Determination of volume of arterial blood flow by an ultrasonic device.
This paper describes the results of a reevaluation of the reliability of a newly developed ultrasonic volume flow meter which was developed by Yoshimura and his co-workers (1978). Measurements of volume blood flow (cc/sec) by this new technique were compared with measurement by the electromagnet flow meter. Experiments were performed with an in vitro model as well as with physiological pulsatile flow in an animal model. Results of the study indicated a high degree of correlation between values measured by both techniques with a correlation coefficient of 0.99 I believe that this is an important technical development in the field of noninvasive quantitative determination of blood flow.
