Rh. Smallwood et Ar. Hampshire, DATA-PROCESSING TECHNIQUES FOR SERIAL EIT SPECTROSCOPY IMAGES - A REVIEW OF SOME PRELIMINARY-RESULTS, Physiological measurement, 16, 1995, pp. 129-142
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.
