Leakage Technique Factors
80 kV, 600 mAs/h
(80 kV, 10 mA, duty cycle 1:59, for example 7.4 s exposure per 7 minutes 17 seconds cool-down period)
90 kV, 600 mAs/h
(90 kV, 10 mA, duty cycle 1:59, for example 4.9 s exposure per 4 minutes 49 seconds cool-down period)
Measurement Bases
Tube voltage: Actual X-ray radiation is monitored by Non Invasive Evaluator of Radiation Output.
Tube current: The mA is measured by monitoring current in the HT return line, which equals the tube current.
Exposure time: Exposure time is measured the open time of gate circuit which distributes high voltage to X-ray
tube head assembly, by counter (TP8 – TP GND on CPU1 PWB)
Collimator
Panoramic slit and Cephalo slit,
