ABSTRACT
The concept of Compton camera originates from the need to improve sensitivity in Single Photon Emission Imaging, which uses hole collimators. It advocates electronic collimation which registers radiation emitted by the radiating object and scattered by a scattering detector placed before an absorption detector. The data consists of three dimensional conical projections of the activity density of a radio-tracer. An analytic reconstruction method of this density is presently not available. To evaluate its imaging power, we consider a particular two-dimensional Compton camera in which the collected data consists of the set of integrals of the density on rotating V-lines. In this communication, we present simulation results obtained from an algebraic reconstruction technique, which illustrate and validate the imaging capability of this Compton camera modality.
