Biomedical Image Processing Scaphoids (1mm) MagneVu 1000(MRI)
Biomedical Image Processing • Problems: • Time • Cost factor • Solution: • Correlate X-ray images with 3-D models • Database (typical bones)
Biomedical Image Processing Scaphoid Bones Various shapes and sizes (Zimmer, 1968)

Biomedical Image Processing • Solution: • Superimpose radiographic scan and 3-D model • Select best model from database
Biomedical Image Processing • General Question: • How to combine different modalities?
