Abstract
A process and related apparatus for reducing noise due to addressing and switching the detection elements in a radiation detecting panel comprising an array of detection elements. Noise reduction is achieved in two steps, first by the use of a sample and hold circuit which compares a first signal indicative of switching noise held in a sample and hold circuit with a second signal which includes the switching noise and the desired data signal. The second step includes further reducing noise in the output signal present during readout of the detection elements by comparing the signal from certain elements in the array which have not been exposed to radiation with the signal from the exposed elements in the array to obtain an output with significantly reduced noise.
