Blood volume flow estimation remains an important task for the functional evaluation of internal organs. In vitro and in vivo flow estimation has been carried out using Flash Echo Imaging in harmonic mode after the administration of microbubble-based ultrasound contrast agents. The in vitro flow volume rate correlated with the constant replenishment level but less so with the video intensity decay rate. The in vivo volume flow rates obtained in four dogs agreed well with CVI-Q (time domain correlation) based flow measurement. Our experimental results indicate that the volume flow rate can be accurately estimated in vitro and in vivo using harmonic Flash Echo imaging.
血容量流量估计仍然是评估内部器官功能的一项重要任务。在注射基于微泡的超声造影剂后，已使用谐波模式下的快速回波成像进行了体外和体内流量估计。体外流量速率与恒定的补充水平相关，但与视频强度衰减速率的相关性较小。在四只狗身上获得的体内体积流量速率与基于CVI-Q（时域相关性）的流量测量结果非常吻合。我们的实验结果表明，使用谐波快速回波成像可以在体外和体内准确估计体积流量速率。
