摘要
随着磁共振技术的发展,磁共振信号所需要的通道数越来越多,对采样所需的采样率以及精度的要求也日益增高。相对于以往的并行模数转换器来说,基于串行的总线传输技术拥有更多优点,如更快速的传输速度、更低的设计成本等,以此达到了更加优越的传输性能,并在高速通信上普遍应用。而FPGA的灵活多变以及可重复编程的特性也决定着它更适合多路磁共振信号采集的设计。基于Xilinx公司spartan-6的ISERDES接口的多路串并转换器,实现了多路磁共振信号的采集,设计简单,开发周期短。
With the development of magnetic resonance technology,the number of channels required for magnetic resonance signals is increasing,and the sampling rate and accuracy required for sampling are also increasing.And compared to the previous parallel analog-digital converter,serial bus-based transmission technology has more advantages,such as faster transmission speed,lower design costs,etc.,aiming to achieve more superior transmission performance,and it is widely used in high-speed communications.The flexible and repeatable features of FPGAs also dictates the design of multi-channel magnetic resonance signal acquisition.This design is based on Xilinx spartan-6′s ISERDES interface,multi-channel serial and parallel converter,to achieve a multi-channel magnetic resonance signal acquisition,and the design is simple and has short development cycle.
