Answer to Question 1

plantodorsal axial

Rationale: Plantodorsal axial is used for the calcaneus. The tube is angled 40 degrees cephalic and directed to the base of the 3rd metatarsal on the plantar surface of the foot.

Answer to Question 2

The patient is supine with affected arm left in neutral position and closest to the image receptor. The unaffected arm is elevated above the head.

Rationale: A transthoracic lateral can be positioned either supine or upright depending on patient condition. The affected side should be positioned closest to the image receptor, and left in the neutral position. The unaffected arm is elevated above the patient's head. Ensure no rotation of the thorax. The central ray exits the level of the surgical neck and passes through the level of MCP or slightly posterior.
