A novel optical tracking system enables seamless transfer of registration data, enhancing surgical procedures near MRI scanners. This system allows unrestricted instrument use and intraoperative imaging for improved patient care.

Area of Science:

  • Medical Imaging
  • Surgical Navigation
  • Biomedical Engineering

Background:

  • Interventional procedures near MRI scanners offer expanded operational capabilities.
  • Current optical tracking systems require methods for transferring registration data between locations.
  • Intraoperative imaging and unrestricted surgical instrument use are crucial for optimal outcomes.

Purpose of the Study:

  • To develop and validate a method for transferring optical navigator registration data between two locations.
  • To enable unrestricted use of surgical instruments outside the magnetic resonance (MR) scanner.
  • To facilitate intraoperative imaging during procedures in close proximity to an MR scanner.

Main Methods:

  • Development of a novel optical tracking system.
