| Research Abstract |
We have evaluated the imaging performance of the semiconductor Compton camera GREI to establish the multiple-molecular simultaneous imaging as an innovative molecular imaging technology in nuclear medicine. We have designed a GREI system for human and found three-dimensional imaging with 2 mm spatial resolution is possible. The improvement of the three-dimensional tomographic imaging performance was demonstrated by an RI phantom imaging experiment with opposed-type GREI system. We have also made a quantitative consideration on the radiation exposure by higher-energy gamma rays.
