Abstract
A device is provided for recording in at least two planes radiation from a radiotherapy apparatus. The device comprises a dimensionally stable frame which is adapted to be arranged in a defined position relative to the radiotherapy apparatus, an attachment on the frame for a recording means, and a recording means which extends from the attachment at an acute angle to the frame along an axis of rotation and to the center of the frame. The recording means is adapted to assume at least two defined rotational positions on the axis. In addition, the recording means exhibits a surface for supporting a radiation recording unit, which surface is located in a plane that forms an acute angle with the axis of rotation, the plane of the surface when rotating the recording means being adapted to turn on a single pivot point which is fixed relative to the frame.
