3D High-Frequency Ultrasound Imaging of Cartilage-Bone Interface Compared with Micro-CT

<div>(a) Registration of two tidemark surfaces obtained from the ultrasound (gray) and micro-CT (green) imaging. The white arrow shows the direction of the inserted metal pin. (b) Clouds/mesh distance mapping for ultrasound obtained tidemark surface to that from micro-CT after registration. Shown on the right is the color bar used for distance mapping in unit of mm.
