Answer to Question 1

filtration

Rationale: X-ray beams are polyenergetic. In efforts to remove the low energies from the beam that contribute to patient skin dose, filtration is necessary.

Answer to Question 2

the talocalcaneal joint is open and the tuberosity is sufficiently demonstrated

Rationale: The plantodorsal axial represents the talocalcaneal joint open. The entire calcaneus is demonstrated with sufficient density from the joint space to the tuberosity.
