A magnetic resonance (MR) system includes an MR receive channel () including: an MR coil element () configured to receive MR signals in an MR frequency band; an electronic signal processing chain () configured to process the MR signals received by the MR coil element to produce processed MR signals, wherein the electronic signal processing chain includes an equalization filter (); and a signal injector (D) configured to input a reference radio frequency (RF) signal in the MR frequency band to the signal processing chain, wherein the signal processing chain processes the reference RF signal to generate a processed reference RF signal. Equalizer electronics () are configured to adjust the equalization filter based at least on the processed reference RF signal such that the MR receive channel has a flat frequency response over the MR frequency band.

Equilization for magnetic resonance imaging (MRI) signals

An apparatus () includes: a radiofrequency (RF) coil (); a detune circuit () operatively coupled to the RF coil, wherein the detune circuit includes a decoupling inductor () configured as a transmitter (TX) inductor; and a harvester () coupled to the decoupling inductor for harvesting energy from the decoupling inductor.

A magnetic resonance (MR) receive device comprises a coil or coil array including at least one radiofrequency (RF) coil element wherein each RF coil element comprises a coil and a preamplifier connected to amplify an output of the RF coil element to generate an amplified RF signal. The MR receive device further includes an RF-over-Fiber module comprising an optical fiber, a photonic device optically coupled to send an optical signal into the optical fiber, and an RF modulator connected to modulate the optical signal by an MR signal comprising the amplified RF signal.

Apparatus for non-galvanic connection of MRI receive coil to MRI system using RF-over-fiber

A balun is provided that is suitable for use with miniature coaxial cables and that obviates the need to cut the cable in order to install the balun. A portion of each coaxial cable that extends from the RF receive coils to the RF receiver is wound multiple times around a device to form an inductor. The inductor may be used with or without a separate resonant circuit. If used with a separate resonant circuit, the inductor and the resonant circuit couple with one another to generate a coupled impedance that provides common-mode noise suppression at the frequency of interest. If used without a separate resonant circuit, the inductor formed in the cable provides an inductance and the capacitance between the windings coupled with the inductance provides a series impedance that suppresses common-mode noise at the frequency of interest.
