Fig. 5From: Correlation of clinical and physical-technical image quality in chest CT: a human cadaver study applied on iterative reconstructionMean noise versus mAs for B70, I70/1, I70/3 and I70/5. The error bars in the y direction represent the standard deviation between noise measurements in 11 following slices in the Catphan uniformity module. \( \frac{a}{\sqrt{mAs}} \) regression curves were addedBack to article page
