An AP large intestine projection with accurate positioning should demonstrate the spinous processes aligned with the midline of the vertebral bodies, indicating no rotation; symmetrical iliac ala, also indicating proper alignment and no rotation; superimposition of the ascending and descending limbs of the colic flexure, showing that the large intestine is correctly visualized; and the fourth lumbar vertebra in the center of the exposure field, ensuring that the relevant anatomy is appropriately captured in the image.
