Evaluation of Deformable Image Registration for Three-Dimensional Temporal Subtraction of Chest Computed Tomography Images

Figure 4

Volume change tracker for Figure 3 showing that lesion shrinkage changes with six successive slices in the three planes. The regions around the green lines show changes in warped moving and fixed images. (a), (b), and (c) Lesion in the axial, sagittal, and coronal planes. The above row shows the lesion in warped moving images, while the below row shows the lesion in fixed images. Clear shrinkage of the lesion is noted in the fixed image (0.65%) when compared with that in the warped moving image.
