The course on RF coils: Design and build your own coil provides an overview of the basic principles of designing, constructing and testing of RF coils for both animal and human scanners. Practical sessions will cover approximately 50% of the course, in which participants will learn to build surface and volume RF coils relevant to their particular interests. More advanced topics include double-tuned coils and coil arrays. Finally, components such as hybrids, couplers, shields, baluns and isolation circuits are discussed. The course is designed for basic scientists and engineers, but also has been attended in the past by clinicians, radiographers, applications specialists and other MR users interested in gaining a better insight into RF coil technology.
