An exemplary coil arrangement can be provided, which can include, for example, coil element(s) having a parallel resonant circuit at a port, where the coil element(s) is detuned by causing a low impedance at the port. Pre-amplifier arrangements can provide a low impedance at the port of the coil element(s) to suppress the induced current on the coil element(s) thereby reducing the inductive coupling to neighboring element(s). The coil element(s) can include an inductance and a capacitance which cancel each other out. The inductance and the capacitance can cancel each other out such that an impedance of the coil element has no imaginary part at a working frequency. An impedance of the coil element(s) in free space includes a real part that can be greater than a sum of losses for the coil element(s).

Receive coil arrangement and method for use thereof

An apparatus can be provided that can include a plurality of electric dipole antenna arrangements, and a processing arrangement configured to receive a signal(s) from the electric dipole antenna arrangements, and generate a magnetic resonance image based on the signal(s). Each of the electric dipole antenna arrangements can have at least two poles extending in opposite directions from each other. One of the poles can have a curved shape, which can bifurcate and follow two mirror symmetric S-shapes.

Dipole array arrangement

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.
