Hybrid Electromagnetic and Optical Tracking System for lntraoperative Imaging and Robotics Surgery

Tracking system in neurosurgery aims to enhance intraoperative imaging and robotic surgery in Hong Kong. The development of medical technologies has significantly improved surgical precision, with tracking systems playing a pivotal role. The surgical instrument tracking system market is projected to reach $600 million by 2023, growing at a CAGR of 18.6%. This robust growth is expected to continue, with the market size forecasted to reach approximately $1 .2 billion by 2027. Market leaders are investing in advanced tracking technologies. lntraoperative imaging techniques like fluorescence imaging, iMRI, and iCT are increasingly used, aided by tracking systems for precise instrument guidance. Robotic surgery is emerging in neurosurgery, enhancing accuracy and control. Optical and electromagnetic tracking systems are commonly employed in this context, each with its advantages and limitations. Optical tracking ·systems offer high accuracy but require a clear line of sight. Electromagnetic systems don't rely on Hne-ofsight but may be affected by ferromagnetic objects and have accuracy limitations.The proposed study aims to construct an enhanced hybrid tracking system that combines electromagnetic and optical tracking, employing a sensor fusion algorithm. The goal is to improve data rate and accuracy for intraoperative imaging and robotic surgery. The study will be evaluated using a patient-specific phantom, and the tracking results will be visualized through a custom 30 simulation platform. This system will be integrated with AR technology for further testing in a clinical trial to assess its effectiveness in a real surgical environment. This research aims to advance neurosurgery techniques, enhance precision, and improve patient outcomes.
