Intended Use

A diagnostic imaging system combining PET and CT modalities to assist in detection, diagnosis, staging, treatment planning and response evaluation for diseases, inflammation, infection and disorders including oncology, cardiology and neurology.

Technology

The device integrates a PET system with LYSO scintillator detectors for high axial field of view (280 mm or 350 mm) and a 160-slice CT. It includes software updates: uExcel Focus (deep learning based motion correction and image enhancement) and uKinetics (generation of direct and indirect parametric images). It maintains CT single modality functionality and uses standard medical device safety and software standards.

Performance

Performance testing included bench testing for dosimetry and image quality confirming equivalence to predicate device. Clinical image evaluation by board-certified nuclear medicine physicians showed improved image quality and diagnostic sufficiency with uExcel Focus deep learning correction, and bench tests showed uKinetics provided quantitatively accurate parametric images.
