Cluster size analysis (D-value) assessment at LAA-950 through the whole lung, RT and LT lobes separately and segments of each lobe and expressed at table, chart and size log–log plot as the cluster sizes were calculated automatically two-dimensionally (as an area [mm2].The different colors express different sizes of the clusters as those less than 1 mm not colored (transparent) (insignificant), blue colored coded for clusters ranges from 1 to 7 mm, green color for cluster size from 7 to 15 mm, and red one for those larger than 15 mm. The log–log plot shows that the steeper the slope, the smaller the cluster size
