The present invention relates to a high-resolution magnetic resonance imaging (MRI) image generating method using a new MRI image method called a generalized series parallel imaging technique, and a recording medium thereof. In the high-resolution MRI image generating method using the generalized series parallel imaging technique according to the present invention, selecting only a predetermined low frequency band of all frequency bands, and sampling the predetermined low frequency band of all frequency bands at a lower rate than a Nyquist rate to acquire magnetic resonance data.
