Measurements Of Electron Microscope Image Content For Biomedical Applications Through A Digital-Optical Process

Hydroxy apatite (Ca10 (PO4) 6 (OH)2) which has a hexagonal crystal pattern is the main inorganic constituant of human bone, and in particular of dental enamel (1). A great controversy has arisen amongst biological scientists concerning the types of defects that lead to cavities formation (2,3,4,5,6). The methods of investigation have not so far made use of the wide potential of image processing. In particular the question of variation of periods of the lattice pattern has not been separated from the distortions that are due to the system (distortions due to electron microscope or to the preparation).
