Deck the Halls: Behind-the-Scenes of the Real-Time Singing MRI Holiday Greeting


[MUSIC] So MRI provides great soft-tissue contrast.
So we can see structures like the tongue moving while someone is
speaking, or singing in this case. But traditionally the drawback
for MRI has been that it is a slow modality. It acquires a
single data point at a time and it takes a while to make an image. So what we have done today is we have
used some work by Zhi-Pei Liang at the Beckman Institute
to accelerate our image acquisition by separating the spatial
and temporal information from our acquisition. So what this will allow us to do is to create
a movie at a hundred frames-per-second with a two millimeter spatial resolution. The movie is a midsagittal plane of
her singing Deck the Halls. So we will be able to see her tongue movement
and articulation of her other oral structures. Normally we would call this
Dynamic Speech Imaging. But this time we are calling it
Speech Articulography Noel-Time Acquisition. So SANTA for our acronym. Okay. Are you ready to sing? [MUSIC] Deck the halls with boughs of holly, Fa la la la la, la la la la. Tis the season to be jolly, Fa la la la la, la la la la. Don we now our gay apparel, Fa la la, la la la, la la la. Toll the ancient Yuletide carol, Fa la la la la, la la la la. See the blazing Yule before us, Fa la la la la, la la la la. Strike the harp and join the chorus. Fa la la la la, la la la la. Follow me in merry measure, Fa la la la la, la la la la. While I tell of Yuletide treasure, Fa la la la la, la la la la. Fast away the old year passes, Fa la la la la, la la la la. Hail the new, ye lads and lasses, Fa la la la la, la la la la. Sing we joyous, all together, Fa la la la la, la la la la. Heedless of the wind and weather, Fa la la la la, la la la la [MUSIC]
