  • Abstract
    We have developed a real-time digital pulse-shape analysis system for a Ge Compton camera. We successfully demonstrated the improvement of the intrinsic position resolution using the digital pulse-shape analysis. A test measurement with a 54Mn point source showed that the spatial resolution of the Compton camera with the digital system were improved about 1.5 times. The first imaging of an RI phantom, that has 2D hot spots filled with 64Cu of 3 MBq, demonstrated that few millimeter spatial resolution was achieved with our new system.
