MRS*PET/CT 120
From rodents up to 3kg animals
The MRS*PET/CT 120 is designed for high resolution imaging for rodents up to 3kg animals.
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 very high resolution up to 10μm and also dual energy.

MRS 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.
