CAMRT Radiography Practice Exam

What is the tube position for an "outlet" pelvis in males?

1. 15 - 25 degrees cephalad

2. 20 - 35 degrees cephalad

3. 30 - 45 degrees cephalad

4. 45 - 60 degrees cephalad

The correct answer is: 20 - 35 degrees cephalad

The appropriate tube position for an "outlet" pelvis projection in males is typically 20 to 35 degrees cephalad. This range is specifically designed to project the X-ray beam at an angle that optimally visualizes the pelvic outlet, allowing for better assessment of anatomical structures such as the pubic symphysis and the ischial tuberosities. Positioning the tube within this range helps to reduce spatial distortion of the pelvic anatomy while ensuring that important detail is captured in the image. The selected angle accounts for the male pelvis's anatomical differences compared to the female pelvis, where a different projection angle may be used. This understanding of anatomy and precise imaging techniques is crucial for obtaining diagnostic quality radiographs in clinical practice.
