摘要

本文综述了磁共振应用中哈尔巴赫多极设计的相关概念。主要的重点是提供规划、设计和建造这种磁铁的实用指南。因此，提出了从理想系统到现实系统的磁场估计的解析方程。讨论了磁场均质化的各种策略，以及在无力的情况下打开或组合磁场的概念。温度补偿和其他实际应用方面也进行了讨论。对于磁共振两极性(二极和四极)是主要的兴趣，但更高的极性也包括在内。

Practical Concepts for Design, Construction and Application of Halbach Magnets in Magnetic Resonance

This review is a compilation of relevant concepts in designing Halbach multipoles for magnetic resonance applications. The main focus is on providing practical guidelines to plan, design and build such magnets. Therefore, analytical equations are presented for estimating the magnetic field from ideal to realistic systems. Various strategies of homogenizing magnetic fields are discussed together with concepts of opening such magnets without force or combining them for variable fields. Temperature compensation and other practical aspects are also reviewed. For magnetic resonance two polarities (di- and quadrupole) are of main interest, but higher polarities are also included.
