We present a new, fast, and accurate simultaneous B1 and T1 mapping method based on the "Actual Flip angle Imaging" (AFI) sequence. In terms of accuracy and signal to noise ratio it seems to outperform standard AFI B1 mapping. The quantitative T1 estimation of the presented approach is in good agreement with reference T1 measurements. The approach has been successfully tested with healthy volunteers.
