Abstract

A system and method are provided 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 that 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; where imaging data sets are acquired using conventional two-dimensional scans of the object in both a supine and prone orientation, and correspondence between the respective data sets is determined to permit jumping from one visualization orientation to the other while remaining at the same virtual location within the organ.
