A Compton scatter camera for nuclear medical imaging includes an annular scattered photon detector disposed around a first scattering detector and shielded from the field of view of incident gamma photons. Scattered photons detected by the annular detector are thus scattered through angles greater than those of a conventional Compton scatter geometry. Sensitivity and count rate capability is thus significantly increased over the conventional scatter camera, so as to present the possibility for a commercially feasible Compton scatter camera to be realized.
