XRF maps with localized POI and XANES spectra at the Fe K-edge (patients 10 and 11). A reference spectrum of an iron oxyhydroxide compound (FeOOH) is also shown as comparison. (a) Patient 10, optical microscopy HES ×40. (b) Patient 10, optical microscopy, HES ×400 [corresponding to the red rectangle on panel (a)], with clear identification of dark ink. (c) Patient 10, Fe XRF map. (d) Patient 10, XANES spectra at the Fe K-edge. (e) Patient 11, Fe XRF map. (f) Patient 11, XANES spectra at the Fe K-edge.
