DOI: 10.1117/1.jmi.8.6.063501
Abstract: Abstract. Purpose: Spatial resolution for current scintillator-based computed tomography (CT) detectors is limited by the pixel size of about 1 mm. Direct conversion photon-counting detector prototypes with silicon- or cadmium-based detector materials have lately demonstrated… read more here.
