An imaging direction, downwards relative to the long axis of the human body.

A tomographic imaging plane, parallel to the ground, perpendicular (rotated 90°) to the long axis of the human body; the axial plane separates the superior from the inferior part (the head from the feet). Also called transaxial, transversal, transverse plane.
