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 visualize fully the bone and
soft tissue structures.
The complete structure of manubrium, sternum and xiphisternum
should be projected just clear of ribs and in true lateral
position.
