Figure 3

Comparison of the alignments of large lung lesions after DIR. Columns from left to right are the axial, sagittal, and coronal planes. The white arrows indicate lesions in the left lung. (a) Moving images (long and short diameters = 71 and 52 mm, resp.). (b) Fixed images (interval of 3 months 20 days; long and short diameters = 49 and 31.5 mm, resp.). (c) Warped moving images (long and short diameters = 55 and 36.8 mm, resp.). (d) Log-Jacobian image of the deformation field. (e) Subtraction images.
