"With volumetric scans becoming standard, and many CT scanners no longer being able to tilt, the whole head is scanned, and then axial images are reconstructed at any desired angle. As such many departments are switching the standard axial CT brain plane to be aligned with the AC-PC line which is standard in MRI 2,3. Interestingly, this plane is quite close to the original orbitometal line and to the plane of the planum sphenoidale and hard palate."
