As image contrast depends on kV values used, note that while an increase in the kV value
may reduce the radiation dose to the patient, it will reduce the contrast of the image.
A reduction in the kV value improves film contrast but increases the radiation dose to the
patient.
The choice of priority to dose reduction or to optimum contrast is left to the discretion of the
operator.
Use of the AOP Mode provides the best quality/dose compromise for each priority selected
by the operator.

MATERIAL/FILTRATION COMBINATIONS ARE AVAILABLE TO BE
CHOSEN FROM. IN REGULAR AUTOMATIC EXPOSURE CONTROL
(AEC) MODE, THE SAME CONDITIONS ARE AVAILABLE, AND MAY
BE CHOSEN BY THE USER. HOWEVER, FOR BEST RESULTS, ONLY
CERTAIN CONFIGURATIONS SHOULD BE USED.

CONFIGURATION AS THE STANDARD FOR ALL EXPOSURES LESS
THAN 35 KVP.
FOR THICK (>6 CM) OR DENSE BREASTS, THE MO/RH AND RH/RH
CONFIGURATIONS MAY PROVIDE SAME OF BETTER CONTRAST
WITH REDUCED PATIENT DOSAGE. FINALLY, THE MO/AL AND
RH/AL CONFIGURATIONS SHOULD NOT BE USED UNTIL SPECIFIC
CONDITIONS HAVE BEEN IDENTIFIED WHERE THIS USE OFFERS
ADVANTAGES TO THE PATIENT OVER OTHER OPERATING
