A technique for visualization and mapping of local cartilage thickness changes in MR images of osteoarthritic knee

The registration accuracy was 0.93 ± 0.05 mm (less than a voxel of magnetic resonance data). Local cartilage thickness changes were seen as having follow-up clinical study for detecting local changes in cartilage thickness. Experiment results suggest that our method was sufficiently accurate and effective for monitoring knee joint diseases.
