A vector SQUID gradiometer (Conductus Instruments, Inc., San Diego, CA) was used to measure magnetic fields associated with bioelectric sources in the stomach and small intestine of normal, healthy, human volunteers. These measurements are an extension to previous work [1,2,3] in which a single component of the magnetic field was measured. Magnetic recordings associated with gastrointestinal current sources, known as the Magneto-ENteroGram (MENG), contain frequency information about a specific type of activity known as the Basic Electrical Rhythm (BER). In normal subjects, the BER frequency of the stomach is approximately 3 cycles per minute (cpm), and varies in the small intestine from 12 cpm in the duodenum to 8 cpm in the terminal ileum. Certain disease conditions can change BER frequency [4], and it is therefore of interest to localize sources of particular frequencies. One of the advantages of using a vector instrument to measure these magnetic fields is that we are sensitive to current sources of all geometric orientations in the abdomen. One of the challenges of using a single channel vector instrument is to decouple the contributions from multiple sources in the magnetic recordings. Since the multiple current sources in the abdomen are of varying frequency, are spatially distributed, and are generally of different orientations, it follows that at a given location, the vector magnetic fields from each current source should point in different directions. The purpose of this preliminary study is to measure the vector MENG in order to examine the possibility that using all components of the magnetic field could be more suitable than using only a single component for localizing current sources in the gastrointestinal tract of humans.
