Abstract

The Medipix All Resolution System (MARS) is a 3D spectroscopic imaging CT scanner based on the Medipix photon processing x-ray detector. The Medipix hybrid silicon pixel detectors, which were developed at CERN, are capable of high spatial and temporal resolution. Images can be obtained at different energy thresholds offering the potential for spectroscopic x-ray analysis. The present desktop MARS scanner (Figure 1) was constructed through a collaboration of researchers from the University of Canterbury and the Canterbury District Health Board. Mechanical calibration procedures and image quality tests will be presented and the operation and the status of the scanner will be discussed.
