Abstract
Volumetric imaging on a radiotherapy apparatus, wherein a body, of which a volumetric image data set is to be produced, is positioned on a couch of the radiotherapy apparatus, and the couch or a bearing area of the couch or the body itself is rotated about a spatially fixed axis. During rotation, multiple x-ray images of the body or of a part of the body are produced and stored by at least one radiation source/image recorder system which is separate from the radiotherapy apparatus and whose radiation path is substantially not parallel to the spatially fixed axis. The rotational position of the couch or the bearing area of the couch or the body itself is detected while the images are produced, and the rotational position is assigned to the corresponding image, wherein a volumetric image data set of the body is reconstructed from the x-ray images by image processing and assignment by a computer system.
