Dynamic MRI can provide quantitative assessment on the anatomy and dynamics of the articulators in real time, but usually suffers from limited spa-tiotemporal resolution and poor spatial coverage. This work presents full-vocal-tract 3D dynamic MRI at a frame rate of 150 fps with a 2.0 mm 2.0 mm 5.0 mm spatial resolution. It is performed by incorporating an accelerated 3D acquisition scheme into a Partial Separability (PS) model-based imaging method. Subtle temporal behaviors of the articulator motion and fine 3D anatomy of the vocal tract are well captured and analyzed.
