Fig 5. Bland Altman plots of SNR and CNR.

Fig 5

The percentage relative deviation of SNR and CNR of each measurement point from the mean relative deviation for that particular IR level from FBP/QDS is plotted against the corresponding FBP/QDS measurement. Distal segments (RCA3, LAD3 and LCX3) are shown as open marked dots. Mainly, the relative deviation of SNR and CNR in distal segments is not significantly different compared to that of proximal segments; a: AIDR mild; relative deviation is less than 2% of the mean relative deviation of all segments, b: AIDR standard; Relative deviation is less than 1.5% of the mean relative deviation of all segments, c: AIDR strong; Relative deviation is less than 4% of the mean relative deviation of all segments.
