EXPOSURE MODE

3–1 AOP Mode
Note:
Note:
CAUTION
The AOP (Automatic Optimization Parameters) Mode controls radiation and allows the
system to select the main parameters.
It optimizes the track/filter/kV configuration as a function of the required image quality,
and of the thickness and density of the breast being examined.
The AOP Mode includes the AEC Mode, and ensures constant density.
The AOP Mode has three options:
D
Contrast (CNT)
D
Dose (DOSE)
D
Standard (STD): a compromise between contrast and dose.
For each of the above options and as a function of the thickness and density crossed, the
AOP Mode selects the track/filter/kV configuration which supplies the lowest dose.
The operator selects;
D
Priority (CNT, DOSE, STD).
D
Focal spot,
The small focal spot is automatically selected in magnification.
D
Screen-film combination.
D
Density correction, when necessary.
Density correction is used only when density change in the image is required.
BREAST COMPRESSION IS ESSENTIAL WHEN USING THE AOP MODE.
The system displays inhibited messages and automatically selects the following
parameters:
D
Track (Mo, Rh),
D
Filter (Mo, Rh, Al).
D
kV values.
D
mAs values.
The system displays the inhibit messages.
The AOP Mode can be used for standard exposures, magnified exposures, or for the
examination of the chest wall.
