FIELD: medical equipment.
SUBSTANCE: group of inventions relates to a magnetic resonance imaging system. Magnetic resonance imaging system comprises a gradient system and a processor for controlling the magnetic resonance imaging system. Execution of computer-executable instructions causes a magnetic resonance imaging system: obtaining by coil elements first magnetic resonance data simultaneously from a group of passive local probes, the first group of passive local probes comprising a plurality of passive local probes spaced apart from each other; to separate contributions from separate local probes into first magnetic resonance data; calculate, for a magnetic resonance imaging system, a gradient pulse response function of the gradient system using first magnetic resonance data from local probes; determining correction coefficients using a gradient impulse response function.
EFFECT: technical result is simplification of device design.
