Physiological Influences on Tissue Electrical Properties in Situ.
Abstract
Measurements of biological tissue dielectric property changes in response to physiological changes may be measured using a small in-situ probe over a wide frequency range. This report describes dielectric property measurements made primarily at 2.45 GHz using a canine brain model and a canine kidney model under varying conditions of perfusion. Experiments during the final year of this program seemed to show some correlation between renal tissue dielectric properties and total renal blood flow under the conditions of pressure-induced blood flow autoregulation, renal nerve stimulation, and pharmacologically-induced properties. Originator supplied keywords include: Dielectric properties; Measurements of dielectric properties in renal tissue; in-situ dielectric property measurement probe; physiological influences on tissue dielectric properties; renal blood flow autoregulation.
