Parameters
Tube voltage (kVp)
The average of all samples with compensation for the ripple
(default method)
Time
Irradiation time (Exposure time)
Air kerma (Dose)
Measured air kerma (may be called dose or air kerma in this
manual)
Air kerma rate (Dose rate)
Average air kerma rate (may be called dose rate or air kerma rate
in this manual)
Total Filtration
Estimation of total filtration (for conventional radiography,
fluoroscopy, dental, and CT)
Quick-HVL
Estimation of Half Value Layer (for conventional radiography,
fluoroscopy, dental, and CT)
Half Value Layer
Standard HVL using filters for evaluation on radiography,
fluoroscopy, dental, and mammography (all for both pulsed and
conventional)
kV waveform
Waveform is calculated based on detector signals measured after
different thickness of filtration.
Dose rate waveform
Signal measured from radiation detector (ionization chamber or
solid-state detector).
