Description
The lecture is devoted to the principles, image processing, and applications of X-ray microtomography. It covers the fundamentals of X-ray radiation, including its sources, interaction with matter, and common imaging artifacts. The construction and operation of a microtomograph are presented using the UnitomHR scanner as an example, along with the complete imaging workflow—sample preparation and mounting, selection of scanning parameters, data reconstruction, and image analysis. The lecture also discusses methods of three-dimensional image processing and analysis, such as segmentation (thresholding, contour-based, watershed, and deep learning-assisted methods), morphological and logical operations, surface and volumetric reconstruction, as well as quantitative spatial analysis involving measurements of volume, porosity, layer thickness, and phase distribution. Particular attention is given to practical applications of microtomography in science and industry, including biomedicine, biology, materials engineering, the food industry, geology, automotive engineering, and cultural heritage conservation. The lecture also addresses in-situ experiments that enable real-time observation of physical and biological processes, known as 4D imaging.
