脑功能的核磁共振成像

Nuclear magnetic resonance imaging of human brain function

功能性磁共振成像技术（ｆＭＲＩ）是研究大脑认识思维活动过程的强有力工具。本文阐述ｆＭＲＩ信号变化的物理基础和ｆＭＲＩ的成像新技术，分析了ｆＭＲＩ中的硬件特点，并展望了ｆＭＲＩ成像方法的前景。

Functional nuclear magnetic resonance imaging(fMRI) is an effective technique to study human brain mental activity. This paper elaborates the physical foundation of fMRI signal and new imaging techniques of fMRI, analyzes the hardware characteristics of fMRI and discusses the future development of fMRI.
