Two-projection moire technique for investigations of the spine's shape in norm and pathology

We proposed the usage of two-projection moire technique for contactless non-invasive investigations of the spine's shape in norm and pathology. The results of investigations for healthy people and for patients having vertebrogenic pathology are presented in the paper. The quantitative interpretation of the obtained moire topograms has been performed. The three- dimensional profiles of the spine surface have been drawn. It is shown, that the suggested method may be used both for screening investigations of various population groups, and to estimate the treatment efficiency of patients with vertebrogenic pathology.
