To compare digital coincidence detection (DCD) with analog charge summation (ACS) for a cadmium zinc telluride (CZT) photon counting detector (PCD) and evaluate the impact on spatial resolution in PCD computed tomography (CT) as a function of imaging beam ene...

While CT imaging has advanced with improved machine design, further diagnostic information can be achieved by enhancing sensitivity to high-Z therapeutic agents. Current photon-counting CT (PCCT) k-edge imaging sensitivity is limited by spectral overlap betwe...

Dual-energy X-ray absorptiometry (DXA) is the clinical standard for bone mineral density assessment but is constrained by energy-integrating detectors. This study investigates the feasibility of DXA imaging using a benchtop photon-counting detector (PCD).
