Stereological Analysis of Polycrystalline Microstructure

Revisiting Sphere Unfolding Relationships for the Stereological Analysis of Segmented Digital Microstructure Images

Sphere unfolding relationships are revisited with a specific focus on the analysis of segmented digital images of microstructures. Since the features of such images are most easily quantified by counting pixels, the required equations are re-derived in terms of the histogram of areas (instead of diameters or radii) as inputs and it is shown that a substitution can be made that simplifies the ca...

Stereological analysis of acute lung injury

Acute lung injury is associated with a variety of histopathological alterations, such as oedema formation, damage to the components of the blood–air barrier and impairment of the surfactant system. Stereological methods are indispensable tools with which to properly quantitate these structural alterations at the light and electron microscopic level. The stereological parameters that are relevan...

Stereological Analysis of Mammalian Skeletal Muscle

A quantitative analysis of the volumes, surface areas, and dimensions of the ultrastructural components in the soleus muscle fibers of the guinea pig was made by using point counting methods of stereology. Muscle fibers have structural orientation (anisotropy) and have spatial gradients of the structures within the fiber; therefore the standard stereological methods were modified where necessar...

Stereological Analysis of the Guinea Pig Pancreas

A stereological model which provides detailed quantitative information on the structure of the fasted, nonstimulated gland has been developed for the guinea pig pancreas. The model consists of morphologically defined space and membrane compartments which were used to describe the general composition of the tissue and the specific components of exocrine cells. The results are presented, where ap...
