20080287778 | IMAGING AND NAVIGATION SYSTEM - An imaging and navigation system is disclosed herein. The imaging and navigation system includes a computer and an ultrasonic imaging device disposed at least partially within an ultrasound catheter. The ultrasonic imaging device is connected to the computer and is adapted to obtain a generally real time three-dimensional image. The imaging and navigation system also includes a tracking system connected to the computer. The tracking system is adapted to estimate a position of a medical instrument. The imaging and navigation system also includes a display connected to the computer. The display is adapted to depict the generally real time three-dimensional image from the ultrasonic imaging device and to graphically convey the estimated position of the medical instrument. | 11-20-2008 |

20100137705 | Surgical Navigation System with Magnetoresistance Sensors - A surgical navigation system having one or more magnetoresistance sensors, where the sensors have the noise and dynamic range appropriate for electromagnetic position and orientation tracking. The surgical navigation system comprising at least one magnetoresistance reference sensor rigidly attached to an anatomical reference of a patient, at least one magnetoresistance sensor attached to at least one device, and at least one processor for determining the position and orientation of the at least one device. | 06-03-2010 |
20100138183 | Surgical Navigation Enabled Imaging Table Environment - A system for integrating radiolucent tracking sensors in a medical table, table mat, or surgical drape of a surgical navigation system, allowing the surgical navigation system to be less obtrusive in a surgery environment. A plurality of radiolucent magnetoresistance sensors are integrated into a table, table mat, or surgical draping of a surgical navigation system for improving surgical navigation workflow and eliminating image artifacts from intraoperative images. The plurality of radiolucent magnetoresistance sensors may be located within a table or adjacent to a table surface. | 06-03-2010 |
20100249571 | SURGICAL NAVIGATION SYSTEM WITH WIRELESS MAGNETORESISTANCE TRACKING SENSORS - A surgical navigation system having one or more wireless magnetoresistance sensors, where the sensors have the noise and dynamic range appropriate for position and orientation tracking. The surgical navigation system comprising at least one wireless magnetoresistance reference sensor rigidly attached to at least one anatomical reference of a patient, at least one wireless magnetoresistance sensor attached to at least one device, and at least one processor for determining the position and orientation of the at least one device. | 09-30-2010 |
20100305427 | LONG-RANGE PLANAR SENSOR ARRAY FOR USE IN A SURGICAL NAVIGATION SYSTEM - A planar sensor array for use in a surgical navigation system comprising at least one substrate and at two layers of a plurality of planar sensor coils formed on or within the at least one insulating substrate. The planar sensor array may be an electromagnetic planar transmitter coil array or an electromagnetic planar receiver coil array that includes at two layers of a plurality of planar electromagnetic transmitter or receiver spiral-shaped coils formed on or within the at least one substrate. The surgical navigation system includes the use of at least one magnetoresistance reference sensor attached to a fixed object; at least one magnetoresistance sensor attached to an object being tracked; and a planar sensor coil array communicating with the at least one magnetoresistance reference sensor and the at least one magnetoresistance sensor to determine the position and orientation of the object being tracked. | 12-02-2010 |
20110152676 | INTRA-OPERATIVE REGISTRATION FOR NAVIGATED SURGICAL PROCEDURES - A navigation system for use during a surgical procedure is provided. The navigation system is configured to use electromagnetic tracking data produced by electromagnetic tracking devices and 2D image data produced by a fluoroscope to intra-operatively register 2D images of a patient to a pre-operative 3D image of the patient. In some implementations, a surgeon may be able to perform an interventional or surgical procedure guided by the navigation system. | 06-23-2011 |
