Longitudinal Quantitative Assessment of 40 keV Photon-Counting CT Artifacts for System Stability and Detector Performance Evaluation

Ring artifacts were observed on our photon-counting CT (PCCT) daily quality control images, with 40 keV virtual monoenergetic images (VMIs) exhibiting the most pronounced artifacts. Because these artifacts may reflect degraded system stability and detector pe...
