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

Figure 7

Typical en face images for the ultrasound and micro-CT imaging. (a) MIP images of the ultrasound imaging with different VOI thickness: 15, 45, 105, and 150 μm, respectively. (b) MIP images of the micro-CT imaging with different VOI thickness: 21, 42, 105, and 147 μm, respectively. The ultrasound scanning direction (arrow) is indicated in the last images of (a) and (b) for the reference of comparison. The rectangular box in (b) indicates the region of ultrasound imaging. The scale bar is 1 mm in length.
