摘要
计算机仿真超声彩色血流图像,可以为各种超声彩色血流图像处理方法的性能比较提供有效的信号源.在仿真某一时刻静态超声彩色血流图像的基础上,根据给定的一个心动周期的最大血流速度曲线,计算出血管内的血流速度分布随时间的变化,对一个心动周期划分24时相,仿真出动态超声彩色血流图像.
Computer simulated ultrasound color flow images could be used as efficient signal sources for the evaluation of various ultrasound flow image processing methods. Base on the simulation of a single frame of static ultrasound color flow image, a method to simulate the dynamic ultrasound color flow image is proposed. With the given maximum velocity curve over a cardiac cycle, the variation of the blood flow velocify distribution is calculated. The dynamic ultrasound color flow image is generated by combining 24 frames of static color flow image, each of which corresponds to a different time phase of a cardiac cycle.
