Outline of Final Research Achievements |
GAGG crystal arrays with the pitch of 500 micro meter and 200 micro meter are fabricated for the imaging of cells whose size is approximately from tens of micro meters to hundreds of micro meters. The position discrimination is confirmed with the crystal array coupled to digital silicon photomultiplier (SiPM). The position discrimination and energy histgram is acquired with the crystal array coupled to TSV (Through Silicon Via) type MPPC (Multi Pixel Photon Counter) using charge division readout system. This indicate the possiblity of the order of few hundreds micro meters spatial resolution. The prototype of PET scanner based on digital SiPM is also designed and fabricated.
