1. A method for correlation of different coordinate systems in computer-supported stereotactic surgery without use of referencing markers, comprising:

  • moving a surgical microscope (1) mounted on a carrier system (2) over a specific surface area of an object under observation,continually measuring distances between surface points on said surface area and said surgical microscope point-by-point to generate a three-dimensional surface profile of said surface area, andspatially correlating said three-dimensional surface profile with diagnostic data generated prior to surgery via a correlation algorithm.
