Hanyang University Team Develops AI Technology for Precise Real-Time Tracking of Capsule Endoscopes

Researchers at Hanyang University have achieved a significant breakthrough in medical diagnostics with the development of an AI-powered system for precisely tracking wireless capsule endoscopes within the human body. This innovative technology, developed by Professor Yu Hyung-seok and his team at the university's Radio Research Center, promises to revolutionize how gastrointestinal conditions are diagnosed and treated.

The new system utilizes artificial intelligence combined with wearable antenna technology to overcome a critical limitation of current capsule endoscopes. While these devices offer a non-invasive way to visualize the digestive tract, they passively move through the body, making it difficult for medical professionals to determine the exact location of any detected abnormalities. The Hanyang University team's solution addresses this by collecting signal strength data from a capsule's transmitter and four wearable receivers, then analyzing this data with AI machine learning algorithms.

This research has elevated the accuracy of wireless capsule endoscope localization to a world-class level by integrating radio wave technology and artificial intelligence.

What sets this research apart is its rigorous testing in a complex, multi-layered 'phantom' environment that closely mimics human tissues, including skin, fat, muscle, and gastrointestinal fluid. Previous studies often relied on simpler saline solutions or computer simulations, failing to accurately reflect the challenging radio wave conditions within the actual human body. By successfully mapping 3,300 signal strength data points to precise 3D coordinates, the system demonstrated remarkable accuracy, achieving a root mean square error (RMSE) of just 1.69 cm for 3D positioning and an astonishing 0.39 cm for tracking movement.

This advancement holds immense potential for improving patient care. By accurately identifying the location of lesions, doctors can develop more precise diagnostic and treatment plans. Furthermore, the technology opens doors for future applications in targeted drug delivery, real-time lesion tracking, and remote control of internal medical devices, heralding a new era of digital healthcare.

Hanyang University's Radio Research Center precisely interprets the radio wave environment between internal human bodies and wearable devices, and continuously pursues research to connect this to medical diagnosis and treatment technologies. We will continue to lead precision medical innovation through AI-based bioelectronic and next-generation wireless medical device technologies.
