Paper Abstract

X-ray photon-counting detectors (PCDs) become increasingly popular with applications in medical imaging, material science, and other areas. In this paper, we propose a non-uniformity data correction method for photon-counting detectors based on the first and second moment correction. Using three measure datasets, we demonstrate the method’s efficacy in reducing spatial variance of pixel counts. The results demonstrate that both open beam and projection data can be corrected to nearly perfect Poisson counting behavior in both time and space when photon flux is in the detector’s linear response range.
