Tracer imaging with a Compton camera

Compton cameras are apposite to imaging of multi-tracer distributions. Though the camera was proposed in the 1970s, practical analytical image reconstruction methods for the cameras were completed after 2000 by the authors, yet problems of scattering angle broadenings were left undone. Of late, the authors have succeeded in developing a method to compensate for the broadenings to the reconstruction method. Evaluations of the compensated reconstruction method indicate that image quality would be competent for biological function studies
