    Abstract: A method of estimating the volume flow in a vessel utilising ultrasound techniques comprising the steps of imaging the vessel utilising an ultrasonic transducer array so as to produce fluid velocity information for the vessel, the plane formed by the beams emitted by the transducers having a direction which is offset from an axis of the vessel such that the beam plane forms an elliptical section within the vessel; and utilising the velocity information for points within the vessel and the elliptical section to calculate a mean velocity for the fluid flow through the elliptical section.

    Abstract translation: 一种利用超声波技术估计容器中的体积流量的方法，该方法包括以下步骤：利用超声波换能器阵列对血管进行成像，从而产生血管的流体速度信息，由换能器发射的光束形成的平面的方向为 偏离容器的轴线，使得光束平面在容器内形成椭圆形截面; 并利用容器内的点和椭圆部分的速度信息来计算流过椭圆部分的流体的平均速度。
