Basic Patient Position
The patient lies prone on the table with the left side
raised (RAO) approximately 15 degrees, arm and knee of the
raised side to aid stability.

Radiation protection
Direct lead rubber waist level protection, avoid irradiation of
thyroid.
|
Central Ray
The vertical central ray is centred so the emerging beam exits
at a point on the sternum midway between the xiphisternum and
the sternal notch, on the dorsal skin surface this is
approximately 5 cm lateral to the spinous processes on the
raised side at the level of the palpable 8th thoracic verebral
spinous process.

Evaluation of the Image
ID and anatomical markers must be present and correct in the
appropriate area of the film.
Optimal exposure should penetrate all the bone structures and
contrast should be low enough to visualise fully the bone and
soft tissue structures.
The complete structure of manubrium, sternum and xiphisternum
should be projected just clear of the spine.
