Various expressions of the speed of flow of blood in arteries are discussed, such as instantaneous speed, integral speed, pulse wave speed (phase speed) and velocity of a moving front. The flow profile of the abdominal aorta was obtained by cine-densitometry, bearing in mind the above considerations, and the densitometric curves have been analysed. Differences of the flow velocities in different persons have been interpreted as a result of these theoretical considerations. The effects of the point of measurement, the distance over which the measurement was carried out and the pulse wave length on velocity were examined. In order to obtain a median blood stream velocity by angio-cine-densitometry, repeated injections of small volumes of contrast medium (random sampling method) are recommended.
本文讨论了动脉中血流速度的各种表达方式，如瞬时速度、积分速度、脉搏波速度（相速度）和移动前沿速度。考虑到上述因素，通过电影密度计法获得了腹主动脉的血流剖面，并对密度计曲线进行了分析。基于这些理论考虑，对不同个体血流速度的差异进行了解释。研究了测量点、测量距离和脉搏波长对速度的影响。为了通过血管电影密度计法获得血流速度中位数，建议重复注射小剂量造影剂（随机抽样法）。
