Abstract:
Preliminary work has been carried out using the Sheffield mark II real time EIT system, looking for changes in conductivity which occur in the stomach and oesophagus following a swallow of a small volume of either a conducting or a non-conducting liquid. This has been done using three different configurations: a conventional transverse array placed around the thorax, a rosette array on the abdomen, and a rosette array placed on the back. Results show a significant difference between the two liquids, which can be detected equally well by the three electrode configurations.
