| 摘 要： | 提出了一种基于物理模型的超声多普勒信号模拟方法，它可以适用于分层，脉动，非均匀的血流情况，这种方法直接以血流情况，仪器参数等作为输入，产生同时反映正反向血流信息的解析多普勒信号。实验,和这个方法生成的信号能够较好地模拟实际多普勒信号的各种特性，因此这个方法是有效而可行的。

| Abstract: | A computer method
based on physical models for generating Doppler ultrasound signals from laminar, pulsatile,
nonuniform flow is presented. The Doppler in phase and quadrature signals can be simulated
when the flow characteristics and the instrument parameters are given as inputs. Experiments
results show that the model can generate signals with characteristics similar to those of the real
Doppler signals. Thus this method is effective. |
