Our CT-Equipment and Software Tools

The CT research group of the Campus Wels has four CT-systems. In 2004, the first 3DCT device in Austria was installed at Upper Austria University of Applied Sciences - Campus Wels. Four years later, in 2008, the research group computed tomography bought a second 3DCT device, in order to expand its application areas into sub-µm resolution. In 2015 the group acquired an Phase-Contrast X-Ray Microtomograph. The latest addition is a nanoscale device. Below, further information is given on device specifications and application fields of our CT-systems.
