4.1 X-RAY TUBE WARM-UP PROCEDURE
Before effecting X-ray exposures, ensure that the Tube is
properly warmed-up. Make sure that no one will be
inadvertently exposed to unnecessary X-rays during t his
procedure.
Routine exposures should not be effected unless the Tube is previously
warmed-up, this preserves an optimal X-ray Tube life.
It is recommended that the following procedure 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.
This warm-up procedure is used for a typical X-ray Tube.
Consult the X-ray Tube manufacturer instructions for the
actual Tube in use, comparing its recommendations with this
procedure. If there is a conflict with this procedure, comply
with the Tube manufacturer’s instructions.
Perform X-ray Tube warm-up as follows:
Close the Collimator Blades fully.
Select 70 kV, 100 mAs, 200 mA and 500 ms exposure.
Insure that no one will be exposed.
Make a total of three exposures, 15 seconds apart.
Excessive filament evaporation shortens X-ray Tube life.
Minimize evaporation by keeping Exposure “Preparation”
time to an absolute minimum.
