Measurement criteria for exposure time
Exposure time Consists of beginning and ending
points as measured by a
calibrated x-ray monitor at 70%
of the peak radiation waveform.
kV The high voltage mean value
received after measurement with
a calibrated x-ray monitor.
mAs The resistance value divided by
voltage. A calibrated x-ray
monitor measures the voltage
over feedback resistor and
provides a mAs value.
The nominal x-ray voltage 39kV is obtained at highest tube current 50
mA.
