A method of parallel magnetic resonance imaging of a body, comprising:&#x2014;acquiring a set of elementary magnetic resonance images of said body from respective receiving antennas having known or estimated sensibility maps and noise covariance matrices, said elementary images being under-sampled in k-space; and performing regularized reconstruction of a magnetic resonance image of said body; wherein said step of performing regularized reconstruction of a magnetic resonance image is unsupervised and carried out in a discrete frame space. A method of performing dynamical and parallel magnetic resonance imaging of a body, comprising:&#x2014;acquiring a set of time series of elementary magnetic resonance images of said body from respective receiving antennas having known or estimated sensibility maps and noise covariance matrices, said elementary images being under-sampled in k-space; and performing regularized reconstruction of a time series of magnetic resonance images of said body.
