SPIN-ECHO MR-VISUALIZATION Russian patent published in 2019 - IPC G01R33/561 

FIELD: physics.

SUBSTANCE: group of inventions relates to magnetic resonance (MR) imaging. MR-visualization comprises the steps of: subjecting the object to the imaging sequence of the RF pulses and switched magnetic field gradients, wherein the visualizing sequence is a stationary sequence comprising a plurality of reusable data collection units, wherein each data collection unit comprises two segments immediately following each other, namely: i) a first segment starting from the RF excitation pulse emitted to the object, wherein the duration of the first segment is integral with the predetermined time interval T, and ii) a second segment starting from the refocusing RF pulse emitted to the object and having a reading magnetic field gradient and a phase encoding magnetic field gradient, wherein duration of second segment is integral with time interval T of collection of one or more phase-coded spin-echo signals in sequence of data acquisition units and reconstruction of one or more MR-images from collected signals of spin echo.

EFFECT: technical result is improved quality of the obtained image of an object when performing MR imaging.
