| 摘 要： | 医用超声诊断设备中存在两种声束形成技术。近年来在少数几个高档设备中使用了数字声束形成技术。正交分解是获得复包络信号的幅度和相位的关键，而数字延迟是数字电子聚焦所必须的。文中介绍了数字多声束形成的原理及应用。 |
| 关 键 词： | 数字声束形成；多声束形成；超声成像；数字延迟 |

| Abstract: | There are two beamforming techniques in the medical ultrasound diagnostic equipment. Thedigital beamforming technique is used by few advanced equipment in recent years. The quadraturedecomposition is the key to obtain the amplitude and phase of complex envelope. The digital delay techniqueis necessary for digital electronic focusing. The principle and application of digital multi- beamformingtechnique are also introduced in this peper. |
| Keywords: | digital beamforming multi-beamforming ultrasound imaging digital delay |
