Medicinsk billeddannelse er ofte afhængig af CT-scanninger til detaljerede 3D-rekonstruktioner, men disse er kostbare og udsætter patienter for højere stråling. Standard røntgenbilleder er mere tilgængelige, men mangler dybdeinformation. AI-algoritmer kunne potentielt udlede 3D-bonemodeller fra 2D-røntgenbilleder, hvilket ville forbedre diagnostisk nøjagtighed uden yderligere billeddannelse.
Background
Medical imaging often relies on CT scans for detailed 3D reconstructions, but these are costly and expose patients to higher radiation. Standard X-rays are more accessible but lack depth information. AI algorithms could potentially infer 3D bone models from 2D X-rays, improving diagnostic accuracy without additional imaging.
Current AI systems can reconstruct coarse 3D bone shapes from two or more standard X-ray images by using deep-learning models trained on large datasets of paired X-ray and CT volumes. Accuracy is highest for dense cortical bone and decreases for trabecular bone and small features, and the approach is primarily used for surgical planning and follow-up rather than definitive diagnostics. Research prototypes show promise for single-view methods under limited angles, yet these still lag behind multi-view accuracy and require specialized calibration.
