UGA’s Georgia Electron Microscopy (GEM) core facility has obtained an X-ray computed microtomography (micro-CT) scanner, an advanced apparatus for non-destructive, three-dimensional imaging that significantly enhances the unit’s imaging capabilities.
Backed by a $1.2 million National Science Foundation (NSF) Major Research Instrumentation (MRI) grant, the new Eclipse XRM-910 Micro-CT from Sigray Inc. generates 3D models from a sequence of 2D X-ray images, maintaining the integrity of the original sample.
“You’re able to image a sample without the necessity of sectioning or modifying it,” stated principal investigator Charlotte Garing, an assistant professor in the Franklin College of Arts and Sciences department of geology. “This allows you to document changes over time as the sample evolves.”
The Sigray scanner provides higher-resolution images and quicker acquisition times for a comparable imaging volume than similar models. It caters to a variety of fields, including archaeology, anthropology, pharmacology, and engineering.
“We had multiple co-PIs on the grant — including Doug Menke from the genetics department, Breeanna Urbanowicz at the Complex Carbohydrate Research Center, and Dan Johnson from the Warnell School of Forestry and Natural Resources — to truly showcase the diverse areas that could benefit from this instrument,” remarked Tina Salguero, academic director of GEM and co-PI on the grant.
The grant also financed three high-performance workstations dedicated to the reconstruction of the 3D datasets and sophisticated image post-processing.
Education and outreach were integral to the proposal. Besides training university students on the equipment, Salguero indicated that GEM intends to inspire K–12 visitors by demonstrating the intricate models generated by the technology.
“The achievement of this [NSF MRI] proposal is attributed to support from the Office of Research,” Salguero mentioned. “The Office of Strategic Research Development team offered guidance and feedback on the written proposal prior to submission.”
In addition to the new micro-CT, the GEM core facility houses other advanced microscopy equipment and employs technical staff, providing resources for research, training, and service functions. It is a participant in the Georgia Research Alliance Core Exchange. For details regarding the lab’s equipment capabilities and pricing, reach out to Managing Director Eric Formo.
