Goal: Tube conditioning is
necessary to prepare the tube for exposures with high voltage
Precondition:
select the large focus
Collimator has been closed
cover the
collimator with lead cover plate or lead apron
system is in
application mode
connect the scope
to EH:X3 (1V/DIV),scale 20kV/V, trigger external
CTRL_X_C/ at EH:X8 Time Base 2ms/div
Procedure: please execute the conditioning with the following procedure
(values)
Result:
Please import the following text in
the helpscreen.
Explanation: Warning! Radiation is released during
the procedure!
The door of the
exam. room must be closed.
The collimator of
the selected tube must be closed.
The II should be
protected against X-ray with a lead apron.
Connect the
oszilloscope to the measuring points mentioned
This procedure
must be performed for each new installation, tube replacement, but also if a
symptom points to any kind of tube arcing.
The tube to be
conditioned must be selected. Select the tube on the UI.
If possible
release the exposures from a radiation protected area.
During the
adjustment X-rays are released with an increasing kV. The kV value reached without
arcing of the tube must be entered into the result field.
Procedure:
Select the kV/ mAs
start values mentioned on the left side of the screen.
Make an exposure
and wait 20sec. ´till you release the
next exposures
Increase the kV
until you reach the max. kV. If an
arcing is detected, ERROR number or displayed on the scope
decrease the kV one step and try the
procedure once again.
The maximum
reached value without arcing has to be filled in the “corrected kV max. “
field.
This value
determines the max. kV for application and adaption.
