Micro-CT, an abbreviation for X-ray micro-computed tomography, is a non-destructive imaging technique that creates high-resolution, three-dimensional (3D) models of an object's internal structure. Also known as microcomputed tomography or microtomography, these systems are primarily used for industrial and research applications. A key feature is the use of a microfocus X-ray tube, which enables the system to achieve resolutions on the micrometer scale, producing 3D models with voxel (3D pixel) sizes in the micrometer range.
Micro-CT systems are designed in two main configurations. In one, the sample rotates between a stationary X-ray source and detector. In the other, the X-ray source and detector rotate together around a stationary sample. The sample-rotation configuration is standard for industrial micro-CTs, such as those manufactured by Matsusada Precision. The rotating source/detector configuration is typically used for in vivo imaging of animals, where the subject must remain stationary.
Common applications for micro-CT span a wide range of fields, including materials science (composites, polymers, fibers), electronics (electronic devices and components), industrial manufacturing (castings, additive manufacturing/3D printing), geology, and life sciences (pharmaceuticals, biology, food and seed analysis).
