Lung Modeling: Integrating Anatomy and Physiology
Jonathan Kaye, Dimitri Metaxas, John R. Clarke, Bonnie Webber · 2007
We present an integrated approach between anatomical and physiological modeling that is useful in medical training and visualization of internal body organ function. In particular, we model the breathing mechanism in the respiratory system because it involves physiological change, such as gas exchange, that depends on gross anatomical deformations (volume changes). We describe our initial model of the lungs for a simplified process of normal, quiet breathing. Our system consists of two integrated levels of abstraction: (i) geometric and physics-based modeling (shape extraction, motion, deformations, and graphical rendering); (ii) mathematical relationships among parameters that express physical laws and physiological processes. We present experiments that demonstrate graphically the organ geometry, physics, and physiological dynamics. 1 Introduction With advances in computer graphics and faster hardware, computers are becoming an increasingly important tool for visualizing medical da...
