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 comprises multiple layers of monolithic active pixel sensors (MAPS) connected to flexible printed circuits (FPC). With pixels of 150 µm pitch and a thickness of 270 µm + 300 µm (MAPS + FPC), the scanner achieves an 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 scanner's detection layer is composed of 2x2 MAPS, with Au stud bumps on the IO bonding pads, flip-chipped to the read-out FPC, with ENIG plating. The bonding is done with an epoxy paste and low-temperature thermocompression. We will showcase the construction and quality control of the scanner and its multiple detection modules, prototyped with pre-production chips and FPCs, as well as the MAPS design features and the latest imaging reconstruction with simulated high-definition mouse phantoms.
