This project examines tongue surface shapes and internal strains using supine ultrasound and tagged Cine-MRI (tMRI) images. Mid-sagittal tongue slices were recorded for identical utterances and as similar a recording procedure as possible for both instruments. Tongue surface contours, extracted from ultrasound and conventional MRI, were registered. Local measures of Eulerian strain fields were extracted from the tMRI. Visual groupings of local internal strains were done.
