MEASUREMENT CRITERIA FOR LOADING FACTOR
CONDITIONS
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.
kVp
The high voltage peak value measured over the high
voltage feedback resistor with a calibrated voltage device.
mA
The tube current mean value calculated by dividing the
voltage over the feedback resistor value. The voltage is
measured with a calibrated voltage device.
The nominal x-ray voltage 70kV is obtained at highest
tube current 7mA.
The nominal tube current 7mA is obtained at the
highest tube voltage 70kV.
The max. electric output is obtained at 70 kV tube
voltage and 7 mA tube current.
The nominal power/exposure: 490 W
The manufacturer reserves the right to make technical
