Improvement of Registration Accuracy with Anatomical Landmarks
- Most surgical navigation systems use the surface information for the registration.
- They use skin markers for the registration, but the markers far from target area.
- Even though the fiducial registration error (FRE) is small, target registration error (TRE) can be high.
- Including anatomical landmarks near the target can reduce the TRE.
- In our system, anatomical landmarks are obtained and used by ultrasound image.
