Figure 4

Correlation (left panels) and agreement (right panels) between volumes of aliquots (V_aliq) calculated using Lungview^® and measured from lung weight after instillation of lung water (upper panels) and a solution containing 5% of contrast material (lower panels) into the human lung phantom. In the left panels, the dotted line represents the identity line and the solid line represents the linear regression line. In the right panels, the solid line represents the difference between calculated (using Lungview^®) and measured (actual) aliquots (bias), and the dotted lines represents 2 SD (precision of the bias, according to the Bland–Altman method).
