Analysis of bright-field TEM images I(x, y) from sections of mouse liver of different thicknesses: (A) 100 nm; (B) 250 nm; (C) 500 nm; (D) 750 nm. Computed images of ln[Iresin/I(x, y)] are shown in (E) for a 100-nm section; (F) for a 250-nm section; (G) for a 500-nm section; and (H) for a 750-nm section. Values for Iresin were obtained by averaging the intensity of pixels contained in regions of clear embedding resin surrounding the cells. Scale bar = 2 μm.
