Keywords: RF Pulse Design & Fields, High-Field MRIThe Universal Pulse (UP) concept to parallel transmission radiofrequency (RF) pulse design was introduced to avoid time consuming B1+ and ΔB0 data acquisition before each clinical scan. Introduced large flip angle design methods utilize kT-point trajectories and small tip angle approximation. In this work, new quasi damping scheme for Newton's methods method is introduced for large flip angle universal pulse design using numerical solution of the Bloch equation. Introduced quasi-damping scheme can be utilized in large flip angle Universal Pulse design for all flip angles including 180o pulses, without the loss of performance.
