Reconstruction of electronically collimated images obtained from single photon emitters using a spherical system of coordinates

An algorithm has been developed to mathematically map planar scintillation camera images onto a spherical surface and subsequently reconstruct images also on a spherical surface. This technique results in an increase in the computational efficiency of iterative reconstruction techniques used to reconstruct electronically collimated images of single photon emitters. Results are presented using a prototype electronically collimated gamma camera under development in the laboratory
