Purpose of this work was to investigate k-t FOCUSS
reconstruction to accelerate real time imaging of speech
and assess its potential in clinical practise. Subjects
were studied at 1.5T scanner to produce dynamic imaging
of speech. Downsampled data created from the full
k-space data sets was reconstructed using k-t FOCUSS
with ME/MC [9]. No significant difference between SNR in
a both soft palate and intensity time profiles measured
in the fully sampled data and k-t FOCUSS reconstructions
was found for both patients and control
subjects.k-FOCUSS with ME/MC is a promising tool to
accelerate MRI acquisition for speech assessment.
