Figure 3.14: Voxel similarity measures for rigid body and warping registration.
Correlation coefficient (CC) (a) and mutual information (MI) (b) following regis-
tration with (light bars) and without (dark bars) warping are plotted. Conditions
described in Experimental Methods are listed on the
x
-axis. Warping increase
CC and MI in all cases. The most significant increases occurred in the case of the
treatment-diagnosis volume pairs where maximum increase in CC and MI are
101.7% and 87.8%, respectively. For volumes acquired within the same diagnostic
position and comparable conditions (two right-most groups), warping did not
have significant improvement over rigid body method.
