eXplore Vista PET
The GE Healthcare eXplore Vista PET scanner is optimized to accurately quantify and visualize positron-emitting tracers for pre-clinical imaging research. The eXplore Vista provides high sensitivity and spatial resolution without compromising radial resolution uniformity.
The image quality of the eXplore Vista PET is due to its depth-encoding, dual-layer Phoswich detector technology. This unique technology employs both GSO and LYSO scintillation crystals to acquire depth-of-interaction information, resulting in enhanced resolution and sensitivity across the entire radial field of view, not just at the center.
