Data for the 8-mm thick healthy and malignant biopsies with the epithelial cell layer at the center: (a) $N_{\mathrm{s},\eta }(E,4\mathrm{deg})$ for pixel $\eta$ located in the inner ring of 4-deg annulus, (b) $N_{\mathrm{s}}(E=60\mathrm{keV})$ as a function of pixel $j$ in inner ring of 4-deg annulus, and (c) $N_{\mathrm{s}}(E,\theta =4\mathrm{deg})$.
