Abstract
An improved anatomical visualization system which is adapted to augment a standard video endoscopic system with a coordinated computer model visualization system so as to enhance a physician's understanding of the patient's interior anatomical structure A database defining a 3-D computer model comprises at least a first software object corresponding to the anatomical structure. A second software object having a surface is placed in registration with the first software object such that they coexist in a single coordinate system. A movable sensor, such as an endoscope, acquires a real-time video image which is texture mapped onto the surface of the second software object. A processing device is provided to generate an image from the first and second registered software objects taken from any specified point of view relative to the single coordinate system.
