This patent describes a method for generating a computed NMR having improved signal-to-noise ratio relative to an acquired NMR image corresponding to substantially similar timing parameters. The method comprises the steps of: exciting, spatially encoding and detecting NMR signals in a sample object to obtain acquired images according to a timing parameter which varies between acquired images; fitting NMR data corresponding to each pixel of the acquired images into an equation relating NMR parameters of the object to the NMR signals in order to produce fitted equational and generating the computed image corresponding to a single value of the timing parameter using the fitted equations.
