Use of a 3-D Wireless Power Transfer Technique as a Method for Capsule Localization

Capsule endoscopy has been heralded as a technological milestone in the diagnosis and therapeutics of gastrointestinal (GI) pathologies. The location position capsule within GI tract are important information for subsequent surgical intervention or local drug delivery. Accurate is therefore required during endoscopy. Although radio frequency (RF)-based, magnetic tracking video localization have investigated past, complexity those systems potential inaccuracy data necessitate scope further research. This article proposes dual use wireless power transfer (WPT) configuration method to enable determination an endoscopic capsule. Measurements conducted on homogeneous agar-based liquid phantom predict maximum error 12% between calculated measured trajectories working volume 100 mm×100 mm.
