Agreement of small pulmonary nodule measurements.

<p>Bland-Altman plots of CT measured nodule volume at filtered back projection (FBP) and iterative reconstruction (iDose⁴ level 2 (A), 4 (B) and 6 (C)) for small nodules. The horizontal axis shows the mean value of the measured nodule volume with FBP and iterative reconstruction. The vertical axis shows the difference between the measured nodule volume with FBP and iterative reconstruction. <i>FBP</i> Filtered back projection; <i>L2</i> Level 2; <i>L4</i> Level 4; <i>L6</i> Level 6.</p

Example of the stents acquired with different protocols: routine dose (195 mAs, 100kV), low dose (195 mAs, 80kV), low dose (80mAs, 80kV).

Noise per dose level for FBP and IR.

<p>The white boxes represent the noise with FBP, while the gray boxes represent the noise with IR. IR resulted in a decrease in noise compared to FBP at the same dose level. <i>FBP Filtered Back Projection</i>, <i>IR Iterative Reconstruction</i></p

Phantom set-up.

<p>A plastic holder containing a stent with inside a balloon (left upper image) was placed into an anthropomorphic chest phantom (right upper image, bottom image) [<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0175714#pone.0175714.ref002" target="_blank">2</a>].</p

Subjective image quality scores.

<p>Scores are displayed as median [interquartile range]. No significant differences compared to FBP at routine dose were observed. <i>1 poor</i>, <i>non-diagnostic image quality</i>, <i>2 moderate</i>, <i>limited diagnostic value</i>, <i>3 good</i>, <i>diagnostic image quality</i>, <i>4 excellent</i>, <i>excellent image quality</i></p
