Software package for the quantitative image analysis of histological sections.

A software package of general interest, and adapted to the analysis of histological sections has been written. The different programs of this package have been classified into four groups: macroanalysis, selection of fields, analysis, and data processing. The macroanalysis allows the acquisition of topographical information that will be used during the selection of fields and the analysis. Mapping programs have been added to the classical data processing of the measured parameters (statistical calculations, edition of values, histograms, graphs, .. .). They allow the generation of parametric images representing the distribution of particular elements in the section, or the topographical variations of calculated parameters. The recombination of information obtained at different magnifications, and the correlation of information of different types is thus possible and of great interest in the study of complex histological structures.
