Optical grid projection system for surgical applications

摘要

A profilometry system useful for surgeons dealing with malformation of body portions of patients. A collimated light beam is projected through one of a selected number of customized grid patterns so as to impress the selected grid pattern upon the body portion. The surgeon can determine from this impressed grid any deviation from certain "standard" orientation goals and thus what reconstruction is needed to correct for the malformation. The same system can then be used to ascertain the profile after any reconstruction procedures. In the preferred embodiment a slide projector system, with focusing, is utilized for providing the collimated light beam and selecting a desired grid pattern.
