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.
