Abstract
A radiological image detector of the type formed by a matrix of photosensitive elements, associated with a light source, enables a resetting of the voltages at the terminals of the photosensitive elements, the light source and the photosensitive matrix being connected to each other so as to give the image detector a particularly small thickness. To this end, the light source includes a stack of semiconducting layers forming at least one electroluminescent diode having, as its support, a substrate of the matrix.
