Biomedical X-ray imaging quality QC,2D(M, λ), as expressed by equation (15) , in the cases corresponding to some configurations for imaging breast tissue specimens at the IMBL beamline of the Australian Synchrotron (see Tables 1 and 2 ), with 0.1 m ≤ R2 ≤ 20 m, Iin(λ) = 1 µm−2, 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 optimal magnification in this case is equal to MQ ≃ 1.066 (R2 ≃ 8.7 m). |
