T2*-weighted MRI has broad applications in the brain and can provide both functional and (micro) anatomical information. Unfortunately, it has proven rather sensitive to subtle head motion, and the associated changes in B0 and to a lesser extent B1. In this study, the collective impact of pose-dependent B0 and B1 on T2*-weighted gradient echo MRI was investigated. A conjugate-gradient method was utilized for reconstructing MR images collected during variation of head poses.
