Figure 4: Coronal (a) and sagittal (b) two-dimensional sections passing through the C1-C2 joint of overlapped three-dimensional images with and without the cartilage (soft tissue) with the black line delineating the bone and the red line marks the cartilage (soft tissue). Bony articular surface of C1 is concave both in coronal and sagittal plane (green arrow), whereas for C2, it is concave in sagittal plane (green arrow) and has a medial convexity (orange arrow) with lateral concavity (green arrow) in coronal plane. The cartilages of C1 and C2 are biconvex in both sagittal and coronal planes
