Use of X-ray microtomography methods in comparative anatomy

Investigator: M. Hain

The X-ray microtomographic method of 3D imaging of biological objects was used in an extensive study focused on the comparative anatomy of legless lizards (Anguine Lizards) with emphasis on the species Pseudopus Apodus. Methods of data filtering, rendering and image segmentation were developed within the optimized microCT imaging.
The comparison showed significant morphological differences of Pseudopa vertebrates compared to Anguis and Ophisaurus, the results of which were published in CC journal [1].
