发明名称 NMR imaging method
摘要 In an imaging method called spin warp method in which a measuring sequence inclusive of nuclear spin excitation, application of phase-encoding gradient field, and measurement of NMR signals under the application of read-out gradient field, is repeated while changing the phase-encoding amount, and a data train thus obtained is subjected to the two-dimensional inverse Fourier transformation to reconstruct a magnetization distribution image of an object, wherein an NMR imaging method is characterized in that measurement of NMR signals is repeated a plural number of times for a particular phase-encoding amount only among many phase-encoding amounts, a plurality of NMR signals thus obtained are added up together and are averaged, and the data obtained by the addition and averaging is subjected to the two-dimensional inverse Fourier transformation.
