20080204000 | UNIVERSAL INSTRUMENT CALIBRATION SYSTEM AND METHOD OF USE - Certain embodiments of the present invention provide systems and methods for electromagnetic calibration of an instrument. Certain embodiments provide an electromagnetic instrument calibration system including electromagnetic receiver electronics for receiving electromagnetic field information from an electromagnetic transmitter. The system also includes a calibration mount configured to position the electromagnetic receiver electronics stationary with respect to the calibration mount for calibrating an instrument having an electromagnetic transmitter using the calibration mount and the electromagnetic receiver electronics. Certain embodiments provide a method for calibration of an instrument based on electromagnetic field information including providing a calibration mount accommodating a plurality of instruments in a known position and orientation and having electromagnetic calibration electronics positioned with respect to the calibration mount; receiving electromagnetic field information for an instrument with respect to a known position of the calibration mount and electromagnetic calibration electronics; and calibrating at least a portion of the instrument. | 08-28-2008 |
20080300481 | Dynamic reference method and system for use with surgical procedures - A substrate configured for placement on an internal organ or tissue is provided. In certain embodiments, the substrate conforms to and moves with the internal organ or tissue. Three or more sensor elements are integrated on the substrate. In one implementation, the substrate and associated sensor elements provide dynamic referencing of the internal organ or tissue after registration of the sensor data with images and/or volumetric representations of the internal organ or tissue. | 12-04-2008 |
20090088629 | Dynamic reference method and system for interventional procedures - An interventional device configured for placement in or near an internal organ or tissue is provided. The interventional device includes a reference portion having three or more sensor elements. In one implementation, the interventional device and associated sensor elements provide dynamic referencing of the internal organ, tissue or associated vasculature after registration of the sensor data with images and/or volumetric representations of the internal organ or tissue. | 04-02-2009 |
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 |
20110319751 | DYNAMIC REFERENCE METHOD AND SYSTEM FOR USE WITH SURGICAL PROCEDURES - A substrate configured for placement on an internal organ or internal tissue is provided. In certain embodiments, the substrate conforms to and moves with the internal organ or internal tissue. Three or more sensor elements are integrated on the substrate. In one implementation, the substrate and associated sensor elements provide dynamic referencing of the internal organ or internal tissue after registration of the sensor data with images and/or volumetric representations of the internal organ or internal tissue. | 12-29-2011 |
20120165657 | HYBRID TRACKING SYSTEM UTILIZING COMBINED LED AND MAGNETORESISTANCE SENSORS - A hybrid tracking system utilizing at least one combined light emitting diode (LED) and magnetoresistance sensor. The hybrid tracking system includes optical tracking technology and electromagnetic (EM) tracking technology with at least one combined LED and magnetoresistance reference sensor attached to a fixed object, at least one combined LED and magnetoresistance sensor attached to an object being tracked, and a processor coupled to the at least one combined LED and magnetoresistance reference sensor and the at least one combined LED and magnetoresistance sensor for processing signals from the at least one combined LED and magnetoresistance reference sensor and the at least one combined LED and magnetoresistance sensor. The combined LED and magnetoresistance sensor includes at least one magnetoresistance sensor and at least one LED that are integrated into a single package. | 06-28-2012 |
20130079628 | DYNAMIC REFERENCE METHOD AND SYSTEM FOR INTERVENTIONAL PROCEDURES - An interventional device configured for placement in or near an internal organ or tissue is provided. The interventional device includes a reference portion having three or more sensor elements. In one implementation, the interventional device and associated sensor elements provide dynamic referencing of the internal organ, tissue or associated vasculature after registration of the sensor data with images and/or volumetric representations of the internal organ or tissue. | 03-28-2013 |
