Interactive deformable registration with landmarks
Radial Basis Functions
- TPS (global support)
- Wendland (local support)
- Gaussian (global support with variable kernel width, allowed for local regularization)
Areas of application
• local details of the image, primarily the details of low contrast
• anatomic changes – tumor shrinking– weight loss
• gross body movement– breathing– position variation
• substantial volume change– full vs empty bladder or rectum
Misalignment caused by anatomic changes
Misalignment caused by position variation
Misalignment caused by position variation
Misalignment caused by the rectum enlargement
