采用光纤的高分辨率激光多普勒测速仪用于评估冠状动脉相血流量的详细特征。在麻醉开胸犬左旋冠状动脉近端（0.27±0.05 cm i.d）和远端（0.09±0.02 cm i.d）测量局部血流速度。比较近端和远端血管中轴部的速度波形和血管腔的速度分布。
A high resolution laser Doppler velocimeter using an optical fiber was developed to evaluate detailed characteristics of phasic blood flow in the coronary artery. Local blood flow velocities were measured in the proximal (0.27 ± 0.05 cm i.d.) and the distal portion (0.09 ± 0.02 cm i.d.) of the left circumflex coronary artery of anesthetized, open-chest dogs. The velocity waveform in the central axial region of the vessel and the velocity profile across the vascular lumen were compared in the proximal and the distal portions.
