In order to initiate a quality control (QC) process for clinical photon-counting computed tomography (PCCT), this work evaluates the applicability of AAPM Task Group Report 299 (TG299) for multi-energy CT (MECT) systems to PCCT, highlighting gaps in and recom...

The modulation transfer function (MTF) is a standard metric for quantifying the spatial resolution of radiographic imaging detectors. Measurement of the MTF can be achieved through the Noise Response (NR) method, which utilizes only flat-field images for MTF...
