In an AP projection of the clavicle, how many degrees is the CR typically angled?

In an AP projection of the clavicle, the central ray (CR) is typically angled between 15 to 30 degrees cephalad to properly visualize the clavicle and its anatomical details. This specific angling helps to avoid superimposition of the clavicle over the thoracic structures and provides a clearer image of the bone. The cephalad angle also helps to project the clavicle into a more lateral position on the imaging receptor, making important anatomical features more discernible.

Using this range ensures optimal visualization of the clavicle's length and curvature, promoting accurate diagnosis and assessment of any potential injuries or conditions affecting this area. This angle is recognized as standard practice in radiographic techniques for obtaining the best possible images of the clavicle in relation to the surrounding anatomical structures.
