摘要 目的 :磁共振波谱成像有 7类快速方法 ,它们都来自快速MRI成像方法。本文提出的奇异值分解波谱成像不同这 7类快速方法 ,它是把MRI中任意轨迹图像重建方法用于波谱成像 。 Nowadays there are 7 kinds of fast Magnetic Resonance Spectroscopic Imaging methods presented,which come from MRI techniques.In this contribution the Singular Value Decomposition Spectroscopic Imaging is different from 7 sorts of fast Spectroscopic Imaging.It applied the arbitrary trajectory reconstruction method in MRI.Then it will be favorable for design of more repid imaging techniques.
