Abstract

X-ray absorption micro-computed tomography (microCT) and X-ray phase imaging each provide non-destructive views of the interiors of specimens. Here, the two imaging modalities are applied to study biomineralization in sea urchins, which are heavily mineralized invertebrates from the phylum Echinodermata. Following an introduction of the physical bases of the two imaging modalities, laboratory and synchrotron microCT techniques are contrasted, and four methods of X-ray phase imaging briefly described. Examples are presented from the teeth of Lytechnius variegatus and from the spines of Diadema setosum. The value of complementing X-ray imaging with destructive analysis techniques is also discussed.
