Description

The 100µPET project is developing a pre-clinical medical scanner for positron-emission tomography (PET) with ultra-high-resolution molecular imaging capabilities. The scanner is composed of multiple layers of monolithic active pixel sensors (MAPS) connected to flexible printed circuits (FPC). With pixels of 150 µm pitch and a thickness of 280 µm + 300 µm (MAPS + FPC), the scanner achieves unprecedented volumetric spatial resolution of 0.02 mm³, one order of magnitude better than the best current PET scanners and uniform over the scanner’s field-of-view (parallax free). The MAPS and its design features will be presented, along with the pixel read-out architecture. The construction and quality control of the scanner and its multiple detection modules, prototyped with pre-production chips and FPCs, will be showcased, and the latest imaging reconstruction with simulated high-definition mouse phantoms will be presented.
