X-ray micro-CT offers high resolution
imaging of small samples: up to 5-20 micrometres
of spatial resolution on samples with a maximal
size of 3 cm in length. Analysis is non-destructive
and radiographs and CT scans give 2-D and 3-D microscopic
images of the internal structure of small opaque
objects. Radiation imaging is useful in a wide variety
of applications, such as imaging of geological and
biological samples, bone fragments, microelectronics,
composites, building materials, diamonds, diffusion
studies in porous media and quantitative nondestructive
testing.
