PBI intensity profiles, expressed by equation (7)[link], in the cases corresponding to some proposed configurations for imaging breast tissue specimens at the IMBL beamline of the Australian Synchrotron (see Tables 1[link] and 2[link]), with M = 1.094 (R2 ≃ 12.0 m), Iin(λ) = 1, and different X-ray wavelengths (energies): λ = 0.4769 Å (E = 26 keV, dotted line), λ = 0.3875 Å (E = 32 keV, solid line), λ = 0.2952 Å (E = 42 keV, dashed line). The dot-dashed line shows the absorption component only from equation (7)[link] in the case of E = 32 keV. The profiles for E = 26 keV and E = 42 keV have been shifted vertically to bring the left ends (which correspond to the absence of the edge feature) to the same fluence level as in the case E = 32 keV, in order to facilitate visual comparison of the contrasts.
