For the RAO or PA upper GI projection and/or position on a sthenic body type of patient, the CR and image receptor should be centered at the level of L1. This is approximately 1-2 inches (2.5-5 cm) above the lower costal margin and 1 inch (2.5 cm) above the xiphoid process. It is important to center at this level so that the stomach and duodenum are captured in the image without significant overlap, and to avoid excessive magnification or distortion of the anatomy.
