摘要
根据超声成像系统的发展进程,阐述四种典型的声束形成器。并从性能、集成度以及成本等多个角度展开对比分析,总 结出模拟声束形成器和三种数字声束形成器的各自特点,指出未来声束形成器的发展方向。
In this paper, four typical beamformers are explained according to the development process of ultrasound imaging systems. Comparison and analysis are made from several aspects, such as performance, integration, cost, and so on Furthermore, characteristics of an analog and three digital beamformers are respectively summarized. At last, the development direction of beamformers is pointed out.
