Pulse Sequence Design for Gradient Arrays in MRI

Motivation: Gradient arrays are superior compared to the conventional MR coils. However, there exists no pulse sequence design algorithm for the optimum use of the gradient array. Goal(s): This work proposes a novel pulse sequence design schema for the optimum use of the gradient arraysApproach: The algorithm utilizes a waveform optimization method. This method provides the shortest trapezoidal pulses with three inputs: the area to cover, starting and ending amplitudes. Results: The algorithm is fit for any gradient array weight matrix with an arbitrary number of channels. It can provide the shortest timing values for any imaging plane while preserving the hardware limits. Impact: There exists no pulse sequence design algorithm for the optimum use of the gradient array. We present a novel algorithm fit for any gradient array weighting with an arbitrary number of channels while providing the shortest timing values.
