SWIMMER’S VIEW
• the patient is placed prone on the table with the left arm abducted 180° and the right arm by the side, as if swimming the crawl. The central beam is directed horizontally toward the left axilla. The radiographic cassette is against the right side of the neck, as for the standard cross-table lateral view
To demonstrate : Fractures of C-7, T-1, and T-2

THORACIC RADIOLOGY (1)
• For the anteroposterior view of the thoracic spine, the patient is supine on the table, with the knees flexed to correct the normal thoracic kyphosis. The central beam is directed vertically about 3 cm above the xiphoid process.
![Page 18: SPINE (Edited 19Nov2011)](https://reader035.vdocument.in/reader035/viewer/2022062315/55cf918c550346f57b8e5762/html5/thumbnails/18.jpg)
THORACIC SPINE(AP VIEW)
1 = pedicle
2 = Paravertebral line
3 = Border of descending aorta
4 = Intervertebral disk
5 = Superior endplate
6 = Inferior endplate

THORACIC RADIOLOGY (2)
• For the lateral view of the thoracic spine, the patient is erect with the arms elevated. To eliminate structures that would obscure the bony elements of the thoracic spine, the patient is instructed to breathe shallowly during the exposure. The central beam is directed horizontally to the level of the T-6 vertebra with about 10° cephalad angulation. The film in this projection demonstrates a lateral image of the vertebral bodies and intervertebral disk spaces.
