Figure 3. Box-and-whisker plots of objective analysis of image quality acquired with FBP and SAFIRE algorithms.

Figure 3

Image noises of ascending aorta and pulmonary trunk were significantly lower with SAFIRE algorithm than with FBP algorithm (a). Signal-to-noise ratios and contrast-to-noise ratios of ascending aorta and pulmonary trunk were significantly higher with SAFIRE algorithm than with FBP algorithm (b,c). Center horizontal lines show median values and whiskers represent upper and lower quartiles. ○/•  = outliners.
