Barracuda & QABrowser Reference Manual
1. Set up the Barracuda and the handheld computer according to the description in
Setting Up the Barracuda . Selecting one parameter mode enables you to see
the measured values from a distance of several meters.
2. Mount the MPD using the Pan dental
holder and fixate the cable as
described earlier in this section.
Connect the MPD to the MPM
module using the cable and power
on the Barracuda.
3. The real-time display for Tube
voltage is now displayed.
4. It is strongly advised to make
Position Check to confirm that the
detector area is uniformed irradiated
if you want reliable kVp readings.
Select the Check[C] filter and leave
the room to make the first panoramic
scan.
5. Start the exposure. You do not need to use the whole scan exposure to make a
check measurement since the display is continuously updated during the scan.
When the value is stable within 1.00 ±0.05 release the exposure button.
If the QABrowser tells you Reposition Detector,
please move the detector to the centre of the
beam and try again.
You may need to use a film or other beam alignment tools if the narrow beam is
several mm outside the expected centreline. The dental film image below shows that in
the bottom part of the image you can see a part of X-ray slit image.
