Fig. 5.

Examining X-ray data reveals hidden sub-surface features. (A) Photo-micrograph of a mounted 3-view sample coated in gold palladium. (B) Virtual slice through X-ray volume showing the presence of a Trichuris parasite (W) embedded in the stained cecum tissue (SC). The shape of the resin block (R) can be seen as a white outline caused by X-ray absorption from the gold palladium coating. (C) Volume rendering of T. muris (green), showing its positioning within the fragment of gut tissue. The anterior region of the worm, which is the region of interest, is marked by a blue arrow. Scale bars 500 µm. (For interpretation of the references to colour in this figure legend, the reader is referred to the web version of this article.)
