Research Abstract |
With respect to reduction technique of radiation dose in CT using iterative reconstruction (IR) algorithm, we compared IR with widely used filtered back projection (FBP) algorithms and dealt with usefulness of IR algorithm. Especially, we focused on diagnostic acceptability at cardiac region; studied improving in-stent lumen visualization and automatic tube current modulation (ATCM) technique in terms of basic and clinical researches.
