Piranha & QABrowser Reference Manual
The displays with measured values are continuously updated every four seconds.
Add 10 mm of aluminum. The Piranha will "notice" that the filtration is changed and
shows a new total filtration value.
The dose rate is now much lower. The added filtration does not affect measured kVp at
all.
Note how the Piranha directly responds to a sudden change of the filtration. The display
is continuously updated with the kV, time and dose-rate. The dose rate value decreases
when the extra 10 mm Al is put in the beam but the continuously updated kV value is
practically are the same.
