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.

Examples of High-Resolution X-ray CT

Garnet-kyanite schist, pseudocolored 3D reconstructions from CT scans.

Variation in bone density in the skull of the Bottlenose Dolphin, Tursiops

The skull of Rooneyia viejaensis, among the most complete and best preserved primate skulls ever discovered in North America

An asphalt sample and antiphonal: Psalterium, An[t]iphonarium Sanctorale cum Psalmis & Hymnis, printed in Mexico in 1584.

Celebrating our 15th Anniversary!

It has been 15 years since UTCT opened its doors. We would like to thank NSF, the W. M. Keck Foundation, The University of Texas, the Jackson School of Geosciences, and our many clients for their support. We look forward to the next 15!

XRadia MicroXCT sample imagery

In 2008 UTCT 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.
