3.1.3 FOCAL SPOT INDICATORS AND SELECTORS
LARGE FOCAL SPOT: Indicates that the “Large Focal Spot” of the X-ray Tube
has been selected.
SMALL FOCAL SPOT: Indicates that the “Small Focal Spot” of the X-ray Tube
has been selected.
FOCAL SPOT SELECTORS: Each push-button selects the related Focal Spot
of the X-ray Tube, keeping kVp and mAs constant (maximum mA available and
minimum Exposure Time).
The Focal Spot change can be done 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.
The Focal Spot may also be selected:
• according to the selected mA station.
• by pressing “ON”+“mA or mAs increase” push-buttons to select Large
Focal Spot, or by pressing “ ON ”+“mA or mAs decrease” push-buttons
to select Small Focal Spot.
