What is Micro-CT? How does it differ from a medical CT scanner?

Micro-CT (Micro-Computed Tomography) is an advanced X-ray imaging technology that creates high-resolution 3D models of an object's internal structure. It creates detailed visualizations with spatial resolution in the micrometer (µm) range.

How Micro-CT Works
The system rotates a sample 360 degrees while irradiating it with X-rays. A high-sensitivity detector captures thousands of 2D transmission images (radiographs) from every angle. These images are mathematically reconstructed by a computer to generate a complete 3D model, allowing for non-destructive cross-sectional analysis and internal dimensional measurement.

Micro-CT is also referred to as a "3D X-ray microscope" or "industrial CT." Note that "industrial CT" is a broad term that may also refer to larger systems designed for inspecting engine blocks or castings with lower resolution.

Difference from Medical CT
The primary differences between Micro-CT and medical CT scanners are resolution and application.

• Medical CT: Designed to scan the human body for diagnosis. Prioritizes scan speed and low radiation dose, typically offering resolution in the millimeter (mm) range.
• Micro-CT (Industrial CT): Designed for non-destructive inspection (NDT) and R&D analysis of electronics, biological samples, and advanced materials. It prioritizes high resolution and contrast to visualize microscopic defects and internal structures invisible to the naked eye.
