Abstract
The Doppler shift of ultrasound, scattered from moving elements within a stream of blood, is related to the velocity of blood flow. A flowmeter based on this principle has been constructed and was used to record blood flow through intact vessels in dogs.
摘要
从血流中的移动成分散射回来的超声的多普勒频移与血流速度相关。基于这一原理构建了一种流量计，并用于记录狗完整血管中的血流情况。
