摘要 介绍了核磁共振脉冲序列发生器的基本结构和工作原理,从系统集成度、数据传输速率和序列存储容量等方面出发,着重探讨了近年来核磁共振脉冲序列发生器研究的进展情况,分析比较了商用和自主研发的脉冲序列发生器的优点和亟待解决的问题,并针对这些问题提出了基于USB 3.0的模块化脉冲序列发生器设计方案,该方案可以为多收发通道核磁共振成像仪的研制提供参考. Basic structure and work flow of pulse programmer in NMR spectrometer were introduced. The progress o{ pulse programmer in terms of degree of system inte-gration, rate of data transmission and memory capacity was emphasized. The advantages and disadvantages of commercial and home-build pulse programmers were compared. A modularized pulse programmer based on USB 3.0 was proposed, which might be used in magnetic resonance imaging （MRI） scanners with multichannel transceivers.
