alignment of posture in the space. The patient positioning unit is designed in such a way that the patient is brought into the space in any desired body position in front of an irradiation station having a therapeutic beam delivery device (23). Independent claims are also included for the following: (1) a method for planning a radiation therapy of a patient (2) a method for patient positioning during a radiation therapy.
