8. Tap
Wave
to view that mA waveform.
The figure to the left shows the mA
waveform. You can use the cursor to analyse
the waveform and read the mA value as well
as estimate the exposure time.
The MAS-1 probe can also be used for measurement of tube current during
fluoroscopy.
To measure fluoroscopy tube current with the Piranha MAS-1 Probe
1. Setup the Piranha according to the description earlier in this manual.
2. Connect the MAS-1 probe to the X-ray generator as described in the MAS-1 User's
Manual.
3. Connect the MAS-1 probe to the external probe input.
4. In the QABrowser select type of measurement.
5. Select
Tube Current
from the menu.
6. The real-time display for tube current is now displayed. Set the generator. Do a
Reset
.
7. Start the fluoroscopy.
8. The figure to the left shows the real-time
display during fluoroscopy. The tube
current is measured and the display is
updated approximately every four
seconds. Note that for low mA values the
mAs and the exposure time may not be
measured. Tap
Hold
to "freeze" current
value in the display. The waveform is also
acquired when Hold is activated.
