Summary:Disclosed are a VTI measuring device and a measuring method. The method comprising: controlling an ultrasonic probe (110) to emit ultrasonic waves at tissue (190) to be measured; receiving an ultrasonic echo returned from the tissue to be measured; finding, according to the ultrasonic echo, a target sampling position having the smallest hemodynamic information interference (305). A VTI at the target sampling position is then calculated. The calculated VTI is the least affected by the friction of the blood vessel wall and can best reflect the heart's pumping ability and cardiac output. 公开了一种VTI测量装置及测量方法，控制超声探头（110）向被测组织（190）发射超声波，接收由被测组织返回的超声波的回波，根据超声波的回波找到血流动力信息受干扰最小的目标采样位置（305），然后计算该目标采样位置处的VTI。计算出的VTI受到的血管壁摩擦力的影响最小，最能反映心脏的泵血能力和心输出量。
