Final answer:
The CR is angled cephalically at 15 degrees for an AP axial image of the toes.
Step-by-step explanation:
When imaging the toes, the CR (Central Ray) is angled for the AP axial image. The correct answer is C. 15 degrees. The CR is angled cephalically at 15 degrees, or 10 degrees if the patient cannot tolerate the full 15-degree angulation. This angulation allows for better visualization of the metatarsophalangeal (MTP) joints and provides more accurate measurements.
