Deformable 3D-registration and spatiotemporal bilateral filtering were applied to reduce motion and partial-scan artifacts. ...
However, unlike CT, MRI intensity does not have any tissue-specific meaning. Therefore MI-based MR-CT registration may vary from scan to scan as MI depends on the joint histogram of the images. ...
Studies have shown that there is variation in the agreement between operators viewing the same tissue [1] suggesting that a complimentary technique for verification could improve the robustness of the ...
