Abstract

A prototype molecular imaging system that features wide-band imaging capability from 100 keV to MeV was developed based on a germanium Compton camera. In this system, radiotracer imaging is performed through the Compton imaging technique above 300 keV and through the coded mask imaging technique below 200 keV. For practical use, small animal imaging requires spatial resolution of the order of millimeters. We conducted tests with a multiple-well phantom containing 99mTc (140 keV) and 54Mn (834 keV), and confirmed the spatial resolution of better than 3.2 mm for the phantom placed 35 mm above the detector. We also report imaging results of a living mouse into which we injected 99mTc (140 keV) and 54Mn (834 keV).
