摘要
针对超声相控阵成像中的波束合成问题,研究了现有的波束成形技术,并对比了标准相控聚焦和动态深度聚焦的差异,据此设计了一种超声相控阵波束成形器,实现了实时波束成形、动态深度聚焦、幅度加权等功能,具有实时性强、延迟分辨率高、控制灵活方便等特点。
The technology of ultrasonic phased array beam forming is studied, and the differences between the standard phased focusing and the dynamic depth focusing are compared. Then, an ultrasonic phased array beam former is designed, and the functions of real-time beam forming, dynamic depth focusing, amplitude weighting are realized.
