X-ray Computed Tomography (CT) is an established 3D imaging technique, well knownfor its medical applications, that is becoming an increasingly valuable method for the nondestructive characterisation of micro structures, material samples and components across a broad range of industrial and cultural sectors.
The CT scanning systems collect a large number of 2D radiographs, which with a 360 degree rotation of the sample are then reconstructed to create 3D volumetric models, using algorithms such as Filtered Back Projection (FBP). The resulting data
set can be visualised and/or analysed in a variety of ways; including images, slice-through videos, geometric quantification, porosity analysis etc.
Whilst CT systems have limitations in terms of the size and density of objects that can be scanned, and resolutions that can be achieved, the Microfocus CT RTP at the University of Warwick has a suite of systems with the ability to scan and image
a broad range of samples, from grains of rice through to automotive engine blocks.
