The aim of this work was to investigate the performance
of k-t BLAST scheme when applied to real-time imaging of
speech. We were particularly interested to determine if
this method could be used clinically to visualize soft
palate motion and velopharyngeal closure during speech.
We have also investigated k-t FOCUSS algorithm for
reconstruction of dynamic speech data and compared it
with commercially available k-t BLAST reconstruction.
K-t BLAST scheme is a promising tool to accelerate MRI
for speech imaging. K-t FOCUSS reconstruction allowed to
improve quality of the images.
