R/F SENSOR: MEASUREMENT PARAMETER
DEFINITIONS
Dose and HVL are calculated from all recorded data.
Dose rate
is the average dose rate, calculated as dose/time.
Time starts the first time the dose rate waveform reaches 50% of peak, and ends the last time it drops
below 50%. Intermediate values are time since start trig.
kVp
and total filtration are calculated from an average of samples above ~90 % of peak signal level.
Pulses
are counted at every start trig with more than 4 ms since last end trig.
Pulse rate and dose per pulse are averages from the last 6 pulses.
For measurements longer than 3 s, the final readings of dose rate, kVp, HVL and total
filtration
are moving averages ending approximately 1–2 s before end trig. Intermediate readings are
moving averages.
Note! If measurements are made simultaneously with the R/F sensor and mAs cable, any shared
parameter (time, pulses or pulse rate) will be taken from the R/F sensor.
