The IRIS XL PET-CT preclinical imaging system is a revolutionary multimodal scanner capable of providing three dimensional CT and PET images of primates and larger animals.

The system is is fully shielded from X-rays and allows for pharmacokinetic PET imaging in single bed position and low dose 4D CT imaging with gating that does not require any ECG or respiratory sensor with PET and CT images automatically fused in the analysis software and automated attenuation correction of PET images from the CT image.

The unique platform provides integrated PET-CT imaging with single modality configurations that can be upgraded at client’s location (PET to PET-CT or CT to PET-CT).
