Figure 6From: Effective x-ray attenuation coefficient measurements from two full field digital mammography systems for data calibration applications Percent glandular map individual sector example for the Mo/Mo – 26 kVp settings. The (logarithmic response = z, theoretical percent glandular composition) ordered pairs are represented by diamonds, and the (z, regression fitted value) ordered pairs are represented by a solid line. Absolute difference between the known and fitted values was 1.7% for all points. This corresponds with the map shown in Fig. 5.Back to article page
