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

Figure 3

A schematic showing the processing of ultrasound and micro-CT imaging data to obtain a 3D tidemark surface and en face imaging of the cartilage-bone interface. 3D surface is obtained by connecting all the surface lines extracted from each ultrasound/micro-CT image in scan sequences. En face image is obtained by projecting data in a certain thickness region beyond the tidemark.
