Microtomography (Micro-CT)

Micro computed tomography or "micro-CT" is x-ray imaging in 3D, by the same method used in hospital CT (or "CAT") scans, but on a small scale with massively increased resolution. It really represents 3D microscopy, where very fine scale internal structure of objects is imaged non-destructively. No sample preparation, no staining, no thin slicing - a single scan will image your sample's complete internal 3D structure at high resolution, plus you get your intact sample back at the end!

How does micro-CT work? A micro-focus x-ray source illuminates the object and a planar x-ray detector collects magnified projection images. Based on hundreds of angular views acquired while the object rotates, a computer synthesizes a stack of virtual cross section slices through the object. You can then scroll through the cross sections, interpolating sections along different planes, to inspect the internal structure. Selecting simple or complex volumes of interest, you can measure 3D morphometric parameters and create realistic visual models for virtual travel within the object.
