Abstract

Magnetogastrograms (MGGs) using a superconducting quantum interference device (SQUID) gradiometer provides excellent temporal and spatial resolution, and are effective non-invasive tool for detecting functional disorder. It is reported that slow motility waves originate high on the greater curvature of the stomach, an area that acts as a pacemaker, which coordinate contractions of the gastric smooth muscle [1, 2]. The gastric electrical activity produces a weak magnetic field. The purpose of the present study was to assess the magnetic field due to gastric electrical activity and to localize the gastric pacemaker site using a 64-channel SQUID system.
