Patent ID: 6947086

Claim:
A sensor with a matrix of light-sensitive or X-ray sensitive sensor elements (S 1,1 ; S 1,2 , . . . ) arranged in rows and columns, which sensor elements generate charges in dependence on a quantity of radiation incident thereon, including a respective switch ( 3 ) with an address line ( 4 , . . . , 8 , . . . ) for each sensor line for connection to activation means ( 20 ) via which the electrical sensor switches can be activated, a read-out line ( 9 , . . . 13 , . . . ) for each sensor column via which the charges of the respective activated sensor elements are drained, transmission means ( 19 ) at the end of the relevant read-out line for converting the signals read out in parallel into a serial signal, and a plurality of amplifiers ( 14 , . . . 18 , . . . ) arranged to precede the transmission means, wherein a first unit of switch elements ( 27 , . . . 30 , . . . ) is arranged between the activation means ( 20 ) and the electrical sensor switches, a second unit of switch elements ( 31 , . . . 34 , . . . ) is arranged between the electrical sensor switches and amplifiers ( 14 , . . . 18 , . . . ), and a system ( 21 , 35 ) for controlling the switching operations of the switch elements is included in order to connect each switch element or a read-out line to at least one neighboring lines, and wherein the control system for the first and the second unit of switch elements consists of a first and a second shift register ( 20 , 35 ) with a plurality of shift register elements ( 22 , . . . , 26 , . . . ; 36 , . . . , 40 , . . . ), where each shift register element being associated with one switch element per address line or readout line.
