Where should the central ray be directed for a lateral calcaneus radiograph?

For a lateral calcaneus radiograph, the central ray should be directed to the mid-calcaneus. This positioning is critical because it ensures that the anatomical details of the calcaneus (heel bone) are accurately depicted on the radiograph. To achieve a clear image, it's important to focus on the central area of the calcaneus, as this allows for proper visualization of its structures, including the sustentaculum tali, which is often evaluated for pathology.

Directing the central ray at the mid-calcaneus effectively captures the lateral projection, providing radiologists with essential information for diagnosis, such as fractures or other abnormalities. This positioning is standardized in radiographic protocols for lateral views of the foot and ankle, ensuring consistency and reliability in imaging.
