Abstract

A method for detecting ionizing radiation using a pixelated semi-conductor detector. When the radiation interacts with the detector, the affected pixel is determined, together with the instant of impact for this pixel. A first instant before and a second instant after the instant of impact are deduced from this. The deviations of the signals coming from an assembly of pixels adjacent to the affected point are then measured, with the deviations being measured between the first and second instants. The position of the point of interaction of the radiation with the semi-conductor is estimated from the deviations thus measured.
