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