Abstract
In accordance with certain exemplary embodiments of the present disclosure, provided herein are apparatus, systems and methods for, e.g., facilitating signal excitation and/or reception in a magnetic resonance system, such as, e.g., a system configured for magnetic resonance imaging (MRI) and/or spectroscopy. For example, exemplary embodiments of a method for traveling wave imaging in an MRI system can include, e.g., a circular conductive structure lying in a transverse plane within the scanner bore. The exemplary structure can be concentric with the center of the scanner RF shield. The structure can be arranged to have a resonant mode at the MR frequency characterized by a current pattern which can be configured to excite and receive an exemplary waveguide mode. The exemplary current pattern can be further configured to facilitate traveling wave imaging, for example.
