Exploration of the Transverse Doppler Effect

根据经典的流量测量理论， 多普勒超声，人们只能估计这一部分 在超声波的方向上 梁 PI已经发现， 垂直于超声波的方向也可以通过 适当分析反射光谱 信号了 这是一个扩展这一新发现的提议 湍流和设计传感器， 确定层流或层流下的血流量 湍流条件 拟议的研究具有 极大地提高我们衡量 无创性血流。

According to the classical theory of measuring flow by Doppler ultrasound, one can estimate only that component of the flow that is in the direction of the ultrasound beam. The PI has discovered that flow that is perpendicular to the ultrasound can also be measured by appropriate analysis of the spectrum of the reflected signal. This is a proposal to extend this novel finding to turbulent flow and to design transducers that allow determination of blood flow under either laminar or turbulent flow conditions. The proposed research has the potential of greatly improving our ability to measure blood flow noninvasively.
