This preclinical system is a fully integrated molecular imaging system PET/SPEC/CT for biomedical research and pharmaceutical development. Equipment providing high quality images and data for optimal resolution, contrast, noise-to-image quality and accurate 3D rendering with minimal x-ray dose. CT detector with 120x120 mm of active area and 50 µm of pixel size; PET detector with an axial field of view (FOV) of 11.8 cm and a inner ring diameter of 16.5 cm; the SPECT gamma camera provides a total of 80x80 pixel array within the FOV of 12.7x12.7 cm.The system is designed to hold up to four identical high resolution, small FOV gamma camera heads, each equipped with interchangeable pinhole or parallel hole collimatorsAvailable at the Centre for Pre-Clinical Imaging of the University of Torino, Bioindustry Park S. Fumero, Colleretto Giacosa (Torino).
