Coronary phantom content and imaging. Each column shows a different region of
interest (ROI), with the detailed 5-mm probe content shown in the top row.
Cross-sections of the probe at energy-integrating detector CT (EID; second
row), photon-counting CT (PCCT; third row), and high-resolution PCCT (HR
PCCT; fourth row) with and without stents. Window and level for unstented
cases was 1600 HU and 300 HU and for stented cases was 1000 HU and 250 HU,
respectively. (Reprinted, with permission, from reference 1.)
