PARALLEL MRI WITH SENSITIVITY MAPPING USING RF COIL Russian patent published in 2019 - IPC G01R33/24 

FIELD: medicine.

SUBSTANCE: using: for magnetic resonance imaging (MRI) of an object. Gist of the invention is that the object is exposed to a sequence of stimulated echo signals. Two or more stimulated echo signals (STE, STE*) are received, namely, a direct stimulated echo signal (STE) and coupled stimulated echo signal (STE*), moreover, at least one of the stimulated echo signals (STE, STE*) are received in parallel through a matrix of two or more RF receiving antennas with different spatial sensitivity profiles, and at the same time at least another of the mentioned stimulated echo signals (STE, STE*) is received through the RF coil for the whole body, which has an almost uniform spatial sensitivity profile. Sensitivity maps indicating the spatial sensitivity profiles of individual RF receiving antennas of the array are derived by comparing stimulated echo signals (STE, STE*) received through the RF receiving antenna with stimulated echo signals (STE, STE*) received through the RF coil for the whole body.

EFFECT: technical result: the provision of the possibility of creating an improved MRI technology, which allows for rapid and reliable determination of the spatial sensitivity profiles of RF receiving antennas used in parallel tomography.
