The proposed method is evaluated on a 49 HRCT cases dataset including various lung disease patterns. The accuracy of the method is assessed using dice similarity coefficient (DSC) and shape differentiation metrics (d mean <\/jats:sub>, d rms <\/jats:sub>), by comparing the outputs of automatic lung segmentations and manual ones. <\/jats:p> The proposed automatic method demonstrates high segmentation accuracy ( DSC = 96.64%, d mean <\/jats:sub> = 1.75 mm, d rms <\/jats:sub> = 3.27 mm) with low variation that depends on the lung disease pattern. It also presents good improvement over the initial lung segmentation (\u0394 DSC = 4.74%, \u0394d mean <\/jats:sub> = -3.67 mm, \u0394d rms <\/jats:sub> = -6.25 mm), including impressive amelioration (maximum values of \u0394 DSC = 58.22% and \u0394d mean <\/jats:sub> = -78.66 mm) when the anatomy-driven algorithm reaches its limit. <\/jats:p> Segmentation evaluation shows that the method can accurately segment lungs even in the presence of disease patterns, with some limitations in the apices and bases of lungs. Therefore, the developed automatic segmentation method is a good candidate for the first stage of a computer-aided diagnosis system for diffuse lung diseases.
