Reducing CT radiation dose with iterative reconstruction algorithms: The influence of scan and reconstruction parameters on image quality and CTDIvol
Highlights • Iterative reconstruction (IR) and filtered back projection (FBP) were compared. • CT image noise was reduced by 12.4%–52.2% using IR in comparison to FBP. • IR did not affect high- and low-contrast resolution. • CTDIvol was reduced by 26–50% using hybrid IR at comparable image quality l...
