Method and device for radiographic imaging using gamma rays and X-ray beams

A radiographic imaging system, for restoring in real time one or several images representing an object or a patient subjected to localized radiation, comprising a particle accelerator intended to generate a beam of gamma or X photons, a detector of the particles resulting from the interaction of these photons with the irradiated object or patient, and an element for interpretation of the detection thus performed, wherein the detector detects the interaction of pass-through radiation, namely, gamma rays or X-rays, with an object to be studied, such as a patient, wherein the detector comprises:

• a converter (7) of the pass-through radiation into high energy electrons created by phenomena of pair production and the Compton effect in the process of interaction with the constituting material of the converter;
• a photon emitter by the Cherenkov effect (11) under the action of the high energy electrons originating from the converter (7), this emitter being placed right next to the converter;
• a detection element (20) sensitive to the photons created in this way and capable of reconstructing spatially the emission density of the Cherenkov photons originating from said Cherenkov emitter.
