This work presents a versatile new algorithm to design better spiral trajectories, by minimizing high spatial frequencies in the gradient waveform and dynamically compensating for preconditioning by adaptively changing the maximum gradient and slew rate limits. It has been integrated into software, and example waveforms are given.
