4. Results  Case1(For Left Bone)

5. Results  Segmentation for Left Bone  Threshold: 150~1300  Seed Point(x,y,z) = (95,310,6) Image Subtraction 3D region growing Local registration Global resample

6. Results  After Local Registration  Get Translation (x,y,z) = (2.349893, 0.578654, 0.603175) Image Subtraction 3D region growing Local registration Global resample Non-RegistrationRegistration

7. Results  Global Resample Image Subtraction 3D region growing Local registration Global resample

8. Results  Case2(For Middle Bone)

9. Results  Segmentation for Middle Bone  Threshold: 195~1000  Seed Point(x,y,z) = (275,325,6)  ) Image Subtraction 3D region growing Local registration Global resample

10. Results  After Local Registration  Get Translation (x,y,z) = (2.600811, -1.314565, 0.857548) Image Subtraction 3D region growing Local registration Global resample Non-Registration Registration

11. Results  Global Resample Image Subtraction 3D region growing Local registration Global resample

12. Results  Case3(For Right Bone)

13. Results  Segmentation for Right Bone  Threshold: 150~1200  Seed Point(x,y,z) = (445,325,6) Image Subtraction 3D region growing Local registration Global resample

14. Results  After Local Registration  Get Translation (x,y,z) = (2.506265, -1.402524, 2.504027) Image Subtraction 3D region growing Local registration Global resample

15. Results  Global Resample Image Subtraction 3D region growing Local registration Global resample

16. Translation(x,y,z) = (2.349893, 0.578654, 0.603175) Translation(x,y,z) = (2.600811, -1.314565, 0.857548) Translation(x,y,z) = (2.506265, -1.402524, 2.504027) Source

17. Problem

18. Conclusion  Rigid Registration  not suitable for this case  Select Middle Region to Do Registration  Suitable for Brain

19. Conclusion  Using Non-Rigid Registration (Deformable)  Point Set Registration  And Use Three Translations : A,B, and C
