TABLE 2–2
COMMON EXPOSURES
Note:
The operator selects the following parameters:
D
Focal track (Mo, Rh)
D
Filter (Mo, Rh, A1)
D
Focal spot (0.3 or 0.1)
D
Screen–film combination,
D
kV values,
D
mAs values.
The system displays the inhibit conditions.
Selecting the screen-film combination in Manual Mode has no effect. The user is
recommended to consider the speed of the screen-film combination when
selecting the kV and mAs values.
According to the thickness and density of the breast to be examined, select a configuration
from Table 2–1, with suitable kV values.
Note that while the examination of a very dense breast using the rhodium or molybdenum
tracks provides similar contrast images, the same breast examined via the rhodium track
benefits from better tissue visualization and a lower average glandular dose.
Tables 2–2 (below) gives examples of the most frequently used configurations and kV
values.

If the operator selects an incorrect configuration (filter selection error), the system
will select an authorized configuration by automatically changing the filter. A
message appears on the first line of the readout.
It is recommended to use a Bucky.
The screen/film combination selection depends on user preference.
The mAs value selection depends on the screen speed.
