Figure 1. Detector dose time series and median filtered signal with analysis windows A and B. Excerpt from lumbar spine frontal (Fuji XG-1).
Figure 2. Detector dose time series with the signal level in analysis window B, LB, decreased by a factor kσ, where k is a constant and σ is the mean value of the variation in analysis window B as estimated by Qn.
Figure 3. Variation of Wilcoxon p-value in a detector dose time series with an abrupt change around image #80 in lumbar spine time series.
