摘要:
A graphical model provides a dynamic representation of the endoscopic view and viewing direction relative to a virtual world. The model can be oriented and adjusted to approximate a real world situation. Angular image navigation coordinates are also provided.
摘要:
A method and system are provided for configuring a variable direction of view endoscope, generally comprising a video display screen and an endoscope having a view controlling device for moving the view vector between predefined, discrete view vector positions. The video display screen displays a set of these view vector positions, and the view vector is moved from one of these positions directly to another in response to a command from a user via the video display screen.
摘要:
A method is disclosed for displaying endoscopic images that includes three-dimensional surfaces, variable viewing points, directions, and orientations. A computer receives a captured endoscopic image. A virtual surface is defined in the computer with the captured image textured onto the virtual surface. A virtual viewing point, virtual viewing direction, and virtual viewing orientation are defined relative to the virtual surface. A rendered image of the virtual surface is then created. The rendered image is displayed to the user. Video is displayed on the virtual surface by updating the image texture with each new frame.
摘要:
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.

摘要:
A method for avoiding rapid or sudden image rotation or reversal in a gravity leveled endoscopic imaging system is disclosed. A mathematical neighborhood of a singular viewing configuration is defined and within this neighborhood the endoscopic image orientation follows specified rules.
