Automatic image quality evaluation in digital radiography using for-processing and for-presentation images.

For SNR, the variation in raw images exhibited a strong positive trend (logarithmic), whereas conversely for clinical images a negative trend (logarithmic) was observed, which if the first data point is ignored it becomes very strong (from −0.43 becomes −0.96).

Experiment 3 : Regarding the effect of increasing IAK on the IQ‐scores (reported in Table 1 ‐Block 3 ), as can be seen in Figure 3 , the horizontal MTF 50% exhibited a positive trend (i.e. the MTF 50% increased with increasing IAK), which however numerically was trivial, since the largest max/min ratio was 1.06.
