Implementation Considerations

• Requires expertise in medical imaging, 3D surface processing, and kinematic analysis.
• Depends on 4D CT scanners, DICOM-compatible software, and open-source registration tools (e.g., iterative closest-point algorithms).
• Necessitates cross-team standardization between imaging, biology, and bioinformatics units for consistent surface labeling and landmark selection.
• Involves adaptation considerations across model systems due to variations in bone size, joint complexity, and motion range.
• Limited by motion artifacts in fast or large-scale movements, as noted in the source material.
