Patent number: 7899226Abstract: A system to navigate an image-guided object traveling in an area of interest of an imaged subject in relation to an acquired image of the imaged subject as created by an imaging system is provided. The system includes a navigation system to track movement of the object in the imaged subject in spatial relation to a navigation coordinate system, and a controller. The controller is operable in detecting an image of the object in the at least one image of the imaged subject, calculating a spatial relation between the location of the image of the object and a tracked location of the object, and modifying the spatial relation of the image coordinate system relative to the navigation coordinate system so as to reduce the difference between the location of the image of the object and the tracked location of the object by the navigation system.Type: GrantFiled: April 3, 2007Date of Patent: March 1, 2011Assignee: General Electric CompanyInventors: Jeremie Pescatore, Michel F. Grimaud, Gerald L. Beauregard

Patent number: 7835779Abstract: The present invention provides an electromagnetic tracking system that includes a field generator and a field sensor arranged to generate and detect, respectively, an electromagnetic field. Both the transmitter and receiver coils are connected to signal conditioning and processing circuitry to provide outputs indicative of the coil signals. A processor operates on the signals to determine the coordinates of the sensing assembly relative to the generator assembly. The signal processor produces ratiometric outputs, and applies a mutual inductance model to solve for position/orientation coordinates. In some embodiments, a disturber in the form of a conductive ring or a sheath is disposed about an interfering piece of equipment to moderate and standardize disturbances due to eddy currents.Type: GrantFiled: May 10, 2006Date of Patent: November 16, 2010Assignee: GE Medical Systems Global Technology Company LLCInventors: Peter T. Anderson, Gerald L. Beauregard, Christopher D. Cherry
