Changes in the shape of the lung during breathing determine the movement of airways and alveoli, and thus impact airflow dynamics. Modeling airflow dynamics in health and disease is a key goal for predictive multiscale models of respiration. Past eff

Pulmonary computational fluid dynamics models require that three-dimensional images be acquired over multiple points in the dynamic breathing cycle without breath holds or changes in ventilatory mechanics. With small animals, these requirements can r

In this work, we compare two methods for evaluating and quantifying pulmonary airspace enlargement in a mouse model of chronic cigarette smoke exposure. Standard stereological sample preparation, sectioning, and imaging of mouse lung tissues were per

Recent years have seen a substantial increase in the application of machine learning (ML) for automated analysis of nondestructive examination (NDE) data. One of the applications of interest is the use of ML for the analysis of data from in-service i

Anomaly Detection and Imaging with X-Rays (ADIX) VI.
Gratings-based phase contrast X-ray imaging provides additional materials signatures in textured media based on the deflection of the X-ray beam. Using this technique with a hard (~160 kVp) X-ray spectrum has shown potential for improved materials di

Anomaly Detection and Imaging with X-Rays (ADIX) IV.
Gratings-based x-ray imaging can provide additional materials signatures, including refraction which is proportional to variations in electron density, and scatter which is sensitive to sub-resolution texture. Phase contrast measurements have been co

Three-dimensional computational fluid dynamics and Lagrangian particle deposition models were developed to compare the deposition of aerosolized Bacillus anthracis spores in the respiratory airways of a human with that of the rabbit, a species common

The rabbit is commonly used as a laboratory animal for inhalation toxicology tests and detail knowledge of the rabbit airway morphometry is needed for outcome analysis or theoretical modeling. The objective of this study is to quantify the morphometr
