Abstract

The theoretical principles, design and construction of wave-wound radio frequency coils for low-field nuclear magnetic resonance imaging are presented. The coils can be tuned to emit and detect circularly polarized radio frequency field. The principles and design of the tuning circuit are described. The performance of the wave-wound coils and tuning circuits is analyzed on the basis of numerical simulations and experimental studies. Guidelines for the design of high performance coils are given. Four wave-wound coils have been designed and constructed for clinical magnetic resonance imaging. Properties and examples of the imaging results of these coils are presented.
