摘要
介绍了医用超声内窥镜成像系统的工作原理及超声成像驱动控制系统的设计与实现。根据超声成像系统指标,主要讨论了超声波激发、接收电路原理及具体的电路;现场可编程逻辑阵列(FPGA)作为核心控制模块完成对数据传输和相关电路及芯片的控制,主要实现了对超声波的发射、接收、A/D转换以及成像部分同步控制,电路的性能已得到实验的验证。
This paper introduces the ultrasonic imaging system for ultrasonic endoscope and illuminates the study and implementation of driving control system for ultrasonic imaging. On the basis of ultrasonic imaging system, we concretely design the emission circuit and receiving circuit. The control performances have been validated by experiments. As the Field Programmable Gate Array （FPGA） being the core of this system, the paper describes the synchronous control among the ultrasonic emission, receiving.analog-to-digital conversion and ultrasonic imaging. An FPGA is used as the kernel module to control the data transferring. related circuit and chips working.
