Focal Spot Indicator
A focal spot indicator shows the selected focal spot of the X-ray tube: “Small”
or “Large”.
Figure 11: Focal spot indicator
You can change the focal spot by touching this indicator. It keeps kVp and
constant mAs, whenever it is possible. The mA value available is set according
to maximum power, instantaneous power, space charge, etc.
When a focal spot is selected, it sets the highest mA value available for the
selected focal spot and the respective exposure time in order to keep constant
mAs, whenever the mA value does not exceed the maximum tube power and
the exposure time value does not exceed the maximum integration time of the
DR detector (Max ms).
Note
:
You can do the focal spot change whenever the present
conditions of the X-ray tube allow it. The mA station set for the
focal spot change is configured by the field engineer during the
installation.
