5. Measurements with the Piranha System
Radiography

5. It is recommended to make a check
measurement at 70 kV to confirm that the
detector area is uniformly radiated.
The Piranha automatically changes back to the previous selected kV range. As
default this is radiography range R2 indicated by a [4] on the QABrowser screen.
6. Set kVp and mAs (or mA/time) to the
desired values.
7. Make an exposure. The RTI logo flashes
to indicate that the Piranha has detected
the exposure.
The Piranha now first analyses the beam and displays the type of waveform. This is
done once for every test.
Then the estimated total filtration is displayed (estimated in the range of 50 - 150 kV).
Depending of the selection of display parameter different display screens may be
presented.
