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.
