扩散磁共振成像（dMRI）建模的最新进展导致了几种用于重建扩散信号的最新方法的发展。这些方法允许计算不同的特征，这些特征又反映了大脑和其他器官中纤维组织的特性。一个实际的考虑是，在这些方法中进行选择需要非常专业的知识。为了弥合dMRI重建和分析理论与实践之间的差距，我们对dMRI建模文献进行了详细的回顾。我们把重点放在数学和算法的基础上的主题，现有的方法分类，根据他们如何对待扩散信号的角度和径向采样。我们描述的功能，可以计算每种方法，并讨论其优点和局限性。我们还提供了详细的参考书目，以指导读者。(C)2011 Elsevier B.V.保留所有权利。
Recent advances in diffusion magnetic resonance image (dMRI) modeling have led to the development of several state of the art methods for reconstructing the diffusion signal. These methods allow for distinct features to be computed, which in turn reflect properties of fibrous tissue in the brain and in other organs. A practical consideration is that to choose among these approaches requires very specialized knowledge. In order to bridge the gap between theory and practice in dMRI reconstruction and analysis we present a detailed review of the dMRI modeling literature. We place an emphasis on the mathematical and algorithmic underpinnings of the subject, categorizing existing methods according to how they treat the angular and radial sampling of the diffusion signal. We describe the features that can be computed with each method and discuss its advantages and limitations. We also provide a detailed bibliography to guide the reader. (C) 2011 Elsevier B.V.
