摘　　要：鼻/咽声反射仪是通过绘制鼻腔和咽腔横截面积曲线来确定呼吸道通气状况的仪器。基于CT图像,应用表面重建的方法建立正常人体上呼吸道三维有限元模型。将模型中得到的鼻腔和咽腔横截面积值与声反射仪实际测量值进行对比,来校验并完善所建人体上呼吸道三维有限元模型。CT与声反射仪的结合为解决与人体上呼吸道解剖结构相关的医学问题提供有益的补充。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.
