Planes Information
Axis = a line from the bottom of the feet to top of the head.
Transaxial plane is perpendicular to the axis and shows left and right, anterior and posterior as seen from below. It is the plane used most often for CT scans of the brain and for all of the images shown in this web site.
Coronal plane shows left and right, superior and inferior as seen from in front. It is often useful for CT scans of the sella and pituitary gland and paranasal sinus areas. Click for an example in another website.
Sagittal plane shows anterior to posterior, superior and inferior as seen from the side. Rarely used for CT scans of the brain but is often used for spinal imaging and for MRI of the brain. Link to some sagittal views in another website.
