NSF autopsy tissue: (A) the tricolor RGB map (Gd, Fe and Zn, respectively) obtained from full-spectrum fitting. (B) The tricolor RGB map, identical in construction to (A) except the image was obtained using abridged spectral fitting with a 70% threshold. (C) shows the spectral region from 4 to 10 keV (containing the overlapping fluorescence lines for the K emissions from Mn, Fe and Zn, with the L1, L2 and L3 emissions for Gd), for the summation of the fitted spectra from full-spectral fitting (A). (D) shows the same spectral region as (C) for the summation of fitted spectra using abridged spectral fitting with a 70% threshold. Scale bar measures 100 µm horizontally and 10 µm vertically.
