Various methods and systems are provided for a current trap. In one example, the current trap has a flat core made of a nonconductive material, a coiled wire having a plurality of turns winding around the flat spiral core, and one or more tuning capacitors physically attached to the flat core and electrically connected to the coiled wire to form a resonant circuit with the coiled wire.

Methods and systems for a floating cable trap

Various methods and systems are provided for radio frequency coil units for magnetic resonance imaging. In one example, a radio frequency (RF) coil unit for magnetic resonance imaging (MM) includes an outer layer forming an exterior of the RF coil unit, a pressure reservoir enclosed by the outer layer, wherein the pressure reservoir forms a sealed chamber, and an array of RF coil elements enclosed by the outer layer, wherein the array of RF coil elements is disposed outside of the sealed chamber of the pressure reservoir.

An apparatus for decoupling a receive coil from a transmit coil includes a tuning circuit connected electrically with the receive coil and a MEMS switch connected electrically in parallel with the tuning circuit, and operable to line up or to bypass the tuning circuit by opening or closing the MEMS switch. The apparatus further includes a control circuit operatively connected with the MEMS switch and operable to open or to close the MEMS within a window of time responsive to energization of the transmit coil to transmit a signal.

Apparatus and method for decoupling an MRI receive coil

Systems and devices for transmitting radio frequency signals to and from radio frequency coils in magnetic resonance imaging systems are provided. In one embodiment, a balun for blocking induced radio frequency current on ground conductors of a multi-layer signal carrier includes first and second insulative elements disposed on first and second sides of the signal carrier, respectively, a conductive layer partially surrounding ends of each insulative element with a central region of each insulative element not surrounded by the respective conductive layer, first and second capacitive circuits coupled to the conductive layers of each respective insulative element in the central region thereof, vias extending through the signal carrier, and conductive material disposed in the vias electrically coupling a conductive layer on respective ends of the first and second elements with one another and with the ground conductors.

Magnetic resonance compatible multichannel stripline balun

A phased array coil for a Magnetic Resonance Imaging (MRI) system is provided that includes a first coil, a second coil adjacent the first coil, and a third coil adjacent the second coil. The first, second and third coils are configured in a parallel arrangement in a left-right direction of the MRI system.
