The High-Resolution X-ray Computed Tomography Facility at The University of Texas at Austin (UTCT) is a national shared multi-user facility supported by the Instrumentation and Facilities Program of NSF's Earth Sciences (EAR) directorate. UTCT offers scientific researchers across the earth, biological and engineering sciences access to a completely nondestructive technique for visualizing features in the interior of opaque solid objects, and for obtaining digital information on their 3D geometries and properties.

News and Happenings

XRadia MicroXCT sample imagery now available!

UTCT recently expanded our imaging capabilities with the acquisition of an Xradia MicroXCT scanner. This scanner is capable of sub-micron resolution, thus effectively covering the smaller specimen size ranges (<1 cm) previously beyond our capabilities. Click here for sample imagery.
