When imaging the left scapula with the LAO position, where is the central ray directed?

Question

to enter mid lateral border
to exit the glenohumeral joint
to enter mid vertebral border
to enter mid axillary border

Answer 1

to enter mid vertebral border

Rationale: Upright lateral scapula will allow the affected scapula to be closer to the image receptor. The patient is rotated until the lateral and medial borders of the scapula superimpose. When upright, the central ray will enter the mid vertebral border and exit the lateral border. When supine, the central ray will enter the mid axillary border and exit the vertebral border.
