因此相控阵列能够更加灵活、准确而快速地实现多样化的焦点模式和焦点扫描控制，是非常理想的声束聚焦手段。

So phased array is an ideal applicator that can congregate ultrasound beam and shift the focus more flexibly, rapidly and accurately.

与传统的超声波探头相比，超声相控阵探头可以实现电子控制下的声束平移、偏转与动态聚焦。

Compared with traditional ultrasonic probe, ultrasonic phased array probe can realize transition, deflection and dynamic focusing of acoustic beam under electronic control.
