The procedure can be cancelled by pressing Cancel or Done.
The seasoning procedure starts with 50kV, 2mA and makes two 10 second exposures. The
kV is then increased by 10kV up to the maximum. Two exposures are done with every kV.
There is a 5 second wait time between every exposure. The maximum kV value depends on
the configuration and the maximum kV set.
The exposure values are automatically changed during the procedure. In the GUI you can
see kV, mA, time and exposure and error counters. You can also see the status of the proce-
dure, which can be: Ready, Exposure, Wait, Error or OK. If there appears a tube head arching
error during the procedure, it returns to the previous used kV. If you get any other error mes-
sage, the exposure is repeated using the same values.
If you receive 10 errors combined, the procedure is stopped and you get an Error status.
If the procedure is finished successfully, you get Status OK.
A successfully performed seasoning procedure total time takes approximately:
2D: 120s
3D: 150s
The exposure button can be held down during the seasoning procedure or can be released in
between the exposures. If you release the exposure switch during an exposure the exposure
is repeated without an error.
4.5 Taking a test exposure
Select Test exposure (i460) on the Special functions display. This option allows you to take a
test exposure. The test exposure is taken with the latest used collimation, i.e. the selected
program, segmentation and jaw size will affect to the collimation.
Select the desired exposure parameters: kV and mA values and exposure time and touch the
Test field. The text Ready appears to the bottom of the display and the test exposure can be
performed.
