基于FPGA的核磁共振成像仪通信主控系统设计

Design of Communication Main Control System of MRI Based on FPGA

文章用主控板的设计方式提出一种新的成像系统设计。利用FPGA开发板作为主控板,通过对NiosⅡ协处理器上移植相应的操作系统和协议栈,实现了与计算机之间的通信,同时生成相应脉冲序列,进而实现用户要求。经验证本文所设计的主控板可有效增加成像系统的精度和稳定性。

A new design method of main control board for imaging system is proposed.FPGA development board is used as the main control board.By transplanting the corresponding operating system and protocol stack to NiosⅡcoprocessor,the communication with computer is realized,and the corresponding pulse sequence is generated,so as to meet the user’s requirements.After verification,it is found that the main control board designed in this paper can effectively increase the accuracy and stability of the imaging system.
