ABSTRACT:
An X-ray image detecting apparatus having its X-ray receiving plane composed of a two-dimensional array of X-ray sensors and being devised so as to make the picturing of a detected X-ray image free from the brightness irregularity due to the sensitivity variations of the individual X-ray sensors. Each of the X-ray sensors is accompanied by a circuit means for converting the optical output of the X-ray sensor to an electric picture element signal inversely proportional to the sensitivity of the X-ray sensor, thereby enabling a detected X-ray image to be pictured without the brightness irregularity.
