Abstract

Biomagnetic measurement using superconducting quantum interference device (SQUID) is an effective non-invasive tool for detecting gastric function. In the present study, the weak magnetic field originating from gastric mechanical motility was detected using a newly developed high temperature (−196°C) SQUID system by liquid nitrogen.
