3. Fluorscopy & Radiography operations
3.1 Start-up
System power is applied by pressing the power "On" button on the Control Console. The generator
will go through a start-up routine conducting an automatic self-test that will show on the RAD kVP
Display information usable only to service personnel.
After the power-up has been completed the console shall display normal radiographic factors. If
there is a malfunction, error messages will be displayed on the RAD kVp Display specifying the
fault.
Some indicators on the Console are used to provide service information
during the start-up process. These indicators shall be ignored by the operator until
the unit has completed its power-up sequence.
3.2 Warm-up of x-ray tube
Before effecting X-
ray exposures ensure that the tube is
properly warmed-
up. Make sure that no persons will be
inadvertently exposed to unnecessary X-rays during this
procedure.
Routine exposures shall not be effected unless the tube is previously warmed-up, this
prolongs X-ray tube life.
It is recommended that the following procedure will be performed for X-ray tube warm-up, at
the start of each day and when the tube selected has not been in use for approximately one
hour.
Excessive filament evaporation shortens X-ray tube life.
Minimize evaporation by keeping Exposure "Preparation" time to an absolute minimum.
