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.
