ABSTRACT:
Cone-beam computed tomography method to scan an object using a multi-row detector system. The focal point is displaced on a focal path about the system axis, without any relative movement between the object to be examined and the focal point, in the direction of the system axis. The detector system supplies measuring data corresponding to the received radiation and the length of the focal path is at least the same as the length of a partial contour interval, the length of the interval being sufficient for completely reconstructing a CT image. Raw images are calculated from measuring data from a partial contour interval, the planes of the images thereof being inclined in relation to a central plane containing the focal path, and a plurality of raw images are collected to form a CT image.
