In this work, we introduce the Tip Angle Doubling (TAD) principle, which makes possible to use small tip angle design methods to achieve large tip angles at no extra computation costs. Bloch equation simulations show how the method works in practice. The methods allows fast large tip angle pulse design and is applicable to multi transmit systems with B1+ inhomogeneities correction and (local) SAR optimization.
