The First Human Images from MARS

MARS scanners go beyond the traditional black-and-white CT to produce color images where different materials can be separated. In the images above, metal, soft tissue, fat and bone are all being identified. We have a commercial small bore scanner and are currently developing a human-scale machine.

Molecular imaging without radiotracers

MARS promises to revolutionize diagnostic imaging by quantifying the elements and compounds of a sample in a single scan. It is the first commercially available 3D spectral (multi-energy) scanner to produce in vivo images with anatomic and molecular quantification at a fraction of the cost, time, and radiation dose of traditional molecular imaging, such as PET or SPECT.

The Medipix spectral x-ray detector technology was originally developed at CERN for the LHC and modified for medical applications; it is the result of 20+ years of collaborative innovation.

Our customers

My lab is pleased to feature the MARS photon-counting micro-CT in our research and development of targeted nanoparticle imaging probes for contrast-enhanced CT and quantitative molecular imaging with spectral (multi-energy) CT.

The MARS system is the only product on the market that enables my cutting-edge research to move forward as fast as possible. We are able to transition seamlessly between translation studies spanning from imaging phantoms to in vivo murine models.

Prof Ryan K. Roeder, University of Notre Dame

The MARS scanner in UOC has provided an opportunity to Christchurch researchers to be at the forefront of developing new clinical applications for photon counting CT modality.

By using this novel system, my research group has produced remarkable results on many aspects of the medical applications of spectral CT imaging such as molecular imaging of tumours, drug delivery, atherosclerosis and bone quality

Dr Aamir Younis Raja, University of Otago, Christchurch

My lab is blessed to have the latest MARS photon-counting micro-CT scanner. This spectral (multi-energy) CT will be used  for preclinical research and development and translation to clinical applications such as targeted nanoparticle imaging and quantitative molecular imaging.

The MARS system is the only product in the market that enables important investigations with photon-counting detectors and redefines the state of the art.

Chair Professor Ge Wang, Rensselaer Polytechnic Institute

The MARS scanner gives us the ability to rapidly and non-destructively characterise atherosclerotic plaques at high resolutions.

Without this technology we would be unable to compare the biochemistry of the plaques and understand the effect of calcification on cell behaviour.
