Airway ventilation analysis system using fluid structure coupled analysis of maxillofacial area

摘要

According to the present invention, a model generation unit (12) uses a numerical analysis method to generate, on the basis of three-dimensional image data of the inside of a maxillofacial portion of a test subject, a three-dimensional shape model of the upper respiratory tract and tissues surrounding the upper respiratory tract, and a fluid model of air in the upper respiratory tract. A simulation execution unit (14) assigns unique physical property values to the three-dimensional shape model and fluid model generated by the model generation unit (12), and calculates information relating to the state of air passage in the upper respiratory tract, which varies in accordance with respiration, by carrying out a simulation of a fluid structure coupled analysis of the upper respiratory tract, surrounding tissues, and air inside the upper respiratory tract accompanying respiration of the test subject.
