相控阵超声换能器是相控阵扫描显像系统的主要部件之一。医用相控阵换能器,是由许多小阵元紧密排列成一个均匀线阵,用电子技术进行相控发收,实现扇形扫描的换能器件。这种超声探头与线阵扫描换能器相比,其特点是:体积小、与体表接触面小,仅为16×10mm~2。由于它能通过小的“窗孔”透视较大视野的扇形扫描面,所以适宜于对心 Phased array ultrasound transducer phased array imaging system is one of the main components. Medical phased array transducer is closely arranged by many small array elements into a uniform linear array, with the electronic control of the phased hair, to achieve fan-shaped scanning transducer device. Compared with the linear array transducer, the ultrasonic transducer has the characteristics of small volume and small contact surface with only 16 × 10-2mm2. Because it can be through a small “window” perspective fan view of the larger scanning surface, it is suitable for heart
