Normalizing computed tomography data reconstructed with different filter kernels: effect on emphysema quantification

Objectives To propose and evaluate a method to reduce variability in emphysema quantification among different computed tomography (CT) reconstructions by normalizing CT data reconstructed with varying kernels. Methods We included 369 subjects from the COPDGene study. For each subject, spirometry and...
