Caption: Frog (Gastrotheca fissipes), micro-CT scan. This is the type specimen for this species. Types are the original example against which all descriptions are compared. Micro-CT was used to create a virtual copy of this type specimen. In this image, the soft tissue has been deleted from the data set, revealing just the skeleton. The lens of the eye absorbs X-rays more strongly than the rest of the soft tissue, so it appears to be almost as dense as the bones. 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 360° 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.
