A medicаl physicist cоmpаres bоne minerаl density (BMD) measurements оbtained from two DEXA systems over a six-month quality assurance review period: System A: Conventional energy-integrating detector and System B: Photon-Counting Detector (PCD). Although both systems operate within quality control limits, System B demonstrates lower measurement variability between repeat scans, improved signal-to-noise performance, and fewer image artefacts. What is the most likely explanation for these findings?
