HEAD-ASSEMBLY ROTATION

OM-0481R1
This indicator displays the selected Focal Spot of the X-ray Tube: "Small" or
"Large". The Focal Spot is changed by pressing on this indicator. It keeps kVp
and constant mAs, whenever it is possible.
Small and Large Focal Spots can overlap each other, refer to the graphic below
to view an example of Focal Spot change.
mA stations in Small Focus
The maximum mA station for the Small Focal Spot and the
minimum mA station for the Large Focal Spot can be configured
by the field engineer during the installation.
Tube Capability can be limited to 80% by pressing on the "Power Reduction"
button and selecting the desired power percentage (100% or 80%). In this case,
if the 80% limitation is selected, the range of radiographic parameters may be
conditioned and the values selection could be automatically adjusted.
It displays the rotation and angulation of the X-ray Tube.
The value displayed beside the upper symbol, indicates the

Head-Assembly rotation on its transversal axis (roll rotation).
The value displayed beside the lower symbol, indicates the

Head-Assembly rotation on its horizontal axis (pitch rotation).
