The application of an image analyzing computer (Quantimet 720) for quantitation of biological structures--the automatic counting of mast cells.
A Quantimet 720 image analyzer was utilized in order to 1) quantify mast cells automatically in gingiva and in doing so to 2) investigate the applicability and accuracy of the machine for quantitative analysis of biological structures. The mast cells of two hundred gingival sections were counted first by means of the Quantimet and then by manual count. Results indicated that a) mean counts of mast cells obtained by means of the Quantimet were comparable to that of the manual counts, b) although the spread was larger than by manual methods, the Quantimet automatic image analyzer performed quantitation more rapidly.
