Chapter A - GENERAL & TECHNICAL DATA
DEFINITION OF MEASUREMENT CRITERIA
Exposure time
The beginning and end points of the exposure time are defined at 70% of the peak radiation
waveform measured with a calibrated X-ray monitor.
Peak tube potential
Is defined as the measured high voltage mean value measured with a calibrated non-invasive
kVp meter.
Tube current
Is defined using the resistance and voltage over the feedback resistor measured with a cali-
brated multimeter. The mA value is then the voltage divided by the resistance.
The nominal X-ray voltage together with the highest X-ray tube
current obtainable from the high-voltage generator when
operated at its nominal X-ray tube voltage
80 kV 12mA
The highest X-ray tube current together with the highest X-ray
tube voltage obtainable from the high-voltage generator when
operated at its highest X-ray tube current
12mA 80kV
The X-ray tube voltage and X-ray tube current which result in the
highest electric output power
80kV 12mA
The nominal electric power for a load time of 0.1s and at the
nominal X-ray tube voltage
80 kV 12mA - 1500W
Nominal anode input power of the X-ray tube
1344 W
Maximum anode heat content of the X-ray tube
35 kJ
