Abstract Recent developments in semiconductor pixel detectors allow a new generation of positron-emission tomography (PET) scanners that, combined with advanced image reconstruction algorithms, will allow for a few hundred microns spatial resolutions. Such novel scanners will pioneer ultra-high resolution molecular imaging, a field that is expected to have an enormous impact in several medical domains, neurology among others. The University of Geneva, the École Polytechnique Fédérale de Lausanne, and the University of Lucerne, have launched the 100μPET project that aims to produce a small-animal PET scanner with ultra-high resolution. The scanner will be composed of 4 ”towers”, each containing a stack of 60 monolithic silicon pixel sensors for the direct measurement of the annihilation photons. The sensors are 270 μm thick, providing unprecedented depth-of-interaction measurement. Monte Carlo simulations were done simulating different scanner conditions, resulting in a spatial resolution down to 0.2 mm FWHM and a sensitivity of 3.2%.
