【摘要】 基于志愿者CT医学图像,用表面重建的方法对人体上呼吸道进行三维重建并用有限元方法对整个腔体中的气体流动进行数值模拟及分析。从数值模拟结果可以得到人体呼吸过程中气体流场在整个腔体中的分布。所建模型较真实的反映了实际解剖结构形态,数值模拟结果对临床上呼吸道解剖结构与功能相关疾病的诊断、发病机理的深入探讨具有参考价值。更多还原

【Abstract】 Based on CT medical images of volunteers, a 3D model of upper airway was reconstructed by the method of surface rendering. And numerical simulation was performed for the airflow in the whole cavity using the FEM. From the results of the numerical simulation, the airflow distribution in the whole cavity in the course of respiration was obtained. It is comparatively true that the established model reflects the real anatomical configuration, the results of the numerical simulation is useful for studying the pathogenesis and diagnosing the disease which relate to the anatomical structure and function of upper airway.更多还原
