摘　　要：随着医学超声成像系统的不断发展,电容式微机械超声换能器(CMUT)的应用日益增多。为了满足电容式微机械超声换能器在超声采集过程中的实时性、高精度、多通道数据采集需求,基于Altera公司的EP4CE10F17C8型号芯片,结合16位8通道的同步采样芯片AD7606进行CMUT超声换能器信号的采集与传输,实现CMUT超声换能器的信号处理、采集、传输与显示一体化。With the continuous development of medical ultrasound imaging systems,the application of capacitive micro mechanical ultrasound transducers(CMUT)is increasing.In order to meet the real-time,high-precision,and multichannel data acquisition requirements of capacitive micro mechanical ultrasonic transducers in the ultrasonic acquisition process,based on Altera's EP4CE10F17C8 chip,combined with a 16 bit 8-channel synchronous sampling chip AD7606,the CMUT ultrasonic transducer signal is collected and transmitted,achieving the integration of signal processing,acquisition,transmission,and display of the CMUT ultrasonic transducer.
