Estimation of dielectric parameters of red blood cell membranes by microwave dielectrometry: early diagnostics and treatment control for ischemic stroke patients

Abstract

Stroke is one of the leading causes of morbidity and mortality in the world. In vitro measurement of the dielectric parameters of blood and their dynamical changes makes it possible to evaluate the severity of the stroke ischemia and success of the prescribed therapy, as well as identify patients with a probable unfavourable prognosis. In this study the dielectric parameters of suspensions of the red blood cells (RBC) and their ghosts taken from the blood samples of the patients with ischemic stroke have been determined in vitro by the ultra high frequency (UHF) dielectrometry at the operating frequency f = 9.2 GHz.
