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.
为评估冠状动脉中时相性血流的详细特征，研制了一种使用光纤的高分辨率激光多普勒测速仪。在麻醉开胸犬的左旋支冠状动脉近端（内径0.27±0.05 cm）和远端（内径0.09±0.02 cm）测量局部血流速度。比较了近端和远端血管中心轴区域的速度波形以及血管腔的速度分布。
