Abstract

In a procedure for correlating different coordinate systems in computer-supported, stereotactic surgery, without the use of additional referencing markers, partial topographical information is collected by means of a surgical microscope mounted on a carrier system, and this partial topographical information is spatially correlated with the diagnostic data generated prior to surgery using a suitable correlation algorithm.
