The present invention improves the quality of the magnitude and phase images produced in medical imaging, in particular in the case of multi-antenna MRI. The invention proposes to generate () such an image (I) by summing the complex image data (p,{tilde over (p)}) obtained from different antennas by weighting these data using only the diagonal elements (R) of an antenna noise covariance matrix or its inverse or pseudo-inverse matrix (R). A reference antenna (Ref) may be determined (), so as to be able to replace (), in each of these datum, a phase component specific to the acquisition antenna by a reference phase component. The reference antenna is preferably a virtual antenna formed by linear combination of the antennas of the MRI system. If significant improvements are obtained in the phase image resulting from the summation, a very clear gain is also surprisingly obtained in the magnitude image.
