摘要:
Certain embodiments of the present invention provide a method for correlating data including: receiving from a tracking subsystem a first data set including a tracked position of an object; receiving from an imaging subsystem a second data set including an image of the object; and comparing automatically at least a portion of the first data set with at least a portion of the second data based at least in part on the tracked position of the object and the image of the object. In an embodiment, the comparing automatically the first data set with the second data set is performable in real-time. In an embodiment, the method further includes registering the first data set with the second data set. In an embodiment, the tracking subsystem tracks the object electromagnetically, at least in part. In an embodiment, the imaging subsystem includes an x-ray imaging subsystem. In an embodiment, the first data set is generatable by the tracking subsystem substantially in real-time. In an embodiment, the method further includes determining an offset between at least a portion of the first data set and at least a portion of the second data set. In an embodiment, the method further includes performing an adjustment based at least in part on the offset on at least one of: the tracking subsystem, the imaging subsystem, and a data processing subsystem.

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.

A system having unified diagnostics where an electrical energy storage device may supply an actuator. Various techniques may be used to determine energy storage capacity and actuator current usage. Measured storage capacity and actuator current may indicate the health of the energy storage device and the actuator, respectively. Also, operation of a service switch for the actuator may be checked relative to its state.

In one embodiment, a method of detecting a distortion is provided. The method comprises steps of identifying a change in transmitter gain for a first transmitter coil, identifying a change in transmitter gain for a second transmitter coil, comparing the change in transmitter gain for the first transmitter coil with the change in transmitter gain for the second transmitter coil and identifying a first condition upon determining that the change in transmitter gain for the first transmitter coil is different from the change in transmitter gain for the second transmitter coil.
