When to use
Common Conversion Paths
| Path | Typical use | Main risk |
|---|---|---|
| DICOM -> NIfTI | AI training, neuroimaging, segmentation pipelines | Losing orientation, spacing, or series metadata if conversion is careless |
| NIfTI -> DICOM | Returning AI/processed volumes into viewer/PACS-like workflows | DICOM metadata must be rebuilt carefully; not always PACS-ready |
| NIfTI/DICOM -> STL | 3D printing, surgical planning, implant planning, anatomy meshes | Requires segmentation before mesh export; surface smoothing can distort anatomy |
| STL -> DICOM/NIfTI | Registration, planning overlays, mesh-to-volume workflows | Rasterization loses mesh precision and requires a target voxel grid |
