The ClearPET is a high-performance small animal PET scanner that has been developed by the Crystal Clear Collaboration (CCC) and is now commercially available to customers worldwide through the Raytest group. Its high sensitivity and spatial resolution are achieved, thanks to a patented phoswich configuration made of two types of scintillating crystals: L(Y)SO and LuYAP:Ce, thus providing depth of interaction information. The ClearPET presents a modular design and it allows for 360° rotation of the detector modules around the field of view (FOV). The ClearPET also presents the unique feature of having an adjustable FOV diameter, thus being suitable for small and medium size animal PET studies. This paper shows the performances of the commercial ClearPET in terms of its spatial resolution, sensitivity and quality of phantoms and preclinical images obtained. It also describes the updated situation of the first commercial unit sold to the Animage platform in Lyon.
