Sources that contribute to the system MTF. Left (A & B): Mammography; Right (C & D): Radiography. Top (A & C): Characteristic transfer function of Kα₁, Kα₂ and Kβ₁ emission lines, weighted by their relative intensities to obtain T_K. Bottom (B & D): In addition to T_K, the depth-weighted PSL spread function, $T_{\mathit{PSL}}^G$, the spread function due to imaging plate translation along the subscan direction, represented as sinc(πν_ssτ_D), and the pixel aperture function representing the spacing between adjacent scan lines, T_pix are shown. The resultant system MTF, T_sys and the effect of the Gaussian Laser beam are also shown.
