With increasing spatial resolution of regional ventilation and perfusion, it has become more
apparent that ventilation and blood flow are quite heterogeneous in the lung. A number of …

The bronchial, arterial, and venous trees of the lung are complex interwoven structures.
Their geometries are created during fetal development through common processes of …

Abstract Knowledge of the clinical anatomy and function of the respiratory system is
essential for the safe, efficient, and appropriate perioperative management of intubation …

BACKGROUND: Pneumonectomy is a major surgery. Severe hypoxemia sometimes occurs
after pneumonectomy. Effective gas exchange depends on perfect pulmonary ventilation (V˙ …

Anatomically based integrative models of the lung and their interaction with other key
components of the respiratory system provide unique capabilities for investigating both …

Gas exchange, the lung's main function, depends on a tight matching of the distribution of
ventilation and perfusion within any single acinus. Despite the fact that such processes are …

Ventilation imaging using 4D-CT is a convenient and cost effective functional imaging
methodology which might be of value in radiotherapy treatment planning to spare functional …

Recent treatment planning studies have demonstrated the use of physiologic images in
radiation therapy treatment planning to identify regions for functional avoidance. This image …

Les systemes biologiques sont des systemes complexes par leur géométrie et/ou leur
fonctionnement. Dans la tres grande majorité des cas, on peut les assimilera des systemes …
