CREATION OF A MAGNETIC RESONANCE FINGERPRINTING DICTIONARY USING AN ADDITIONAL MAGNETIC FIELD COIL Russian patent published in 2020 - IPC G01R33/30 

FIELD: magnetic resonance imaging.

SUBSTANCE: invention can be used for compiling dictionaries for magnetic resonance fingerprinting. Essence of the invention consists in the fact that the instrument contains a magnetic resonance system for measuring magnetic resonance data of the dictionary from the measurement zone. Magnetic resonance system comprises magnet to generate main magnetic field in measurement zone. Magnetic resonance system comprises a test fixture for holding the test sample in the measurement zone. Test device comprises additional magnetic field coil and magnetic resonance antenna. Method comprises stages of multiple selection of electric current; supplying electric current to the coil of the additional magnetic field for adjustment of the main magnetic field in the measurement zone; obtaining magnetic resonance data of the dictionary from the test sample using a magnetic resonance antenna by controlling the magnetic resonance system according to the method of magnetic resonance fingerprinting and adding magnetic resonance dictionary data to the dictionary of magnetic resonance fingerprinting.

EFFECT: making it possible to obtain a dictionary of magnetic resonance fingerprinting, which can be empirically useful for providing a more accurate diagnostic tool.
