Physiological Influences on Tissue Electrical Properties In Situ.

Abstract

The overall objectives of this research investigation are to further develop and extend the capabilities of the recently-developed in-vivo probe measurement technique and to use this technique to study the possible effects of induced physiological changes on tissue dielectric properties. During the third year of the program, the research investigations performed included (1) dielectric measurement of renal tissue under controlled perfusion conditions, both in-vitro and in-vivo, (2) preliminary investigation of the influence on these properties of alpha-blocking drugs added to the perfusate, (3) characterization of renal pressure/flow relationship, (4) design and development of hardware for a fully automated data acquisition and processing system, and (5) development of software for statistical analysis of experimental results. In addition to these investigations, a 3/4-gamma monopole antenna over a ground plane designed for underwater operation was developed for use by Army personnel at the Walter Reed Army Institute of Research. Originator supplied keywords include: Antemortem/postmortem studies, Renal blood flow, and Electromagnetic energy.
