Small-Tip-Angle Spokes Pulse Design Using Interleaved Greedy and Local Optimization Methods

Current spokes pulse design methods can be grouped into methods based either on sparse approximation or on iterative local (gradient descent-based) optimization of the transverse-plane spatial frequency locations visited by the spokes. These two classes of methods have complementary strengths and we...
