FIG. 1.

The region of interest for the 3D/3D registration of pelvic images.

Image of FIG. 2.
FIG. 2.

The frequency of reversibility errors for the MSD similarity measure. Notice the separate grouping of and .

Image of FIG. 3.
FIG. 3.

(a) The reversibility error versus the difference in the forward and the reverse similarity measures at convergence. (b) The reversibility error versus the average of the forward and the reverse similarity measures at convergence.

Image of FIG. 4.
FIG. 4.

Similarity measures as functions of shifts in the left/right and anterior/posterior axes (unit: mm) when no intensity threshold was applied. 3D surface plots are shown in the left column and contour plots the right column. The similarity measures are (a) negated MSD, (b) NMI, and (c) MMI.

FIG. 5.

Similarity measures as functions of shifts in the left/right and anterior/posterior axes (unit: mm) when bony landmark threshold was applied. 3D surface plots are shown in the left column and contour plots the right column. The similarity measures are (a) negated MSD, (b) NMI, and (c) MMI.
