The MicroCT Imaging Lab

X-ray microtomography (microCT) provides non-destructive detailed 3D imaging of a wide variety of sample types, from contrast-enhanced embryos and tissue specimens to dried insects and small fossils. We apply microCT to numerous research problems in development and evolution, including comparative embryology, functional morphology, and morphometric studies. We are not a service facility, but we are interested in discussing productive collaborations.

The lab has two microCT scanning systems, both self-contained (i.e. no synchrotron source):

- a Zeiss/Xradia MicroXCT system capable of tomographic imaging of biological objects from about 12mm down to less than 500µm in size, with possible resolutions below 2µm;

- a Bruker/SkyScan 1174 for lower resolution imaging of larger specimens. This is a low-cost scanner made for samples up to about 30mm, and gives spatial resolutions down to about 20µm.
