摘要： 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.

摘要： A method of providing with precision a number of long and narrow through holes (11) in a body (1) made of a high-density material. The body (1) is made in the form of a number of partial bodies (2, 2′, 2″), which are arranged close to each other and from the body (1). Each partial body (2, 2′, 2″) is defined by an outer surface (5), which is part of the outer surface of the entire body (1), an inner surface (6), which is part of the inner surface of the entire body (1), as well as a pair of boundary surfaces (7, 8), which extend from the outer surface (5) to the inner surface (6). Holes (11) are produced by machining at least one of the bounding surfaces (7, 8) adjacent partial bodies (2′, 2″). Each hole (11) extends from the outer surface (5) to the inner surface (6) along said at least one boundary surface (7, 8). The thus machined partial bodies (2, 2′, 2″) are fixedly attached to each other.
