Which step is NOT part of the standard chest radiography positioning sequence?

In chest radiography, you want the patient positioned so both lungs are visible with minimal distortion or rotation. That means having the patient upright if possible (to promote full inspiration and reduce diaphragmatic elevation), and making sure the trunk is aligned with the midline so the chest isn’t rotated. A neutral head and neck position is also important because turning or tilting the head can subtly change how the trachea and mediastinal structures appear and can affect image quality.

The step about centering the central ray to the midline at the level needed to image the lungs is a technique step that comes after you’ve positioned the patient. It’s part of the exposure setup to ensure the entire lungs are included and the anatomy is captured properly, rather than a positioning action you perform on the patient’s body. So, the head-tilt instruction isn’t part of the standard positioning sequence, whereas upright posture and staying aligned with the midline are. Centering the CR to midline at the appropriate level is a crucial exposure setup step, not a positioning adjustment.
