The content of this volume has been added to eMagRes (formerly Encyclopedia of Magnetic Resonance) - the ultimate online resource for NMR and MRI . To date there is no single reference aimed at teaching the art of applications guided coil design for use in MRI. This RF Coils for MRI handbook is intended to become this reference. Heretofore, much of the know-how of RF coil design is bottled up in various industry and academic laboratories around the world. Some of this information on coil technologies and applications techniques has been disseminated through the literature, while more of this knowledge has been withheld for competitive or proprietary advantage. Of the published works, the record of technology development is often incomplete and misleading, accurate referencing and attribution assignment being tantamount to admission of patent infringement in the commercial arena. Accordingly, the literature on RF coil design is fragmented and confusing. There are no texts and few courses offered to teach this material. Mastery of the art and science of RF coil design is perhaps best achieved through the learning that comes with a long career in the field at multiple places of employment...until now. RF Coils for MRI combines the lifetime understanding and expertise of many of the senior designers in the field into a single, practical training manual. It informs the engineer on part numbers and sources of component materials, equipment, engineering services and consulting to enable anyone with electronics bench experience to build, test and interface a coil. The handbook teaches the MR system user how to safely and successfully implement the coil for its intended application. The comprehensive articles also include information required by the scientist or physician to predict respective experiment or clinical performance of a coil for a variety of common applications. It is expected that RF Coils for MRI becomes an important resource for engineers, technicians, scientists, and physicians wanting to safely and successfully buy or build and use MR coils in the clinic or laboratory. Similarly, this guidebook provides teaching material for students, fellows and residents wanting to better understand the theory and operation of RF coils. Many of the articles have been written by the pioneers and developers of coils, arrays and probes, so this is all first hand information! The handbook serves as an expository guide for hands-on radiologists, radiographers, physicians, engineers, medical physicists, technologists, and for anyone with interests in building or selecting and using RF coils to achieve best clinical or experimental results. About EMR Handbooks / eMagRes Handbooks The Encyclopedia of Magnetic Resonance (up to 2012) and eMagRes (from 2013 onward) publish a wide range of online articles on all aspects of magnetic resonance in physics, chemistry, biology and medicine. The existence of this large number of articles, written by experts in various fields, is enabling the publication of a series of EMR Handbooks / eMagRes Handbooks on specific areas of NMR and MRI. The chapters of each of these handbooks will comprise a carefully chosen selection of articles from eMagRes . In consultation with the eMagRes Editorial Board, the EMR Handbooks / eMagRes Handbooks are coherently planned in advance by specially-selected Editors, and new articles are written (together with updates of some already existing articles) to give appropriate complete coverage. The handbooks are intended to be of value and interest to research students, postdoctoral fellows and other researchers learning about the scientific area in question and undertaking relevant experiments, whether in academia or industry.

这本书的出现,简直是给那些在MRI影像技术领域苦苦钻研的学生和工程师们吃了一颗定心丸!我们都知道,MRI图像的质量很大程度上取决于RF线圈的设计和性能,但相关的技术细节往往隐藏在深奥的物理公式和晦涩的工程文献中。作为一名刚入行的技术支持人员,我经常面对客户关于图像信号弱、视野不均匀、特定部位成像效果不佳的疑问,而这些问题很多都追溯到RF线圈。我迫切需要一本能够清晰解释RF线圈如何产生和接收射频信号、如何影响局部磁场均匀性、如何克服电磁损耗、以及如何通过优化设计来提升信噪比和空间分辨率的书。如果这本书能提供一些实际的设计案例分析,展示不同几何结构、不同材料选择、不同线圈布局对成像结果的影响,并且能够深入浅出地介绍如SENSE、GRAPPA等加速成像技术与RF线圈紧密相关的部分,那无疑会极大地拓宽我的视野,提升我为客户提供专业技术咨询的能力。我尤其希望它能涵盖一些关于新型RF线圈技术,比如柔性线圈、超导线圈、甚至是微型化RF线圈在特殊应用(如介入MRI)中的潜力,让我能与时俱进,跟上行业发展的步伐。
评分作为一名在临床放射科工作的医师,我深知MRI图像质量对于诊断的准确性至关重要,而RF线圈无疑是影响图像质量的关键因素之一。然而,在日常的临床实践中,我们更多地关注的是如何选择合适的序列、如何优化参数以获得最佳的诊断信息,对于RF线圈的具体设计和原理往往了解有限。这本书如果能提供一些关于RF线圈在不同临床应用场景下的表现分析,比如在神经成像、骨骼肌肉成像、腹部成像或心脏成像中,不同类型的RF线圈会带来哪些优势或局限性,以及它们如何影响图像的信噪比、对比度、空间分辨率和伪影。我尤其希望书中能够解释,为什么在某些情况下,需要使用特殊的RF线圈,比如高密度阵列线圈、高开口率线圈,以及它们如何帮助克服特定解剖结构的成像挑战。此外,如果书中能够对RF线圈的维护、保养以及常见问题的排查提供一些指导性建议,那将极大地帮助我们放射科团队更好地使用和管理MRI设备,从而提升整体的成像质量和诊断效率。我期待这本书能够成为连接我们临床医师与RF线圈工程技术之间的一座桥梁,让我们能够更深入地理解设备,从而更好地服务于患者。
评分作为一名在磁共振成像领域摸爬滚打多年的研究人员,我一直对RF线圈的奥秘充满好奇,但同时也深感其复杂性。市面上关于MRI的书籍琳琅满目,许多都聚焦于成像原理、序列设计或者图像处理,能够深入剖析RF线圈设计与应用的却屈指可数。我曾经花费不少时间在各种学术期刊上零散地搜寻信息,试图构建起对RF线圈的系统认知,然而,这种碎片化的学习方式效率低下,且容易遗漏关键细节。想象一下,如果能有一本书,能像经验丰富的导师一样,循序渐进地引导我理解从基础电磁学原理到现代多通道线圈设计,再到实际应用中的优化策略,该是多么令人兴奋的事情!这本书如果能系统地梳理RF线圈的演进历史,探讨不同类型线圈(如表面线圈、体积线圈、鸟笼线圈、相控阵线圈等)的原理、优缺点及其适用场景,并且详细阐述在实际MRI系统中,RF线圈如何与梯度线圈、主磁场协同工作,如何影响图像质量(如信噪比、空间分辨率、伪影等),那绝对会是MRI领域的一本宝藏。我期待它能为我这样的实践者提供一个清晰、全面的技术视角,帮助我更好地理解和解决实际工作中遇到的RF线圈相关问题,甚至启发新的研究方向。
评分我是一名对MRI技术充满好奇的科普爱好者,虽然我不是专业的医生或工程师,但我一直对MRI神奇的成像能力感到着迷,尤其是其中隐藏的各种技术细节。每次去医院做检查,看到那些复杂的机器和精美的图像,我都会想,这些图像是如何被“制造”出来的?RF线圈,这个听起来就有些高深莫测的设备,到底扮演着怎样的角色?我希望有一本书,能够用一种更加通俗易懂、引人入胜的方式,为我揭示RF线圈的神秘面纱。它或许可以从RF线圈的“诞生”讲起,用生动形象的比喻解释电磁波如何在人体内部激荡,又是如何被巧妙地“捕捉”回来。这本书可以介绍不同形状的RF线圈,比如为什么有的看起来像一个巨大的环,有的又贴得很紧密,它们分别适合扫描身体的哪些部位,又是如何保证成像的清晰和准确的。如果还能穿插一些MRI发展的历史故事,或者介绍一些在RF线圈研究领域做出杰出贡献的科学家,那就更好了。我渴望通过这本书,不仅能理解RF线圈的基本原理,更能感受到科学探索的魅力,为自己打开一扇了解前沿医学影像技术的大门,而这一切,都无需让我沉浸在枯燥的公式和专业术语之中。
评分作为一名长期从事MRI设备开发,尤其是RF系统部分的工程师,我一直在寻找一本能够全面、深入地阐述RF线圈设计理论及其在实际应用中的挑战的书籍。我们知道,RF线圈的设计是一个高度交叉的学科,需要结合电磁场理论、电路理论、材料科学、以及对MRI成像物理过程的深刻理解。市面上很多书籍要么过于偏重理论,公式推导冗长,难以与实际工程落地;要么过于偏重应用,但对底层设计原理的解释又不甚清晰。我非常期待这本书能够提供一个扎实的理论基础,例如详细讲解线圈的阻抗匹配、品质因数、电磁耦合、寄生效应等关键参数如何影响线圈的性能,以及如何通过仿真工具(如COMSOL、ANSYS HFSS等)进行线圈的建模和优化。更重要的是,我希望它能深入探讨不同材料(如铜、银、碳纤维等)在RF线圈设计中的应用,以及它们对导电性、损耗、机械性能的影响。此外,书中关于制造工艺、屏蔽技术、以及如何处理高场MRI中可能出现的电磁兼容性问题等实用信息,如果能得到详细的介绍,那将是极大的帮助。我希望能通过这本书,进一步提升我在RF线圈设计方面的专业技能,攻克更多技术难题。
