Stereology
In this simplest form, sterology is the science where information about a three dimensional object is obtained from only a two-dimensional section of that structure.
Measurements are usually made with these graticules in the following manner:
- An adequate representation of sections of a specimen is obtained.
- The graticule is superimposed upon the specimen (or micrograph/projected image of the section).
- Finally, the interaction between the superimposed graticule and the test sections are recorded.
An overall introduction is given by: L.B. Brianrty. "Stereology: Methods for Quantitative Light and Electron Microscopy."
