MARS imaging and reconstruction challenges

The MARS programme is developing spectral CT scanners to advance medicine. Our system is built upon the Medipix3RX ASIC developed by a CERN led collaboration. The Medipix3RX has 8 counters where some counters use charge summing technology to improve energy resolution. Our scanners include small bore scanners, pre-clinical systems used by our partners at the Mayo Clinic, Notre Dame University, and the University of Otago, and a large bore scanner (a human scale system in development). In this talk we demonstrate some of the applications, and publicly available datasets, that show how spectral CT can enhance pre-clinical and medical imaging. Our primary challenge for the future is to improve our reconstruction methods to generate artefact free, quantitative material volumetric datasets for clinical use.
