Before an image-guided surgery, a patient will have a CT scan performed to help inform the physician that will be operating on the area of interest. During the surgical procedure, a magnetically tracked probe is used to correlate the physical location within the patient and the aforementioned CT scan. Magnetic tracking systems incur high costs and cannot be used in patients with pacemakers due to electronic interference.

To mitigate these issues, researchers at the University of California, Irvine developed a tracking system that utilizes a low-cost gyroscope/accelerometer positioning sensor and reference frame. This solution accomplishes the same tasks as its magnetic counterparts at a fraction of the cost and can be used on patients with pacemakers due to the lack of magnetic fields.

Advantages:

  • Cost-efficient: Use of a low-cost gyroscope/accelerometer significantly reduces costs for real-time visualization of intraoperative surgical positioning.
  • Compatibility: The lack of magnetic fields used in this tracking systems allows for this invention to be used in patients with pacemakers without having to worry about electrical interference.

Potential Applications:

  • Intraoperative 3-D positioning sensor to enable CT image guided surgery.
