MRI
has become the preferred technique to study the dynamics of tongue and vocal
tract during speech, singing or instrument playing. Recent advances provide
access to qualitative information of fast tongue movements at very high
temporal resolution. In this study, real-time MRI using highly undersampled radial
FLASH with regularized nonlinear inverse reconstruction was used to monitor the
dynamics of the tongue at 10 ms, 18 ms and 33 ms resolution. The effect of
different temporal resolutions on the tongue and oral cavity during speech will
be compared and analyzed.
