Patent Images
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.

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.

4. A method for correlation of different coordinate systems in computer supported stereotactic surgery without use of referencing markers, comprising:
-
using a surgical microscope (1) mounted on a carrier system (2), providing specific anatomic details of a field of view under observation with at least one contour (6) in diagnostic data generated prior to surgery, projecting said at least one contour (6) into observation optics of said surgical microscope (1), and positioning said surgical microscope (1) over said field of view under observation by means of said carrier system (2) so as to obtain optimum coincidence between said at least one contour (6) and a viewed object structure. - View Dependent Claims (5, 6)
