“Density mask”: an objective method to quantitate emphysema using computed tomography

NL Müller, CA Staples, RR Miller, RT Abboud - Chest, 1988 - Elsevier
We used a computed tomography (CT) scanner program (“density mask”) that highlights
voxels within a given density range to quantitate emphysema by defining areas of abnormally …
