Abstract

The present invention relates to a method for positioning a body (1) for radiation comprising the steps: inserting a position sensor (6) into the body (1); detecting the position of the sensor (6) relative to a point or volume (2) to be irradiated, and positioning the body (1) using signals sensed by the position sensor (6) so that the point or volume (2) to be irradiated is located in a specific site circumscribing an isocenter (3). It also relates to an apparatus for positioning a body (1) including a position sensor (6), which may be placed into the body (1); a controllable patient bench (9) for moving the body (1); a controller (8) which controls the controllable patient bench (9) for moving the body (1) depending on the signals sensed by the position sensor (6).
