[Acoustic rhinometry and acoustic pharyngometry in the modeling of human upper respiratory tract].
Acoustic rhinometry and acoustic pharyngometry (AR/P) can quantify the upper airway condition of air draft by drawing a graph plotting the nasal cavity and pharyngeal cavity cross-sectional area. Based on CT medical images of volunteers, a 3-dimensional finite element model of upper respiratory tract was reconstructed by using the method of surface rendering. The veracity of the model was valued by comparison of the relevant areas between the model and the AR/P graph; and an AR/P was used to help improve and enrich the model. The combination of AR/ P and CT is useful in studying the medicine problem related to the anatomical structure of upper respiratory tract.
