Abstract： A physical-mathematical model was proposed for the NMR relaxation processes, which can automatically identify the multi-relaxation process; the automatic separation of the spin-spin relaxation processes of water sample in a home made phantom was carried out; two kinds of proton pure spin-spin relaxation time images and two kinds of proton computed pure density images have been obtained on a 1.0T supercondlrtive magnet MR-Scanner.
