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.
