Question

Quizplus · Accepted Answer

The decubitus position requires a recumbent body position (lying down) and a horizontal CR (central ray). In this position, the patient lies on their side with the CR parallel to the floor. This position is useful for demonstrating air-fluid levels in the abdomen or thorax. The supine position requires a horizontal CR but the patient is lying on their back. The prone position requires a horizontal CR and the patient is lying on their stomach. The recumbent position is a general term for any lying down position and does not specify the CR orientation.
