What is the appropriate tube tilt for a lateral coccyx x-ray?

• A. 0°
• B. 5-10° caudal
• C. 5-10° cephalad
• D. 15-20° lateral

Answer: (C)

The appropriate tube tilt for a lateral coccyx x-ray is typically between 5-10 degrees caudal. This angle is used to project the x-ray beam downward toward the coccyx while minimizing superimposition from surrounding anatomical structures. By angling the tube in this manner, the coccyx is better visualized in profile, allowing for clear imaging that can assist in the diagnosis of fractures or other pathologies in that area. In a lateral view, the goal is to ensure that the coccyx is distinctly captured without overlap from adjacent pelvic structures. The chosen caudal angle achieves this by directing the x-ray beam in a way that aligns the coccyx with the image receptor, producing optimal image quality. Other angles, such as cephalad, would not provide the necessary perspective for a lateral coccyx view, as they would result in an image that may be distorted or lacks clarity on the anatomical details of the coccyx. A lateral angle focus is also not appropriate as it does not conform to standard practices for this specific imaging.
