Figure 3: (a) The graph illustrates a representative subject’s breast volume histogram and corresponding dual-Gaussian fit. The 𝑅 2 value indicates a high quality fit, allowing for various segmentation methods based on the minimum, cross-point, and percentage contribution to be compared. (b) Two normalized representative single-slice histograms from the same subject, along with estimated breast size. The graph clearly demonstrates the shift in attenuation coefficients as a function of object radius.
