Assessment of an iterative reconstruction algorithm (SAFIRE) on image quality in pediatric cardiac CT datasets
30 April 2012
B. Kelly Han, Katharine L.R. Grant, Ross Garberich, Martin Sedlmair, Jana Lindberg, John R. Lesser
Background: Pediatric cardiac patients often undergo repeat diagnostic testing, resulting in relatively high cumulative medical radiation exposure. Low-dose CT scanning techniques used to decrease rad...
