Ultrasound
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 |
 |
Mid-sagittal Ultrasound image of the tongue (Image of 'I') |
|
 |
Edge detection of tongue contours using EdgeTrak |  |
3D Reconstruction of the tongue surface from ultrasound. (Image of 'l') |
|
 |
Visualizes and compares multiple contours using SURFACES. |
