What is the tube tilt angle for an AP foot X-ray?

For an AP foot X-ray, the correct tube tilt angle is generally 10-15° cephalad. This angle is necessary to effectively align the X-ray beam with the anatomical structures of the foot, which can help reduce distortion and provide a clearer image for diagnostic purposes. When the tube is angled cephalad, it minimizes the overlap of bones in the foot, allowing for better visualization of the tarsal bones as well as the metatarsals.

Using a cephalad angle helps in compensating for the natural arch of the foot, ensuring that important anatomical details are captured in the radiograph, which is crucial for accurate assessment. The specified range of 10-15° cephalad is a standard practice in radiography for this particular view, ensuring consistent results across different patients and situations.
