Overview PET/CT technology

MRS*CLIP-ON Technology for PET/MR & PET/CT

MRS*PET/CT’s are based on the MRS*PET CLIP-ON technology. It is a unique plug and play concept making the same PET component compatible with CT and MR up to 9.4T. This modular approach offers significant advantages in efficiency and workflow, and most importantly, considerably reduces the investment for the research institute.

PET Technology: True Depth Of Interaction (DOI)

The MRS*PET for small animal imaging uses the latest silicon photomultiplier (SiPM) technology. The detector assembly (crystal/ SiPM) allows true DOI (depth of interaction) with two pixelated layers of scintillator crystals with different matrices. This design enables the MR SOLUTIONS PET module to reach under 0.8mm resolution.


CT Technology with variable zoom and dual energy

MRS*PET/CT 80 and MRS*PET/CT 120 have a variable zoom allowing high resolution up to 5μm. These systems are suitable for both in-vivo and ex-vivo applications.

Animal Handling and monitoring

MRS*PET/CT’s use advanced animal handling and animal monitoring systems. Much more than a simple animal bed for preclinical imagers, the system provides a well-controlled environment for handling lab animals and plays a critical role in obtaining accurate and reproducible imaging results.

Preclinical Scan: Multimodality imaging Software

Preclinical Scan is the multimodality interface for preclinical imaging. Under one interface users have access to all MRI functionalities such as adjusting MRI pulse sequences parameters, but also have access to the PET, SPECT and CT extended functionalities.We have designed the graphical user interface to be friendly and easy to set up, even for the new user. For the advanced user, real-time optimisation and advanced functionalities are available. Preclinical Scan software can be configured with different levels of access depending on the experience of designated users.Learn More
