用于执行扩散加权磁共振测量的方法
阅读说明:本技术 用于执行扩散加权磁共振测量的方法 (Method for performing diffusion weighted magnetic resonance measurements ) 是由 菲利普·斯克泽潘基维茨 马库斯·尼尔森 于 2018-09-07 设计创作,主要内容包括:根据本发明概念的方面,提供了一种用于扩散加权磁共振成像的方法,包括:由磁共振成像扫描仪的梯度线圈生成时间相关的磁场梯度G(t)=[G<Sub>x</Sub>(t)G<Sub>y</Sub>(t)G<Sub>z</Sub>(t)]<Sup>T</Sup>,其中梯度G相对于重聚焦脉冲在时间上是不对称的,并且其中梯度G使得<Image he="93" wi="557" file="DDA0002393351680000011.GIF" imgContent="drawing" imgFormat="GIF" orientation="portrait" inline="no"></Image>为零,其中TE是回波时间以及h(t)是时间的函数,其在重聚焦脉冲之前的间隔期间为正而在重聚焦脉冲之后的时间间隔期间为负。(According to an aspect of the present inventive concept, there is provided a method for diffusion weighted magnetic resonance imaging, comprising: generating a time-dependent magnetic field gradient G (t) [ G ]) from a gradient coil of a magnetic resonance imaging scanner x (t)G y (t)G z (t)] T Wherein the gradient G is asymmetric in time with respect to the refocusing pulse, and wherein the gradient G is such that Is zero, where TE is the echo time and h (t) is a function of time, which is positive during the interval before the refocusing pulse and negative during the time interval after the refocusing pulse.)
