RF Coils for MRI

JT Vaughan

Radiofrequency (RF) coils are the "antennae" of MRI instruments, used to both stimulate and receive the signals. Modern clinical and preclinical MRI systems use coil circuits ranging from single, passive LC loops to electronically controlled, multiple element phase arrays and cryogenically cooled probe-heads.

This handbook will serve as an expository guide for engineers, scientists, medical physicists, radiographers, technologists, hands-on radiologists and other physicians, and for anyone with interest in building, purchasing or selecting and using coils to achieve the best clinical or experimental results. It combines the lifetime understanding and expertise of many of the senior designers in the field into a single, practical training manual on how to design, build, and use their most effective designs. Tricks of the trade and other "proprietary" information, part numbers and sources of component materials, equipment, engineering services and consulting are all included, enabling anyone with electronics bench experience to build, test and interface a coil.

The handbook also teaches the MR system user how to safely and successfully implement the coil for its intended application. The chapters include information required by the scientist or physician to predict respective experiment or clinical performance of a coil for a variety of common applications.

RF Coils for MRI will become an important resource for engineers, technicians, scientists, and physicians wanting to safely and successfully build (or buy) and use MR coils in the laboratory of clinic. Similarly, this handbook provides teaching material for student, fellows and residents wanting to better understand the theory an operation of RF coils.

Descriere

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.
