Magnetic Tracking System
US Patent:
6774624, Aug 10, 2004
Filed:
Mar 27, 2002
Appl. No.:
10/108197
Inventors:
Peter T. Anderson - Andover MA

Assignee:
GE Medical Systems Global Technology Company, LLC - Waukesha WI
International Classification:
G01B 714
US Classification:
32420717, 32420722, 324247, 600424, 702150
Abstract:
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.

Electromagnetic Tracking Using A Discretized Numerical Field Model
US Patent:
7532997, May 12, 2009
Filed:
Apr 17, 2006
Appl. No.:
11/379024
Inventors:
Dun Alex Li - Salem NH, US
Peter Traneus Anderson - Andover MA, US
Gerald Lee Beauregard - Stratham NH, US
Peter Traneus Anderson - Andover MA, US

Assignee:
General Electric Company - Schenectady NY
International Classification:
G01C 17/00
US Classification:
702150, 32420717, 702134, 702152
Abstract:
A method for electromagnetic tracking the position and orientation of an object using a discretized numerical field model, rather than the conventional analytical dipole model. The method including the steps of determining a discretized numerical field model associated with a particular distortion source; acquiring mutual inductance signals between electromagnetic sensors and the particular distortion source, the sensors being rigidly attached to a tracked object; estimating an initial position for the tracked object in the presence of the particular distortion source; refining the estimated position of the tracked object; and estimating an orientation of the tracked object.

A61B 6/00
G01N 23/04
US Classification:
382128, 378 4, 378 62
Abstract:
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.
