Fig. 27From: Clinical applications of cardiac CT angiographyIterative reconstruction illustrated for a curved MIP of a normal RCA scanned with very low dose technique. a Standard reconstruction with filtered back projection demonstrates a noisey image related to inadequate signal-to-noise characteristics. b Iterative reconstruction using iDose (Philips Medical Systems) with the same raw data demonstrates improved signal-to-noise characteristics with improved definition of the smaller distal RCA branchesBack to article page
