CAMRT Radiography Practice Exam

Which projection technique best visualizes the frontal bone?

1. 15-degree occipitofrontal projection

2. Lateral projection

3. AP projection

4. Tangential projection

The correct answer is: 15-degree occipitofrontal projection

The 15-degree occipitofrontal projection is the preferred technique for visualizing the frontal bone, primarily because it provides a detailed view that highlights the contours and features of this area. This projection involves angling the central ray 15 degrees from the occipital region toward the frontal bone, effectively reducing superimposition from other structures and enabling clearer visualization. By using this specific projection technique, radiographers can obtain a more accurate representation of the frontal bone, which is crucial for diagnosing any potential pathologies or injuries associated with that area. In contrast, while other projections such as lateral and AP may show the frontal bone, they are not specifically designed to accentuate its details as effectively as the occipitofrontal projection. The tangential projection is typically not used for frontal bone visualization, as it is better suited for assessing regions like the nasal bones or zygomatic arches. Overall, the targeted approach of the 15-degree occipitofrontal projection provides the best clarity and detail for evaluating the frontal bone.
