The plantodorsal projection of the calcaneus is best described as which type of projection?

Explanation:
The plantodorsal projection is an axial view of the calcaneus, where the x‑ray beam enters the plantar (bottom) surface of the foot and exits through the dorsum, directed along the long axis of the calcaneus. This orientation lines up the beam with the bone itself, giving a clear view of the calcaneal body and subtalar joint with minimal foreshortening and superimposition. It contrasts with lateral or AP/dorsoplantar views, which are not angled along the calcaneus’s axis.
