| Abstract: | This paper presents a new dual-modality imaging principle using two recent results. First we demonstrate the feasibility of reconstruction of a radioactive distribution from its Compton-scattered radiation. Next we show the possibility to reconstruct the electronic density of a medium and its attenuation map from other Compton-scattered radiation emitted by an external gamma source and scattered in the medium. The required data for the two reconstructions are easily acquired from an energy and space measuring gamma camera under the form of scattered distribution images classified by their Compton-scattering angle. The motion of camera is unnecessary and all images needed for a 3D reconstruction are recorded simultaneously. For non-immobile object, this is a decisive advantage. | ||
