Patent number: 6612980Abstract: 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.Type: GrantFiled: June 5, 2001Date of Patent: September 2, 2003Assignee: Medical Media SystemsInventors: David T.

Patent number: 6261226Abstract: A multiple view endoscope provides “on command” images of a plurality of different fields of view surrounding the distal end of the endoscope without having to move the endoscope from an initially established position in order to access the different fields of view. In one embodiment, a CCD element comprising a plurality of CCD cells forms a circumferential band about the distal portion of the endoscope. In another embodiment, the plurality of CCD cells covers substantially all of the outer side wall of the shaft adjacent to the distal end. In both embodiments, a processing device functions to either use the outputs from all the CCD cells to generate a display image or use the outputs from only selected ones of the CCD cells to generate a display image of a selected portion of the entire image captured by the CCD element.Type: GrantFiled: September 1, 1998Date of Patent: July 17, 2001Assignee: Medical Media SystemsInventors: Michael A.
