mammography. Default values are "DC/HF" and 3.0 mm Al.
8. Make an exposure. Every time the Piranha
recognizes an exposure the RTI logo is
superimposed on screen for a short while.
The Piranha analyses the waveform and shows the
result automatically after the first exposure. If the
result is incorrect the actual waveform type needs to
be set manually, see topic
Settings
for more
information.
The Piranha measures the total filtration for each
exposure (for all measurement types except
mammography). It is shown automatically after the
first exposure.
If you want the QABrowser to lock this value and not
estimate it again for the following exposures, tap
Keep
. You can also enter the total filtration manually
under the settings, see topic
Settings
for more
information.
Up to six values can be shown simultaneously.
Measured kVp, dose, and dose rate values are
compensated depending on actual total filtration
(between 1.5 - 38 mm Al) and waveform type.
The display looks different depending on the type of parameter you selected in step
#3 and if you are using a mAs probe or not. In the pictures below you can see how
the screen looks if you do not measure mAs and if you select just
Tube voltage
.
