Open the CIPO recordAbstract From the Canadian patent
A method of obtaining an NMR 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°. The magnetization is then repeatedly reversed 180° so as to produce a spin echo train. Simultaneously with the preceding steps, Ga and Gb sequences are applied in which the values of GA and Gb remain constant over each spin echo while the absolute values or preferable their actual values thereof change from respective adjacent spin echoes pre-, ferably incrementally in co-sinusoidal relationship. The tipping and reversing of the magnetization vector is preferably accomplished by means of rf pulses.
