µ-VIS: Multidisciplinary, Multiscale, Microtomographic Volume Imaging

About the Centre

A dedicated centre for Computed Tomography (CT) at Southampton,

providing complete support for 3D imaging science, serving Engineering-, Biomedical-, Environmental- and Archaeological Sciences

The centre encompasses six complementary scanning systems supporting a wide range of sample sizes with imaged volumes up to 1.5 x 1 x 1m, and spatial resolutions down to approximately 200nm. The various scanners are detailed below. Scanner selection depends on the specimen’s size, material properties such as the density or atomic number of constituent elements, any imposed scan time limitations, as well as the required resolution.

If you have any questions or wish to discuss your needs, please contact us.
