Ultra high-frequency sound waves are used to create movies of planar tongue motion. The 2D planar motion can be reconstructed into 3D surface motion.

Our applications of this technology include:

‌	Head and Transducer Support (HATS) System More Information			Mid-sagittal Ultrasound image of the tongue (Image of 'I') Ultrasound movies Fun movies
	Edge detection of tongue contours using EdgeTrak			3D Reconstruction of the tongue surface from ultrasound. (Image of 'l') More 3D surfaces 3D Movies
‌	Visualizes and compares multiple contours using SURFACES.
