Averaged-BOSS fMRI has been proposed as an alternative to BOSS fMRI to eliminate its spatial coverage problem. The feasibility of A-BOSS has been previously investigated. Due to the complexity presented in A-BOSS fMRI, in this work a Monte Carlo simulation has been performed for a comprehensive investigation on its achievable functional contrast and to compare the results with S1 and S2 SSFP fMRI. The obtained results show the superior absolute signal change for A-BOSS and demonstrate the desirable acquisition parameters.
