Abstract
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.
Claims31
A surgical navigation system comprising:
- at least one wireless magnetoresistance reference sensor rigidly attached to an 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.
A surgical navigation system comprising:
- at least one wireless magnetoresistance sensor attached to at least one device;
- a planar sensor array positioned on a table supporting a patient undergoing a medical procedure;
- and
- at least one processor for determining the position and orientation of the at least one device.
An integrated circuit device for use in a surgical navigation system comprising:
- a magnetoresistance sensor;
- and
- additional circuitry coupled to the magnetoresistance sensor;
- wherein the magnetoresistance sensor and the additional circuitry coupled to the magnetoresistance sensor operate wirelessly.
