STEREOTACTIC PLANNING
- MRI + CT fusion: from image space to stereotactic space
- 1 MRI — High-resolution anatomy
- 2 AC–PC — Define reference frame
- 3 CT — Stereotactic coordinates
- 4 FUSION — Rigid registration
- 5 TARGET — Nucleus / pathway
- 6 TRAJECTORY — Safe entry → target
- REGISTRATION ERROR = TARGETING ERROR
- Always inspect fusion quality before trusting a coordinate.
- Targeting principles: contemporary DBS stereotactic imaging and surgical planning literature.
