Abstract

Our laser Doppler velocimeter (LDV) with an optical fiber is a powerful tool for the measurement of both coronary artery and vein flow velocities because of its excellent accessibility to the coronary vessels of a moving heart. In this paper, we briefly describe the optical arrangement of the LDV and then introduce some results of measurements of the blood velocity patterns of epicardial large coronary vessels, and epicardial small arteries and veins obtained by two different routes of access of fiber probe. We also touch upon the dual-core-fiber system which is probably promising as a Doppler catheter for clinical use
