For an AP axial chest projection in the lordotic position, the shoulders should be positioned at equal distances from the image receptor (IR) to ensure symmetry, and the patient's back is arched to position the midcoronal plane at a 45-degree angle to the IR, which helps to project the clavicles above the apices of the lungs. The elbows and shoulders are rotated anteriorly to move the scapulae out of the lung fields. A 15-degree cephalad central ray angulation is not used in this position; instead, it's a technique adjustment for when the patient cannot assume the lordotic position, and it's not part of the standard lordotic positioning.
