This work provides a method to incorporate B1 sensitivity considerations into the optimization of quantitative magnetization transfer (qMT) data acquisition. This is achieved by regularizing the Cramer-Rao lower bound optimization condition with a B1 sensitivity term. The framework, qMT-optimization, helps designing qMT acquisition protocols optimized for robustness against inaccuracies of auxiliary measurements. Several demos are included in this package. qMT-optimization toolbox wraps around qMRLab, an open-source software for quantitative MR image analysis. Therefore, some features may require knowledge of qMRLab GUI features.
