MPPC module for PET
Hamamatsu TOF PET module has a highly accurate photon arrival timing
measurement function that enables PET imaging with high sensitivity not
possible with the conventional Non-TOF PET system.
This PET module is optimized to TOF-PET measurements. The module is
composed of LFS (Lutetium Fine Silicate), MPPC array and signal processing
circuit. The MPPC is best type for PET measurement and the circuit is opti-
mized for Lutetium scintillator (e.g. LFS, LYSO) and MPPC.
The circuit has ASICs for output energy and timing information necessary to
make TOF-PET measurements. The signal processing board is a dedicated
MPPC drive power supply with an auto temperature compensation function.
The module has a good ability of coincidence resolving time (CRT) 280 ps
and low power consumption. The module’s components are suitable for PET application and there is big advantage
for performance and cost.
