ABSTRACT:
A solid state image converter has light-sensitive cells arranged in a matrix, each cell formed by two oppositely-connected diodes, at least one diode in each cell being a photodiode, and has driver circuits for driving the diodes, that are connected between the respective row and column lines of the driver circuits. The driver circuits electrically reset the diodes individually or row-by-row by clocking. By briefly forward biasing, the individual photodiodes so that they are briefly brought into the conductive state, and are subsequently reverse biased. The solid state image converter can be continuously exposed with x-rays and is employable in an x-ray diagnostics installation.
