High resolution preclinical PET/CT for Rodents

The MRS*PET/CT 80 is designed for high resolution imaging for mice, rats to marmosets.

The PET is based on the MRS*PET Clip-On technology, built with the latest silicon photomultiplier (SiPM) technology. The detector assembly (crystal/ SiPM) allows true DOI (depth of interaction) with two pixelated layers of scintillator crystal with different matrices.

The PET has continuous detectors with no gaps between «the rings». The CT is using variable zoom achieving an ultra high resolution of up to 5μm and also dual energy.

Animal Handling

Minerve3MRS systems use Minerve animal handling system. Much more than a simple animal bed for preclinical imagers, the Minerve system provides a well-controlled environment for handling lab animals and plays a critical role in obtaining accurate, reproducible imaging results, while also maintaining each animal’s health and the safety of the surrounding lab environment.
