Abstract :
The TierPET system, a high resolution 3D positron emission tomograph, has been developed to perform small animal positron emission tomography (PET) studies. High resolution PET opens the possibility to perform animal trials without the need for vivisection. This reduces the expense for such experiments, saving animal lives and cutting costs for example for the development of new radiopharmaceuticals. The scanner uses two orthogonal pairs of detectors consisting of arrays of small individual YAP crystals coupled to position sensitive photomultipliers. The detector-to-detector distance may be varied to improve either sensitivity or spatial resolution. The spatial resolution of the scanner is 2.1 mm
