Article Title: Six iterative reconstruction algorithms in brain CT: a phantom study on image quality at different radiation dose levels
doi: 10.1259/bjr.20130388
Figure Lengend Snippet: Objective evaluation of low-contrast resolution—cumulative contrast-to-noise ratios (CNRs) from all three nominal contrast levels (0.3%, 0.5% and 1.0%), for all combinations of radiation doses and reconstruction algorithms. FBP, filtered back-projection; IMR, iterative model reconstruction; IR1–3, iterative reconstruction, Levels 1–3; Veo, a model-based IR algorithm. See Table 2 for system names and full manufacturer details.
Article Snippet: A comparison of cumulative CNR between CT systems revealed highest overall CNR for Philips IMR (10.2 at 120 mGy) and Toshiba IR3 (10.1 at 120 mGy).
