Glass Siphonophora, micro-CT scan. This glass sculpture of Physphora hydrostatica was crafted in the mid-19th Century by father-and-son team Leopold and Rudolf Blaschka. 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 Farah Ahmed.
