An image processing scheme to quantitatively extract and validate hyoid bone motion based on real-time ultrasound recordings of swallowing.
An image processing technique with associated hardware was developed to quantitatively extract hyoid bone motion from realtime submandibular ultrasound images recorded during the swallowing act. Videofluorographic imaging, the "gold standard" of swallowing studies, was recorded simultaneously and synchronized to the ultrasound. Hyoid position obtained from the ultrasound was validated based on the videofluorography using personal computer-based image processing methods.
