Abstract: Disclosed are a method of detecting a neuron resonance signal and an MRI signal processing apparatus. The method of detecting a neuron resonance signal includes acquiring a plurality of different digital sequences respectively corresponding to a plurality of different repetition periods by sampling a magnetic resonance signal of a neuron resonance signal according to each of the plurality of different repetition periods and calculating correlation between the plurality of different digital sequences in a frequency band based on the plurality of different digital sequences.

Abstract: Provided is a method for generating MRI data including applying, by an MRI computing device, an RF excitation pulse, and completing, by the MRI computing device, a K-space by acquiring a plurality of phase encoding line groups, in a state in which any other RF excitation pulse is not applied after applying the RF excitation pulse, in which each of the plurality of phase encoding line groups includes a plurality of phase encoding lines, and an absolute value of an average phase encoding size of a phase encoding line group acquired earlier is not greater than an absolute value of an average phase encoding size of a phase encoding line group acquired later, among the plurality of phase encoding line groups.
