The mechanical actions of swallowing in one volunteer were modeled in three dimensions. Biplane fluoroscopy and dynamic ultrafast computed tomography of adjacent levels of the pharynx were performed during swallows of liquid. Synchronized posteroanterior, lateral, and cross-sectional images were scanned and aligned in three dimensions with graphics-animation software. Modeling the oropharyngeal swallow helps analysis and visualization of the mechanics of swallowing, dysphagia, and compensatory therapeutic strategies.
