What relational term is used if a radiographic projection employs a superior tube angle?

What relational term is used if a radiographic projection employs a superior tube angle?

• A. Distal
• B. Caudal
• C. Cephalic
• D. Proximal

Answer: (C)

Cephalic describes a direction toward the head. When the radiographic tube is angled superiorly, the X-ray beam is directed toward the head, so the projection is cephalad (cephalic). Distal and proximal refer to positions along a limb and aren’t used for describing beam angulation, while caudal means toward the feet or tail—opposite of the superior direction.
