Summary A novel method to investigate the gastro-intestinal activity by means of a superconducting instrumentation based on SQUID sensors developed for biomagnetic measurements is presented. The magnetic field generated by a small marker ingested by the subject is measured over the abdomen. The localization of the marker,i.e. a magnetic dipole, is carried out by means of a standard algorithm used in biomagnetic studies. In this way it is possible to noninvasively study the activity of the gastro-intestinal system. This new approach may lead to important clinical applications.
