Three-dimensional ultrasonic imaging method and device

Abstract

The invention is suitable for the technical field of ultrasonic imaging, and provides a three-dimensional ultrasonic imaging method and device. The three-dimensional ultrasonic imaging method comprises the following steps: grouping piezoelectric array elements in the first direction and then scanning and imaging the piezoelectric array elements by a linear mode; and scanning and imaging piezoelectric array elements in the second direction by a phased array scanning mode, wherein the first direction and the second direction are mutually orthogonal. By the method, the number of original electricsignal transmitting and receiving channels can be reduced, therefore, difficulty of stimulation of a transducer and difficulty of signal and data acquisition are reduced, and meanwhile, the cost is lowered. 本发明适用于超声成像技术领域，提供了一种三维超声成像方法及装置，包括：将第一方向的压电阵元分组后采用线性方式扫描成像；对第二方向的压电阵元采用相控阵扫描方式进行扫描成像，其中，所述第一方向与所述第二方向相互正交。通过上述方法能够将原有的电信号发送与接收的通道数减少，从而降低换能器激励与信号数据采集的难度，同时降低成本。
