Image Receptor and Patient Placement
The image receptor is placed in front of the patient, perpendicular to the midsagittal plane and parallel to the coronal plane. The patient’s head is tilted downward so that the canthomeatal line forms a 25-degree to 30 degree angle with the image receptor. To improve the visualization of the condyles, the patient’s mouth is opened, so that the condylar  heads are located inferior to the articular eminence. When requesting this image to evaluate the condyles, it is necessary to specify “open-mouth, Reverse-Towne”; otherwise, a standard Towne view of the occiput may result.
Position of Central X-Ray Beam
The central beam is perpendicular to the image receptor and parallel to the patient’s midsagittal plane and is centered at the level of the condyles.
Resultant Image 
The midsagittal plane (represented by an imaginary line extending from the middle of the foramen magnum and the posterior arch of the atlas through the middle of the bridge of the nose and the nasal septum) should divide the skull image in two symmetric halves. The petrous ridge of the temporal bone should be super-imposed at the inferior part of the occipital bone, and the condylar heads should be projected inferior to the articular eminence.
