QUIET MR-VISUALIZATION Russian patent published in 2019 - IPC G01R33/48 

FIELD: physics.

SUBSTANCE: group of inventions relates to the field of magnetic resonance imaging (MR). Method of MR-visualization of object positioned in volume of MR-device (1) investigation, at that, method includes stages, at which: a) gradually varying the gradient vector of the magnetic field from the initial position to the final position over the plurality of intermediate positions, until a certain number of RF pulses is emitted in the presence of a magnetic field gradient; b) gradually varying the gradient vector of the magnetic field again from the initial position to the final position over the plurality of intermediate positions until a certain number of MR-echo signals is obtained in the presence of a magnetic field gradient; c) sampling spherical volume in k-space by repeating steps a) and b) a certain number of times for different initial, intermediate and/or final positions; MR image is restored from obtained MR-echo signals.

EFFECT: technical result is reduction of acoustic noise when performing magnetic resonance imaging.
