In the Swimmer's View positioning, which arm is moved forward?

In the Swimmer's View positioning, the technique is utilized primarily to obtain radiographs of the cervical spine and upper thoracic region, particularly when the patient presents challenges in achieving a standard lateral view due to restrictions in arm positioning or body habitus. The arm closest to the bucky, which typically is the down side arm, is moved forward in order to minimize its interference with the imaging area while simultaneously positioning the far side arm back to open up the thoracic area.

By moving the arm closest to the bucky forward, the radiologic technologist ensures that the anatomical structures of interest—the cervical spine and the first few thoracic vertebrae—are better visualized without the obstruction of the shoulder and arm closest to the film. This position allows for clearer imaging, effectively reducing superimposition and enhancing diagnostic capabilities.
