MARS Imaging: Biomedical 3D spectroscopic X-ray imaging Anthony Butler

Goal To bring spectroscopic X-ray imaging into medical use X-ray Detector Technology Clinical Application Our team is bridging this gap

Overview X-ray source Object Pattern Recognition System Detector

The Team Technical team University of Canterbury Clinical team University of Otago International Partners Incl. CERN, Cambridge Uni and Erlangen Uni The company MARS Bioimaging Ltd

Benefits of Spectral X-rays Better image quality  Less artefacts eg. Around coronary artery stents K-edge imaging  Better use of contrast agents eg. Less scanning Intrinsic tissue contrast  eg. Breast cancer from normal tissue

Polychromatic Bone Soft tissue Gadolinium Modelled using the 8 energy thresholds Potential of full body imaging

The MARS Scanner M edipix A ll R esolution S ystem Energy resolution Spatial resolution Temporal resolution Desktop microCT (x-ray) -Small animal studies -Pathology studies

Medipix Spectroscopic Photon Processing Detector 17 Institutes, 12 years Hosted by CERN We provide Test-bed for technology Application development First clinical experiments

First MARS medical scan Iodine contrast 12 keV17 keV33 keV42 keV

Looks like a “traditional CT” MARS has higher resolution Results: Grey Scale Imaging

12keV17keV 33keV42keV

Results: Spectral Imaging IodineNon-iodine Useful for heart and cancer imaging

Results: Spectral Imaging
