ABSTRACT:
A technique for generating "optimal" radio frequency pulses for use in creating SPAMM imaging stripes. The MR imaging operator is given an opportunity to select the desired stripe parameters for the SPAMM imaging stripe so that the resulting SPAMM imaging stripe will have the desired narrowness, sharpness, flatness and the like. These parameters are then used by an optimal pulse generating system of the invention to generate the input radio frequency pulse sequence which will produce the desired stripes. This technique allows a large family of pulse sequences with fairly similar performance to be generated by simply adjusting the relative weightings of criteria such as the narrowness, sharpness, flatness and the like for the SPAMM stripes.
