1. An RF coil system configured for magnetic resonance applications, comprising:
- a multi-channel RF coil transceiver configured to excite an RF field in an RF coil and/or receive RF signals from the RF coil; and
a multi-channel RF coil connected to the multi-channel RF coil transceiver, the multi-channel RF coil configured for nuclear magnetic resonance (NMR) imaging, wherein;
the RF coil system being structured for reconfiguration between a plurality of operational modes, wherein at least one of the plurality of operational modes is a frequency dual tuned, reactively coupled, multi-nuclear, multi-channel mode with at least one operational frequency driven in a multi-channel mode, wherein a first subset of one or more current elements of the multi-channel RF coil are tuned to a first frequency associated with a first nuclei, and a second subset of one or more elements of the multi-channel RF coil are tuned to a second frequency associated with a second nuclei, which allows magnetic resonance imaging to occur simultaneously over both the first and second frequency.
