Learning outcomes
Stereology is a science about geometrical relationships between a structure that exists in three dimensions and images of that structure, which are usually two-dimensional. These images can be captured in various ways and can be divided into two basic categories: Object cross-section images and object projection. At present, the experimental technique of micro-CT, which can capture three-dimensional structural elements, is intensively developed. Stereology is most intensively used in conjunction with microscopy analysis. These are mainly light microscopes (conventional and confocal), electron microscopes and other types of microscopes. Basic streological methods are also suitable for the study of macroscopic structures. For example, a study of the distribution of stars in the visible universe led to the formulation of one of the stereological rules. Most of the examples discussed in this doctoral study course are in the field of microscopy, as used in the material sciences, as well as in the biology and medical sciences. Stereology has been developed as a mathematical tool for quantitative analysis and description of the internal structure of three-dimensional objects, such as fibre and nanofibrous materials. Estimating volumes, lengths, areas, etc., quantitatively evaluate parameters of geometric shapes.
