Question: 1 / 1100

On the 15-degree occipitofrontal projection, which cranial bone is best demonstrated?

Frontal Bone

The 15-degree occipitofrontal projection is specifically designed to optimize visualization of the frontal bone. This projection helps to reduce the superimposition of the parietal bones over the frontal bone, allowing for a clearer outline and better anatomical detail of the frontal region of the skull. The angle of 15 degrees directs the central ray toward the forehead, enhancing the contrast between the frontal bone and surrounding structures.

The positions of the other cranial bones in this projection are either less prominent or more obscured due to their anatomical arrangement and the way the X-ray beam intersects the skull. Thus, while the other bones may still be somewhat visible, it is the frontal bone that is most favorably depicted in this particular projection, making it the best demonstrated cranial bone during this imaging technique.
