Photon-counting UHRdm: second-best image quality (lower noise) at the same dose of the clinical EICT. UHRnm: same noise but lower dose than the clinical EICT protocol (bottom row). Notice that the XtremeCT scans were conducted without the abdomen phantom in contrast to the UHR and EICT scans. Window C/W in HU for XtremeCT: 463/3207; for UHRdm: 675/2523; for UHRnm: 679/2515 and for EI: 615/2296.
