Project Synopsis
| The overall objective of this research is to
develop state-of-the-art, biologically-based
computational models of the respiratory system
that couples high-performance supercomputing with
the latest imaging and experimental
advances. Using an interdisciplinary
bioengineering approach, we hope to achieve an
unprecedented level of detail in describing
structure-function relationships in the
respiratory system of laboratory animals and
humans. Our underlying philosophy centers on the
belief that highly detailed biologically based
computational models provide a unique basis for
integrating fundamental information about the
mammalian respiratory system into a quantitative,
understandable format that can readily be
interrogated to gain important new insights into
how interactions with the environment ultimately
affect both normal and potentially sensitive
individuals. |

Reconstructed Airway Tree
| Magnetic resonance imaging of hyperpolarized 3-He
was used to create this 3D image of an airway
tree. The imaging was done on a live,
mechanically ventilated, 310 g rat. The airway
tree is rotated such that the trachea is vertical,
as if the rat was standing on his hind legs. |
