Electromagnetically Navigated Endoscopy: Evolutionary Optimization Methods

Endoscopy is one of key steps of diagnostic surgery. Using electromagnetic trackers (EMT) to navigate an endoscope are increasingly introduced in endoscopic interventions. Unfortunately, the bad tracking accuracy of directly using EMT sensor measurements, which may be heavily deteriorated by patient respiratory motion and magnetic field distortion of EMT, limits its clinical applications. Beyond integrating optical tracking systems to compensate the accuracy of EMT, evolutionary optimization methods are promising without additional setups during navigated endoscopy. More interestingly, evolutionary optimization enables EMT to adapt itself robust to uncertainties (e.g., breathing motion or problematic video images) that are occurred in endoscopic examinations.
