Experimental Compensation for Difference between Small‐Particle Aggregates and Substitute Large Particles in Ultrasonic Spectroscopy

Abstract

SUMMARY The measurement of blood viscosity in the human body is very important for preventing diabetes mellitus. The blood viscosity is strongly correlated with aggregation of red blood cells. Some noninvasive methods for estimating the blood viscosity based on ultrasonic spectroscopy have been proposed. In these studies, substitution experiments using particles with a large diameter have been performed in general because control of the aggregation size is very difficult. This study is aimed at assessing the validity of the substitution experiments and proposing a compensation technique for use in the substitution experiments.
