Caecilian, micro-CT scan. Caecilians are limbless tropical amphibians that burrow underground. Micro-CT scans can be used to carry out detailed 3D measurements of the skeletons to allow scientists to study comparative anatomy and to describe differences between species. This image was acquired using X-ray micro-Computed Tomography (also known as micro-CT). A micro-CT scanner projects a beam of X-rays through the sample onto a detector panel. Images are collected over a 36MB0?rotation and these are then reconstructed to form a virtual 3D model of the specimen. This virtual object that can be viewed from all angles and sliced open or digitally dissected. Image by Dan Sykes.
