IRIS PET, CT, and PET/CT

The IRIS scanner is dedicated to in-vivo preclinical research on small animal such as mice and rats. IRIS is available in single modality PET, CT or dual modality PET/CT. IRIS technology is extremely flexible and an IRIS PET or CT scanner can be upgraded to PET/CT at a later stage.
