Its long-term stability is particularly important for clinical applications, especially in longitudinal studies, but systematic evaluation remains lacking. This study aims to comprehensively analyze the long-term stability of the first-generation clinical PCCT scanner. Methods From November 2021 to November 2023, standardized experiments were conducted weekly following the same multi-energy CT scanning protocol, and all software and hardware modifications during the entire study period were meticulously recorded. Weekly scans of various tissue-mimicking phantoms were performed to systematically evaluate the stability of Hounsfield units (HU) and image noise in virtual monochromatic images (VMI) and iodine density maps."]
