Abstract
A computer tomography device which comprises means in at least a part of its detector array (5), for forming a difference measurement value between each pair of adjacent detectors which is proportional to the difference of the non-amplified detector output signals. At least one detector of this part is additionally connected to further means (14) which produce an absolute measurement value which is proportional to its detector output signal. Adding means add the difference measurement values to the absolute measurement value.
