Abstract
Techniques for controlling a stability of response of a semi-conductor matrix imager composed of pixels, including a first phase of characterizing the stability of the pixels and a second phase of correcting the signals arising from the pixels during the measurements. The pixels are classed into stable pixels and unstable pixels according to a predetermined criterion, the unstable pixels being associated individually with a stable pixel whose characteristics serve as base for correcting signals arising from the unstable pixels.
