An AP axial chest projection (lordotic position) with poor positioning demonstrates the clavicles within the lung apices. How should the positioning setup be adjusted for an optimal image to be obtained?
1)Increase the degree of cephalic central ray angulation.
2)Anteriorly rotate the elbows and shoulders.
3)Arch the patient's back more, increasing the midcoronal plane to IR angle.
4)Position the patient's feet closer to the IR.
A) 1 and 3 only
B) 2 only
C) 1, 2, and 3 only
D) 1, 2, 3, and 4

1) Increasing the degree of cephalic angulation will move the clavicles down and out of the lung apices.
3) Arching the patient's back more will increase the distance between the clavicles and the lung apices.

Option 2 (Anteriorly rotate the elbows and shoulders) is incorrect because it would not affect the position of the clavicles within the lung apices.
Option 4 (Position the patient's feet closer to the IR) is incorrect because it would not affect the position of the clavicles within the lung apices.
