ABSTRACT
Positioning for lateral lumbo-sacral junction projection. https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9781315382210/8ca82e7c-bd07-4171-b4f5-ebaded57b5b3/content/fig2_54a.jpg" xmlns:xlink="https://www.w3.org/1999/xlink"/>
The patient lies on either side on the Bucky table with the arms raised and the hands resting on the pillow. The knees and hips are flexed slightly for stability.
The dorsal aspect of the trunk should be at right angles to the image receptor. This can be assessed by palpating the iliac crests or the posterior superior iliac spines.
The coronal plane running through the centre of the spine should coincide with, and be perpendicular to, the midline of the Bucky.
The image receptor is centred at the level of the fifth lumbar spinous process.
Non-opaque pads may be placed under the waist and knees, as necessary, to bring the vertebral column parallel to the image receptor.
