Abstract:
A Compton camera system and method for detecting gamma radiation, comprising a gamma radiation source, at least one fast scintillator plate P1 of which the rise time to peak light is less than 1 ns, having a thickness greater than or equal to 5 mm, equipped with an array of segmented photodetectors ( 5 ) and a dedicated fast-reading microelectronic means. The system is characterised in that it is capable of measuring the spatial and temporal coordinates (X, Y, Z, T) and energy E at at least two successive positions of a gamma photon when said photon undergoes Compton scattering at a first point A before being absorbed at a second point B, by recognising circles of non-scattered photons corresponding to each scintillation interaction. The system has a module for estimating a valid Compton event. The detection system has two scintillator plates P1 and P2.

Claim (Index 9):
The detection system according to  claim 1 , wherein the system further comprises a second scintillator plate, in that the plate is finer than the second plate, in that the thickness of the scintillator plate is such that the gamma photon undergoes Compton deviation at a point A of said plate, in that the second scintillator plate has a thickness for absorbing at least 50% of the energy of the gamma radiation, said second plate being separated from the plate by a distance \u2018D\u2019 of at least 10 mm, preferably greater than the thickness of the thickest plate, and in that it further includes a module for estimating a valid event, said module being capable of measuring on said second plate a coincidence trigger in a time window less than the maximum transfer time of light between the plates and for identifying the valid Compton events.
