A detector for detecting the traces of ionizing particles includes a scintillator capable of emitting photons when ionizing particles pass therethrough; a first imager capable of detecting each photon emitted by the scintillator, and a first microlens array, each microlens of the first microlens array being arranged such as to produce an image of the trace of the particles by focusing the photons emitted in the scintillator on the first imager.

Detector for detecting the traces of ionizing particles

Device for locating and imaging gamma or X-radiation sources, comprising: (a) a detection assembly comprising at least two gamma or X-radiation detectors sensitive to position, as well as a coded mask made of a radiation opaque material; and (b) electronic means for processing the electrical pulses provided by said detectors, so as to locate the source and form a bi- or tri- dimensional image thereof. The device is characterized in that the electronic means are suitable for reconstructing a bi- or tri- dimensional image of an X or gamma radiation source by applying a data processing method which combines the principles of Compton imaging and coded-mask imaging.
