Abstract
A thorough review of the q-space technique is presented starting from a discussion of Fick's laws. The work presented here is primarily conceptual, theoretical and hopefully pedagogical. We offered the notion of molecular concentration to unify Fick's laws and diffusion MRI within a coherent conceptual framework. The fundamental relationship between diffusion MRI and the Fick's laws are carefully established. The conceptual and theoretical basis of the q-space technique is investigated from first principles.
摘要
从对菲克定律的讨论开始，对q空间技术进行了全面回顾。本文所呈现的工作主要是概念性、理论性的，希望具有教学意义。我们提出了分子浓度的概念，以便在一个连贯的概念框架内统一菲克定律和扩散磁共振成像。仔细建立了扩散磁共振成像与菲克定律之间的基本关系。从第一原理出发研究了q空间技术的概念和理论基础。
