What should be the tube tilt setting for an AC joint x-ray?

For an AC joint x-ray, the tube tilt setting is typically set at 5-10° cephalad. This angle is particularly important for visualizing the acromioclavicular joint by allowing for a clear separation of the joint structures and reducing the superimposition of adjacent anatomy.

Employing a cephalad tilt helps to align the x-ray beam perpendicular to the joint space, which enhances the visibility of any potential joint pathology or displacement. It also aids in obtaining a better image quality by reducing potential artifacts caused by surrounding tissues.

Understanding this specific positioning is crucial for radiologic technologists, as it directly influences the diagnostic quality of the x-ray images, ultimately impacting patient care and treatment decisions.
