(a) Photos of the scanned phantom. (b) Sample images from PCD-CT and EID-CT with a routine clinical kernel Qr36 and a sharp kernel Qr54 (similar noise level as PCD-CT). All calcium fragments (0.4 to 0.8 mm) were detectable in PCD-CT images across all phantom sizes. Compared to both the routine and sharp kernel EID-CT images, the PCD-CT images yielded improved visualization of calcification details, better delineation of object boundaries, and better calcium detection. Display window level (WL) / window width (WW): 40/400.
