Claim 15:
16. A PET and Compton imaging method implemented by a device including at least two facing PET modules, wherein it comprises at least one Compton camera arranged outside a plane containing said PET modules for forming a trihedron with said PET modules and producing at least one Compton view, the acquisition fields of said PET and Compton views having at least one overlap area covering the object to be imaged, said device allowing the following steps to be carried out:
acquisition of at least one Compton view;
location of a dense area and its contour on said Compton view;
Computation of the 2D map of the probability of detection of the presence of a source from said Compton view of said Compton camera;
Coincidence detection by the PET cameras and association of a response line (LOR); and
Segmentation of LORs crossing the dense area by using the detection probability determined by said Compton view.
