An idea of Compton-PET is not new, however, current trend to be equipped heavy and smaller scintillators makes this idea feasible and easy. Two layers which composed of 3x3 scintillator matrix read out by 9 MPPC are fabricated and tested. The results of the experiment and comparison to the simulation will be presented. Furthermore, much smaller scintillator makes to improve the SPECT resolution with small PPD which is available in the market. A new SPECT idea with such smaller scintillator and MPPC is also fabricated and tested. The results and comparison to the simulation are presented and discussed.


The compton-PET will reduce the patience dose or the testing time to be 1/3. A new SPECT will increase the special resolution to be comparable 1mm.
