DATA-PROCESSING TECHNIQUES FOR SERIAL EIT SPECTROSCOPY IMAGES - A REVIEW OF SOME PRELIMINARY-RESULTS

Multifrequency EIT imaging should allow specific organs within the bod y to be identified by their impedance spectrum, and the use of paramet ric imaging should lead to a much greater freedom from movement artefa cts. This will make EIT more attractive as a monitoring technique, but the data rate will require automated processing of the images. The ap plication of dynamic regions of interest, generated on a frame by fram e basis, is described, with examples from the imaging of neonatal lung s and adult stomach. The lung can be objectively identified on a singl e frame from the f(RSC), SC and RC images, but the stomach could only be identified on the dynamic images.
