First-generation clinical dual-source photon-counting CT: ultra-low-dose quantitative spectral imaging

Objective Evaluation of image characteristics at ultra-low radiation dose levels of a first-generation dual-source photon-counting computed tomography (PCCT) compared to a dual-source dual-energy CT (DECT) scanner. Methods A multi-energy CT phantom was imaged with and without an extension ring on bo...
