Method for using variable direction of view endoscopy in conjunction with image guided surgical systems
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.
1. 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.
2. The method of claim 1 , further comprising:
selecting an entry line; and
calculating the intersection of said entry line with said set of possible endoscope tip positions.
