Figures

Image of FIG. 1.
FIG. 1.

Laparoscopic orientation (left) of kidney phantom to resemble surface seen by surgeons during a laparoscopic partial nephrectomy. Cradle constructed to provide the open orientation (right) of kidney phantom to resemble surface seen by surgeons during an open partial nephrectomy.

Image of FIG. 2.
FIG. 2.

Second segmentation of kidney surface in laparoscopic orientation. Each gray value corresponds to a different surface subset. The numbers represent the percentage of the total image surface used in the registration.

Image of FIG. 3.
FIG. 3.

Segmentation of kidney surface in open orientation.

Image of FIG. 4.
FIG. 4.

Example of the transformation of the initial pose caused by perturbation vector with magnitudes of 5, 15, and .
