What is the correct procedure for setting up the tube tilt in a lateral thoracic x-ray?

Setting up the tube tilt in a lateral thoracic x-ray typically requires no tube tilt. In a standard lateral projection, the x-ray beam is directed perpendicular to the film or detector to ensure that the thoracic structures are adequately imaged without distortion. A direct, perpendicular beam minimizes the chances of artifacts and ensures the proper delineation of anatomical structures such as the vertebrae, ribs, and lung fields.

Implementing a tube tilt could cause overlapping of anatomical structures or distortion of the image, which would obscure diagnostic details. Therefore, in this context, maintaining a neutral position with no tilt is essential for achieving high-quality radiographs of the thoracic area.
