Paper Abstract

In this study we present a new laser Doppler velocimeter (LDV) with an optical fiber to measure blood flow velocities accurately. After fundamental experiments to evaluate the accuracy and performances of this LDV in the blood velocimetry, blood flow velocity profiles in coronary arteries were evaluated in mongrel dogs. It was shown that this LDV is a feasible and useful to measure the dynamic blood flow velocity in coronary arteries. Finally, our LDV was remodeled to a catheter type for clinical application.
