Focal Spot Indicator
A focal spot indicator shows the selected focal spot of the X-ray tube: "Small"
or "Large".
Table 17: Focal Spot Indicator
You can change the focal spot by touching this indicator. It keeps kV 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 or the maximum exposure time of the generator.
