| Outline of Final Research Achievements |
We developed a highly accurate swallowing evaluation system that is noncontact, noninvasive, gentle restraint of the body, and collected motion data of thyroid cartilage of healthy subjects. Using this as evaluation data, we developed a method to measure the elevation position of thyroid cartilage by extracting a slight change of the throat surface as an image feature in subjects with small change of thyroid cartilage. Furthermore, we developed a method to evaluate swallowability from measured swallowing waveform.
At the Gifu University School of Medicine, we collected data of a patient with dysphagia by developed system. Although the patient was an elderly female, it was not able to obtain a clear swallowing waveform, but we got knowledge for system settings such as camera setting and lighting, presenting beverages, guidance on starting swallowing etc.
