One-week Short Course on Practical StereologY North Carolina State University, Raleigh, NC (U.S.A.), October 13 - 17th, 1986, at the university’s McKimmon Center for Continuing Education. Stereology is the study of three-dimensional structures as revealed in twodimensional images. It is particularly useful with images from the light microscope and both transmission and scanning electron microscopes. Simple measurements performed on these two-dimensional images can be straightforwardly interpreted to obtain such values as the volume fraction of a phase or structure, the amount of surface area (and its curvature) of membrane or interface, and the mean free distance between objects. In addition to these ‘global’ measurements, individual features may be measured, from which their true threedimensional size distributions, shape factors, location and orientation may be derived. This course introduces the principal methods of stereology in ways that encourage its practical use. It covers three main topics: Manual methods which may be routinely employed when needed, typically working with photographic prints of micrographs and

Computer-as& ted methods in which images are acquired directly from the microscope or from photographs, and features are discriminated for automatic or semi-automatic measurement. As these image analyzers become more common, users are able to ask more specific questions and obtain more meaningful results. New developments in areas related to stereology but not part of its mainstream, such as stereoscopy (measurement of surface relief from the parallax in two different views), serial section methods and topology (in which the three-dimensional structure is revealed), and fractal surfaces (a means to characterize the roughness of real structures).
