N.m.r. imaging

摘要: A method of obtaining an N.M.R. image a specimen slice in the a-b plane is provided. The comprises tipping magnetization vector by angle other than 180°. then repeatedly reversed 180° so as to produce spin echo train. Simultaneously with preceding steps, Ga and Gb sequences are applied which values remain constant over each while absolute or preferable their actual thereof change from respective adjacent echoes, preferably incrementally co-sinusoidal relationship. reversing accomplished means rf pulses.
