What is the correct tube angulation for a plantodorsal axial calcaneus radiograph?

Explanation:
Align the X-ray beam with the long axis of the calcaneus to obtain a true axial view that clearly shows the subtalar joint and posterior facet. A cephalad tilt of about 40 degrees from horizontal directs the beam along that axis when the foot is dorsiflexed, minimizing superimposition and foreshortening. Angles much smaller or in the opposite direction would misalign the beam, leading to distortion or obscured anatomy.
