Stereological services

Stereology makes it possible to count the number of objects in a three-dimensional structure from a two-dimentional section.

Based on a set of mathematical and statistical principles, stereology is used to obtain quantitative information through a three-dimensional interpretation of a material from measurements on 2-dimensional sections or scanned images of for example brains, bones and lungs.

Stereology gives you a robust and unbiased result that you can count on!

Avoid methodological errors in your results by using Systematic Uniform Random Sampling (SURS) and the disector-principle. When applying these methods, the objects in a structure have an equal probability of being counted regardless of size, shape and orientation.

By applying unbiased stereology using the newCAST software system from Visiopharm we are able to quantify:

  • particles in thin and thick sections (physical and optical disectors),
  • the volume and area of any object (cavalieri’s estimator),
  • the volume and surface area of particles (optical rotator),
  • the surface and length of particles and objects (probes).
