Lung Density Analysis - Functional

Lung Density Analysis™ applies big data analysis to paired inspiratory / expiratory chest CT studies to provide visualization and quantification of lung regions with abnormal tissue density. Functional LDA is an automated image analysis providing a mapping of normal lung, air-trapping and areas of persistent low density (< -950 HU, which may be indicative of emphysema in a combined image to help visualize the components of COPD. LDA provides a full 3D DICOM series with density overlays and a quantitative report of density categories by lung region.
