Figure 1
Fitted spectra sum of the full X-ray emission spectrum from mouse brain tissue presented in Fig. 3[link]. The green, black, red and blue dashed lines correspond to the background, fit, and K and Ca K line emissions, respectively. The solid black, green and blue lines represents the raw X-ray fluorescence, blank (or background) corrected X-ray fluorescence and various other fitted emission lines, respectively. Inset: a close up of both the K and Ca K line emissions, showing both the fitted spectra as well as how window binning using the ROI from channel a to channel b would be applied for Ca Kα quantitation. The K Kβ and Ca Kα are in the same region of interest and thus the K emission will bleed into the Ca signal if the two signals are not properly deconvoluted.
