Coordinate system. (a) Origin of the coordinate system was observed from top view. (b) Origin was observed from lateral view. (c) X and Y axes were perpendicular to sagittal and coronal planes. (d) Y and Z axes were perpendicular to coronal and transverse planes. (e) X and Z axes were perpendicular to sagittal and transverse planes.
