Analysis of Magnetic Marker Localization Method for Non-invasive Detecting Capsule with Batteries in GI Tract

摘要：

The paper discusses the magnetic marker localization method utilizing four tri-axis magnetoresistive sensors for non-invasive detecting capsule in GI tract. Because two silver oxide button batteries in capsule, which outer shell is made from high permeable Co-Ni-Fe alloy, supply power for all modules of the capsule, and the alloy is strong permeable, the batteries will affect magnetic localization precise. Authors employ magnetic dipole theory and magnetic field superposition principle, deducts math model as considering the batteries affects. Experiment shows the calculation model is feasible.
