Accurate measures of regional lung air volumes from chest X-rays of small animals [PDF]
, 2022 We present a robust technique for calculating regional volume changes within the lung from X-ray radiograph sequences captured during ventilation, without the use of computed tomography (CT). This technique is based on the change in transmitted X-ray intensity that occurs for each lung region as air displaces the attenuating lung tissue.

Automated Estimation of Total Lung Volume using Chest Radiographs and Deep Learning [PDF]
, 2021 Total lung volume is an important quantitative biomarker and is used for the assessment of restrictive lung diseases. In this study, we investigate the performance of several deep-learning approaches for automated measurement of total lung volume from chest radiographs.

Air pollution and airway resistance at age 8 years - the PIAMA birth cohort study. [PDF]
, 2018 Air pollution has been found to adversely affect children's lung function. Forced expiratory volume in 1 s and forced vital capacity from spirometry have been studied most frequently, but measurements of airway resistance may provide additional ...

Measurement of the Pressure-volume Curve in Mouse Lungs [PDF]
Journal of Visualized Experiments, 2015 In recent decades the mouse has become the primary animal model of a variety of lung diseases. In models of emphysema or fibrosis, the essential phenotypic changes are best assessed by measurement of the changes in lung elasticity. To best understand specific mechanisms underlying such pathologies in mice, it is essential to make functional ...

Quantification of lung function on CT images based on pulmonary radiomic filtering [PDF]
, 2021 Purpose: To develop a radiomics filtering technique for characterizing spatial-encoded regional pulmonary ventilation information on lung CT. Methods: The lung volume was segmented on 46 CT images, and a 3D sliding window kernel was implemented across the lung volume to capture the spatial-encoded image information.
