Method And Apparatus For Estimating The Endothelial Cell Density
US Patent:
4340281, Jul 20, 1982
Filed:
Apr 8, 1980
Appl. No.:
6/138366
Inventors:
David J. McIntyre - Bellevue WA
International Classification:
A61B 310
US Classification:
351 6
Abstract:
Endothelial cell density is determined by comparing the specular image of the endothelium at a predetermined magnification with a set of grids each having a plurality of apertures formed in a hexagonal, honeycomb pattern. The apertures in each of the grids are closely spaced and of predetermined size corresponding to a predetermined cell density at the predetermined magnification.
