Device for correlating different coordinate systems in computer-assisted stereotactic surgery

摘要

The correlation system allows correlation of different coordinate systems, without requiring additional reference markers, using topographic partial information obtained via an operating microscope (1). The top graphic partial data is spatially correlated with pre-operative generated diagnosis data, using a correlation algorithm. Pref. the operating microscope (1) is supported by a carrier (2), for scanning a given surface area of the examined object, with measurement of the distance to each point of the object surface, to provide a 3-dimensional surface profile, used as the topographic partial information.
