MicroCT is a powerful tool that can be used to non-destructively generate high-resolution two- and three-dimensional (2D/3D) representations of an object’s internal and external structure down to the submillimeter, micro- (1–100 microns) and even nano-scales (< 1 micron). Check out our Equipment Page to learn more about the basics of microCT and the specific equipment at MICRO.

MicroCT is applicable to a wide range of disciplines including mechanical engineering, biology, anthropology, anatomy, paleontology, geology, neuroscience, chemistry and biochemistry, human health, biomedical engineering, and beyond. 

Click on the images below to see some examples or feel free to contact us at micro@uark.edu if you are interested in finding out about potential applications of microCT for your own research.

Zoological and anatomical specimens such as hearts, brains, snakes, birds, primates, insects, fish, rats, lizards, alligators, pigs, possums, goats, and many more

Manufactured objects such as computer parts, heart stents, cement, plastic parts, fused metal objects, or 3D printed metal

Geological and paleontological items such as rock samples and cores, as well as fossil remains

Archaeological objects including ceramic vessels, sherds, reed flutes, and seeds

Botanical specimens such as fruits and vegetables, seeds, pinecones, and more
