The study introduces a new concept for spin excitation and signal acquisition in MRI using rapid rotation of a single RF coil about a sample. The authors constructed a rotating RF coil system for 2 and 4.7 Tesla imaging to enable rapid rotation of a single RF coil for spin excitation and signal acquisition. Images of biological specimens acquired with the rotating coil were comparable to conventional RF coils, and the approach could eliminate the need for multiple channels and complex RF decoupling, potentially advancing multichannel array technology. It is hoped that hardware advantages of coil rotation and the additional parameter of rotational velocity will initiate advances in MRI through the development of new sequences and methods. © 2009 Wiley Periodicals, Inc., Concepts Magn Reson Part B 35B: 59–66.
Abstract This article introduces a new concept for spin excitation and signal acquisition in magnetic resonance imaging (MRI) using rapid rotation of a single radiofrequency (RF) coil about a sample. A rotating RF coil system was constructed for 2 and 4.7 Tesla imaging. The acquired images of biological specimens were comparable to those of a conventional RF coil system. This approach may obviate the need for multiple channels and intricate RF decoupling of many coils, which impede the progress of multichannel array technology. It is hoped that hardware advantages of coil rotation and the additional parameter of rotational velocity will initiate advances in MRI through the development of new sequences and methods. © 2009 Wiley Periodicals, Inc.
