Patent Images
1. A method for performing a three-dimensional virtual examination of at least one object comprising:
- scanning with a scanning device and producing scan data representative of said object;
creating a three-dimensional volume representation of said object comprising volume elements from said scan data;
selecting a start volume element and a finish volume element from said three-dimensional volume representation;
generating a defined path between said start and finish volume elements;
performing a guided navigation of said three-dimensional representation along said path; and
displaying in real time said volume elements responsive to said path and an operator'"'"'s input during said guided navigation.

Abstract
A system and method for generating a three-dimensional visualization image of an object such as an organ using volume visualization techniques and exploring the image using a guided navigation system which allows the operator to travel along a flight path and to adjust the view to a particular portion of the image of interest in order, for example, to identify polyps, cysts or other abnormal features in the visualized organ. An electronic biopsy can also be performed on an identified growth or mass in the visualized object.
