Exposure
Exposure release
You can release an exposure either with the release button on the generator ON/
OFF console
2
, on the system control console
3
or with the exposure release foot
switch in controlroom.
You can release an exposure if
❏ no error message appears, and
❏
none of the displays (kV, mAs, ms) flashes
The radiation indicator lights up and a signal sounds during the exposure release.
❏
Observe the following to increase the life of the tube assembly:
– If possible always select 80% tube load at the generator.
– It is essential that you program 80% tube load in the programs with small
focal spot and a tube voltage less than 70 kV.
– Work with the large focal spot below 70 kV tube voltage, if possible.
– Keep the prep time short and possibly “push through” to keep this time
short.
– Let go of the exposure release button immediately after the exposure.

Check the selected exposure data on the integrated generator control console
before every radiation release.
The above instructions should be observed especially at workstations with high
patient throughput (accident stations) to counteract premature wear of the X-ray
tube assembly.
