摘　　要：医学超声内窥镜成像系统所采集的图像数据需要经过数据传输接口传入计算机进行显示。为满足系统实时显示所需的高速性和稳定性,本文设计USB同步传输接口的方案。首先介绍USB同步传输接口的FPGA程序设计、固件程序、驱动程序和应用程序设计,然后通过超声成像实验验证USB同步传输接口的正确性。Medical Ultrasonic Endoscope needs to transfer its image data to PC by USB2.0 anD reanze real-time display on PC. In order to meet the system requirement of high-speed and stability, this text selects USB isochro- nous transfer to transfer image data. The text designs the proposal of USB isochronous transfer, completes the design of FPGA program, firmware, driver and user program, and verifies the correctness of USB isochronous transfer interface by experiment in the Ultrasound imaging system.
