Description
Recent generations of ASICs developed at Polimi for medical imaging applications will be presented. ASICs for SiPMs readout of monolithic scintillators allow spectroscopy and position of interaction measurements of gamma-rays, also within a large dynamic range thanks to an active gain control mechanism in the analog channel. Such ASICs are applied, in particular, in prompt-gamma measurements for dose verification in particle therapy. The new ANNA ASIC implements an integrated neural network which processes directly the analog signals from the detectors, towards an on-chip reconstruction of the gamma-ray position of interaction in the scintillator.
