鼻科医生经常面临着从功能角度评估鼻呼吸以获得有效治疗干预的挑战。虽然复杂的鼻腔解剖结构可以通过目视检查和医学成像来显示，但关于鼻腔气流本身只有模糊的信息：鼻压计提供了关于压力梯度以及总流量和鼻腔流动阻力的非特异性整体信息。在这篇文章中，我们演示了如何通过模拟和可视化分析鼻气流，基于人体上呼吸道的解剖学正确模型，可以提高对生理性鼻呼吸的理解。特别是，我们演示了如何各种信息可视化（InfoVis）技术，如高度可扩展的实施平行坐标，时间序列可视化，以及非结构化网格多体积渲染，所有集成在一个多链接视图框架，可以用来获得更深入的了解鼻呼吸。评价是通过对时空气流特性的视觉探索来完成的，时空气流特性不仅包括关于流动特征的信息，而且还包括关于伴随的量，例如温度和湿度。据我们所知，这是在考虑鼻气道的完整模型、现实边界条件和所有物理相关的时变量的情况下，在几个模拟呼吸周期内对鼻子的生理功能进行的第一次深入的视觉探索。
Rhinologists are often faced with the challenge of assessing nasal breathing from a functional point of view to derive effective therapeutic interventions. While the complex nasal anatomy can be revealed by visual inspection and medical imaging, only vague information is available regarding the nasal airflow itself: Rhinomanometry delivers rather unspecific integral information on the pressure gradient as well as on total flow and nasal flow resistance. In this article we demonstrate how the understanding of physiological nasal breathing can be improved by simulating and visually analyzing nasal airflow, based on an anatomically correct model of the upper human respiratory tract. In particular we demonstrate how various information visualization (InfoVis) techniques, such as a highly scalable implementation of parallel coordinates, time series visualizations, as well as unstructured grid multi-volume rendering, all integrated within a multiple linked views framework, can be utilized to gain a deeper understanding of nasal breathing. Evaluation is accomplished by visual exploration of spatio-temporal airflow characteristics that include not only information on flow features but also on accompanying quantities such as temperature and humidity. To our knowledge, this is the first in-depth visual exploration of the physiological function of the nose over several simulated breathing cycles under consideration of a complete model of the nasal airways, realistic boundary conditions, and all physically relevant time-varying quantities.
