Current computed tomography (CT) technology allows for near isotropic, submillimeter
resolution acquisition of the complete chest in a single breath hold. These thin-slice chest …

With advances in multidetector-row computed tomography (MDCT), it is now possible to
image the lung in 10 s or less and accurately extract the lungs, lobes, and airway tree to the …

A computational fluid dynamics technique is applied to understand the relative importance of
the upper and intra-thoracic airways and their role in determining central airflow patterns …

Background Patients with severe asthma have increased physiologically measured air
trapping; however, a study using CT measures of air trapping has not been performed. This …

Regional deposition and ventilation of particles by generation, lobe and lung during steady
inhalation in a computed tomography (CT) based human airway model are investigated …

Acute pulmonary embolism causes redistribution of blood in the lung, which impairs
ventilation/perfusion matching and gas exchange and can elevate pulmonary arterial …

The effects of intra-and intersubject variabilities in airway geometry on airflow in the human
lungs are investigated by large eddy simulation. The airway models of two human subjects …

Pulmonary x‐ray computed tomographic (CT) and magnetic resonance imaging (MRI)
research and development has been motivated, in part, by the quest to subphenotype …

Numerous imaging techniques permit evaluation of regional pulmonary function. Contrast-
enhanced CT methods now allow assessment of vasculature and lung perfusion …

The essential function of the lung, gas exchange, is dependent on adequate matching of
ventilation and perfusion, where air and blood are delivered through complex branching …
