Abstract
In third generation computer tomography apparatus, wherein radiation behind the object is measured by means of a large number of detection elements, a detection device comprises a number of detection elements which is larger than necessary for the measurement of the fan-shaped radiation beam, per se, in a direction parallel to the axis of rotation. Means are included for displacing the detection device in the direction of the axis of rotation. Detector element unbalance effects are thus averaged.
