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.
