X or gamma rays detector, especially for radiology; X ray apparatus comprising such a detector

摘要

The detector according to the invention relates to the field of detection of the X or y photons. It is particularly suitable as a measuring chamber Classic Radiology and as detector scanography.; It comprises at least one transformer (4, 5) of the X or y pictures into light photons and at least one transformer (1) of the light photons to electrical signals representative of the energy of the X photons or there incidents. The transformer (4, 5) X-ray photons or are light photons, comprises a photoconductive layer (5) and a light emitting layer (4) between two electrodes (3, 6) which are raised to a bias potential (U) . The electrode (3) transfer can be constituted by a Schottky barrier.; The light photons transformer signals (S) comprises a photosensitive layer (1), such as a photovoltaic cell on a substrate (2).
