The orbitomeatal line (OML) runs from the nasion through the outer canthus of the eye to the center of the external auditory meatus. The infraorbitomeatal line (IOML) runs from the inferior orbital margin to the upper border of the external auditory meatus.

Mar 7, 2014 · Adjust head until Lips Meatal Line (LML) is perpendicular; Orbitomeatal Line (OML) forms a 55 degree angle with the IR. Position Mid Sagital Plane (MSP) perpendicular to the middle of the grid or the table or upright bucky surface.

OML: Orbitalmeatal Line – There is an 8 degree difference between the GML and the OML IOML: Infraorbitomeatal Line – AKA Reid’s Base Line – There is a 7 degree difference between the OML and the IOML Skull Baselines:

Orbitomeatal Line (OML) forms a 55 degree angle with the IR. Align Central Ray perpendicular, centered to exit at acanthion. • PA Caldwell - the orbitomeatal line is running perpendicular to the detector. The central ray is angled caudad around 15° to exit at the nasion. • AP Towne - the OML perpendicular to the image receptor. The

A radiograph of a posteroanterior (PA) axial projection (Caldwell method) of the cranium reveals that the petrous ridges are located at the level of the lower one third of the orbits. The technologist performed this projection with the CR angled 15°caudal to the orbitomeatal line (OML).

Lateral Skull Projection: Describe the positioning of the patient and equipment for this position. With side of interest closest to the IR, place patient with chest oblique towards the board. Turn patients head to true lateral position. Adjust neck flexion so the IOML is parallel to the IR, while it is perpendicular to the front edge of the IR.

Orbitalmeatal line (OML) of the eye and auditory meatus (EAM). Line that connects the infraorbital margin and. the external auditory meatus (EAM). It is also. 15. Infraorbitmealtal line. referred to as the Reid's base line of the (IOML) cranium. Line that connects the pupils of the eye. In a. true lateral position, the IPPL must be. 16.
