Abstract: Aspects relate to providing radio frequency components responsive to magnetic resonance signals. According to some aspects, a radio frequency component comprises at least one coil having a conductor arranged in a plurality of turns oriented about a region of interest to respond to corresponding magnetic resonant signal components. According to some aspects, the radio frequency component comprises a plurality of coils oriented to respond to corresponding magnetic resonant signal components. According to some aspects, an optimization is used to determine a configuration for at least one radio frequency coil.

Abstract: In some aspects, a method of operating a magnetic resonance imaging system comprising a B0 magnet and at least one thermal management component configured to transfer heat away from the B0 magnet during operation is provided. The method comprises providing operating power to the B0 magnet, monitoring a temperature of the B0 magnet to determine a current temperature of the B0 magnet, and operating the at least one thermal management component at less than operational capacity in response to an occurrence of at least one event.

Abstract: According to some aspects, a method of suppressing noise in an environment of a magnetic resonance imaging system is provided. The method comprising estimating a transfer function based on multiple calibration measurements obtained from the environment by at least one primary coil and at least one auxiliary sensor, respectively, estimating noise present in a magnetic resonance signal received by the at least one primary coil based at least in part on the transfer function, and suppressing noise in the magnetic resonance signal using the noise estimate.
