All 53 patients had previously undergone contrast-enhanced routine-dose CT with filtered back projection (FBP).
A key requirement of the filtered back projection reconstruction algorithm typically used by CT is for the set of 2-D images to represent a full 360[degrees] rotation of the object relative to the source and detector.
