X-RAY IMAGING MATRIX WITH LIGHT GUIDES AND INTELLIGENT PIXEL SENSORS, RADIATION OR HIGH ENERGY PARTICLE DETECTOR DEVICES THAT CONTAIN IT, ITS FABRICATION PROCESS AND ITS USE

摘要

The present invention refers to a radiation or high energy particles detector, which can be used in obtaining digital radiographic images. The detector is composed of two parts: a scintillator matrix (30) embedded in walls manufactured from a reflector material (10), and a matrix of image elements (pixels), where each element is constituted by a photodetector (21) and an analog to digital converter. The walls manufactured from the reflector material (10) form light guides that prevent the dispersion of the visible light produced by the scintillators (30) and the consequent interference between each pixel and its neighbors.
