X-Ray Microtomography
2024 Scholars Week Scientific Image Competition Best Micro-CT Image Winner: "Varied Thrush Skull" by Carly Hopp
About
Micro-CT (computed tomography) is a non-destructive imaging technique that provides high-resolution, three-dimensional images of small objects or samples. It operates on the same principles as medical CT scanners but is designed for much smaller specimens, typically on the scale of millimeters to a few centimeters. The micro-CT rotates a sample while capturing X-ray projections from various angles, which are then reconstructed into a detailed 3D image using advanced computer algorithms. Micro-CT is used in various fields such as materials science, biology, archaeology, and geology, enabling researchers to visualize internal structures, porosity, and other fine details without the need for sample sectioning. Its versatility and precision make it a valuable tool for non-invasive investigation and analysis at the microscale.

The Micro-CT requires independent users to complete X-ray radiation safety course.
NeoScan N80 X-Ray Micro-Computed Tomography Scanner
The Neoscan 80 has a 16 W X-ray source and can scan with X-ray energies up to 110 keV. It is best for small, cm-scale specimens, especially if specimens are dense. It can achieve a resolution as low as 2 micrometers and up to 43 micrometers. Scan times take as little as ~5 minutes for small, low density specimen and several hours for large and/or high density specimens.
Sample Preparation
Most samples require little preparation before scanning. Specimens should be as small as possible and cannot exceed 10 cm x 10 cm x 20 cm in size. Specimens will be secured to the specimen stage with orthodontic wax, tape, or other mechanical means. Other than sizing the specimen, micro-CT is non-destructive. Some samples may require staining to achieve useful image contrast (for example, soft tissue specimens). Please contact us with any questions you have.
