Abstract :
The main purpose of this development is to design an "intelligent sensor", composed of one multi anodes PMT, four custom front-end analog chips with embedded analog to digital converter and a pre-processing logical unit. The idea of this design is to improve as most as possible the treatment speed of signals of the PMT. This design must be compact to fit the PMT dimensions, in order to combine them together to form an assembly which will be used in medical imaging research, especially for gamma-ray camera at 144 keV (99mTc) with NaI(Tl) cristal.
