Fig. 3From: Quantitative CT-based image registration metrics provide different ventilation and lung motion patterns in prone and supine positions in healthy subjectsDemonstration of regional lung motionography in supine and prone positions. Displacement vectors from expiration to inspiration (a and b) and normalized 3D displacement magnitude maps on entire lung regions (c and d) in supine position (a and c) and prone position (b and d). For visual interpretation, three-dimensional displacement vectors were plotted and colored according to a rainbow scale by s*Back to article page
