RADIATION DETECTOR ARRANGEMENT COMPRISING MULTIPLE LINE DETECTOR UNITS

摘要

A radiation detector arrangement for imaging of an object comprises multiple line detector units (41), each being arranged for one-dimensional imaging of the respective ray bundle. The detector units are arranged parallel in a two-dimensional array. The detector units are sited in rows (44; 61) and stacks (45; 63), the rows being parallel with the detector unit and the stacks being orthogonal thereto, where the one-dimensional detector units in each row are together capable of detecting the object in one dimension. A device (87-89, 91) is provided for moving the detector units relative the object parallel with the stacks at least a distance corresponding to the distance (s<1¿) between two adjacent detector units in the stacks.
