(1) Figure 4-5 demonstrates the axillary position. With the patient supine on
the table, the film is positioned so that the axillary area, the tail of the breast, and the
upper quadrant of the breast are included on the film.

(2) The patient is rotated toward the side being examined until the tail of the
breast is projected beyond superimposition of the chest wall (body rotation is usually
between 15 and 30 degrees).
The CR is directed perpendicularly to the film.
4-10. GENERAL CONDITIONS
(1) Always place the identification markers along the axillary margins of the
film. This will help the radiologist maintain orientation as he interprets the film.
(2) Ensure that coning is such that the breast is demonstrated in a
constricted cone field. The light from the filament will indicate the cone field.
(3) Ensure that the patient's position is as comfortable as possible so she
can more readily maintain the position throughout the exposure.
(4) Wait until you are ready to make the exposure before giving the patient
breath control instructions. The longer she must hold her breath, the greater the chance
for involuntary motion.
