COLLIMATOR CONTROLS
Collimator controls consist of a push-button to switch on the Collimator lamp
and two knobs to open or close the internal blades of the Collimator.
(Also, refer
to Collimator manuals.)
After pressing the Collimator Lamp push-button, the Lamp remains on for
several seconds to allow for patient/film alignment before turning off
automatically.
PROLONGED LIGHTING WITHOUT ALLOWING THE LAMP
TO COOL CAUSES THE COLLIMATOR TO OVERHEAT IN
THE INTERNAL AREA NEAR THE LAMP.
Exposure field on the Bucky is adjusted by setting the two knobs. The table on
the Front Panel shows the number to set with the knobs to open the blades
according to the SID and cassette size to be used.
