To accelerate dynamic 3-D imaging of the vocal tract during articulation, a stack-of-stars sequence with golden angle rotation and iterative reconstruction was implemented. Phase correction, peripheral under-sampling, temporal and spatial regularization were applied to reach an acquisition time of 1.3 seconds. The vocal tract modifications of one subject could be successfully analyzed at discrete time steps during phonation of a long note.
