Abstract
A method for a variable direction of view endoscope used in combination with an image guided surgical system to provide new diagnostic and surgical capabilities. The method provides the following capabilities: greatly improved endoscopic orientation capabilities, global monitoring of endoscopic viewing direction, and greatly improved surgical approach and procedure planning.
Claims8
A method for improving a diagnostic or surgical procedure involving a variable direction of view endoscope with a variable line of sight comprising:
- acquiring volumetric scan data of a subsurface structure;
- positioning said endoscope relative to said subsurface structure;
- acquiring internal endoscope configuration data;
- establishing the position of said endoscope relative to said subsurface structure;
- and
- based on said volumetric scan data, said endoscope position data, and said internal endoscope configuration data, displaying representations of said subsurface structure and said endoscopic line of sight in their correct relative spatial relationship.
A method for improving a diagnostic or surgical procedure involving a variable direction of view endoscope comprising;
- acquiring volumetric scan data of a subsurface structure;
- selecting a target point relative to said volumetric scan data;
- calculating a set of possible endoscope tip positions from which there is a direct line of sight to said target point;
- and
- displaying said set of possible endoscope tip positions.
A method for improving a diagnostic or surgical procedure involving a variable direction of view endoscope comprising:
- acquiring volumetric scan data of a subsurface structure;
- positioning said endoscope relative to said subsurface structure;
- establishing the position of said endoscope relative to said subsurface structure;
- computing the regions of said subsurface structure which can be viewed with said endoscope from its current position;
- and
- displaying said regions.
