Fig. 5

Scatter plot of air kerma (Kair) in front of the thyroid protection device with body mass index and so, approximately, with breast volume. The BMI correlates less (R = 0.48) to backscatter than compression thickness because even large breasts may sometimes have only a thin compression thickness. Therefore, the determining factor for backscatter is compression thickness: Kair =  − 60.75μGy + 10.29μGy ⋅ BMI.
