用于在球体内部获得均匀磁场的表面线圈绕组轮廓
Surface Coil Winding Profile for Obtaining a Uniform Magnetic Field inside a Spheroidal Body
摘要:
均匀磁场的产生是许多物理应用中的关键问题之一,如磁共振成像、磁探针等。例如,椭球体-特别是球体-在其体内自然地保持均匀的磁场,而不需要任何匀场。此外,由于它们的旋转对称性,球体更容易生产和处理,因此值得更多的重视。然而,在球体内部产生均匀的磁场仅可能通过在其表面上保持某些电流分布。在本文中,我们已经推导出精确的表面线圈绕组轮廓长扁球体和扁球体的最先进的文献中的推导,并纠正他们在必要时重组状态。
英文摘要:
Uniform magnetic field generation is one of the key issues in many physical applications; such as magnetic resonance imaging, magnetic probs etc. There are many ways to obtain highly homogeneous fields. For instance, ellipsoidal bodies - and in special, spheroids - naturally maintain uniform magnetic field inside their bodies, without any need for shimming. Thanks to their rotational symmetry in addition, spheroids are easier to produce and handle, and therefore deserve more emphasis. However, creating a uniform magnetic field inside a spheroid is only possible via maintaining certain current profiles on its surface. In this paper we have derived exact surface coil winding profiles for both prolate and oblate spheroids by reorganizing state of the art derivations in the literature and correcting them whenever necessary.
