Abstract
In an arrangement of light-sensitive or X-ray sensitive sensors (S.sub.1,1, . . . , S.sub.2048,2048) arranged in a matrix in rows and columns, which sensors produce charge states in dependence upon the amount of incident radiation and each have an electrical switch, for each sensor row a switching line (33.sub.1, . . . , 33.sub.2048) via which the switches (3) can be activated so that the charge states of the sensors of the activated sensor row are read or reset simultaneously via associated read lines (8, 9, 10), there is provided a reset device (30a, 30b) for resetting the charge states of previously read sensor rows, which device activates at least one of the previously read sensor rows, which activates another of the previously read sensor rows after a predetermined number of clock pulses of a reset clock signal (T.sub.32), and which deactivates each activated sensor row a predetermined number of clock pulses after its activation.
