Wireless Electromagnetic Tracking System for Wireless Capsule Endoscope

Electromagnetic tracking (EMT) is widely used in image-guided surgical procedures, enabling precise tracking of the position and orientation of medical instruments. However, the traditional wired EMT system needs wires to be led out from the transmitting side to the receiving side, rendering it unsuitable for tracking in vivo biomedical implants. This study proposes a 6-DoF wireless tracking hybrid method based on the EMT and inertial measurement unit.
