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