MARS Bioimaging and MediLumine Announce Partnership

Mars Bioimaging and MediLumine announce a partnership to develop applications for life science research and jointly announce the success of a pilot study using MediLumine’s contrast agents and the MARS color x-ray imaging system.

Prof Phil Butler displays the area of his wrist that was scanned as one of the first human images taken with the MARS scanner.

In this study, the MARS scanner simultaneously identified and quantified three MediLumine contrast agents, Fenestra VC, Mvivo Au, and Mvivo BIS in a phantom with vials of the contrast agents.  The different contrast agents can be visualized in 3D and assigned different colors based on the ability of MARS technology to detect the differences in attenuation slopes and k-edge jumps.

Representative mass attenuation vs. energy of different materials illustrating how multiple contrast agents can be simultaneously identified and quantified. The different materials in the contrast agents can be measured based on differences in attenuation slopes and k-edge jumps. Each material is then assigned a different color for visualization.

The MARS scanner enables simultaneous visualization and quantification of contrasting agents in vivo.

MediLumine and MARS will now work jointly to develop applications and related technical resources to facilitate applications for contrast enhanced color X-ray imaging.

I’m really excited about this partnership as it combines the power of MARS quantitative imaging with the MediLumine’s functional contrast agents. The combination of the two technologies greatly increases the opportunity for novel molecular imaging for pre-clinical researchers.

Working with MARS Bioimaging unlocks the potential of color x-ray imaging by providing a means to visualize disease in ways not yet imagined. Contrast enhanced color x-ray imaging will become a powerful tool in understanding human diseases and advancing drug discovery programs internationally.
