    • Disclosed herein is a beamforming apparatus (200) for beamforming signals which are transmitted or received by a probe (100) which includes a plurality of transducer blocks (110, 120, 130, 140), each of which includes a plurality of transducers (111 - 143). The apparatus (200) includes a controller (210) configured to control components to delay signals to be transmitted by the plurality of transducers (111 - 143) included in each transducer block (110, 120, 130, 140) or signals received by the plurality of transducers (111 - 143) included in each transducer block (110, 120, 130, 140), and an analog beamformer (300) which includes a plurality of beamforming units (310, 320, 330, 340) which correspond to the respective transducer blocks (110, 120, 130, 140). The plurality of beamforming units (310, 320, 330, 340) is configured to perform analog beamforming on signals transmitted or received by the plurality of transducers (111 - 143) included in each transducer block (110, 120, 130, 140) based on a control signal which is received from the controller (210), to reduce a dynamic delay range, thereby reducing a size of a delay line.
    • 本文公开了一种用于波束成形信号的波束成形装置(200),其由包括多个换能器块(110,120,130,140)的探头(100)发送或接收,每个换能器块包括多个换能器(111 - 143)。 装置(200)包括控制器(210),其被配置为控制部件以延迟要由包括在每个换能器块(110,120,130,140)中的多个换能器(111-143)发射的信号或由 包括在每个换能器块(110,120,130,140)中的多个换能器(111-143)以及模拟波束形成器(300),其包括多个波束成形单元(310,320,330,340),其对应于 各个换能器块(110,120,130,140)。 多个波束形成单元(310,320,330,340)被配置为对由包括在每个换能器块(110,120,130,140)中的多个换能器(111-143)所发送或接收的信号执行模拟波束成形 在从控制器(210)接收的控制信号上减少动态延迟范围,从而减小延迟线的大小。
