Abstract:
A process for detecting and analyzing the interaction of gamma and X-rays with an object to be studied, such as a patient, the process using an emitter selectively emitting radiation and placed on a first side of the object, wherein the process comprises the following steps:placing on a second side of the object to be studied a first material which is able to emit, as a result of pass-through radiation, i.e., that which has been emitted from the emitter and passed through and interacted with the object, particles charged with high energies; interposing in the path of these particles a second material capable of emitting, after interaction with the particles, a Cherenkov radiation, the refraction index of this second material being selected in such a way as to allow Cherenkov emission only above a defined energy threshold of said particles and to eliminate all contribution of scattered rays; detecting the Cherenkov radiation and its spatial distribution; analyzing the detected radiation.
