MAM 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%.
Live readings are time since start trig.
kVp is calculated from an average of samples above ~33 % 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.
Live readings of dose rate, kVp and HVL are moving averages. Final readings are based on the whole
measurement.
PARAMETERS IN DOSE RATE WAVEFORM
T: Time
P1, P2, P3: Pulses
DR: Dose rate
: Dose
PARAMETERS IN TUBE VOLTAGE WAVEFORM
T: Time
P1, P2, P3: Pulses
kVp: Peak tube voltage
NOTE! If measurements are made simultaneously with the MAM sensor and mAs cable, any
shared parameter (time, pulses or pulse rate) will be taken from the MAM sensor.
