On the Generation of Half-Sinc Pulses for Optimal Excitation Profile

Keith Wachowicz¹, B. Gino Fallone^2,3

In this work, we perform simulations to explore the effects of fast T2 relaxation on excitation with half-sinc pulses. The generation of pulses for optimal excitation profiles is explored in terms of optimal flip angle, for which standard reasoning used for longer T2 species will no longer hold. Also, the number of side lobes to generate an optimal excitation profile was investigated, since, unlike the case of longer T2, using more side-lobes does not necessarily result in a better profile.
