Figure 5From: A comparison of calibration data from full field digital mammography units for breast density measurementsCalibration curves for H 3 and GE units. This shows the fitted adipose (solid) and glandular (dotted) calibration curves for the H3 (left) and GE (right) units. The measured logarithmic relative response (LRE) quantities are averages represented by squares. The top plots show the Mo/Mo target/filter combinations acquired with 28 kV and the bottom plots show the Mo/Rh combinations acquired with 28 kV.Back to article page
