Abstract:
A device for recording in at least two planes radiation from a radiotherapy apparatus, in a limited area at which the radiation is directed, wherein the device comprises a dimensionally stable frame (1) which is adapted to be arranged in a defined position relative to said radiotherapy apparatus, an attachment (4) on the frame (1) for a recording means, and a recording means (5) which extends from the attachment (4) at an acute angle to the frame (1) along an axis of rotation (6) and to the center of the frame (1) and which is adapted to assume at least two defined rotational positions on said axis (6), that the recording means (5) exhibits a surface (14) for supporting a radiation recording unit (13), which surface (14) is located in a plane (9) that forms an acute angle with said axis of rotation (6), and that the plane (9) or the surface (14) when rotating the recording means (5) is adapted to turn on a single pivot point (7) which is fixed relative to the frame (1).
