●● T/F: Fluoroscopic x-ray tubes are designed to operate for longer
periods of time at much lower mA, as compared to a typical diagnostic
tube.
Answer: True
●● T/F: The anode of the image intensification system is positioned
outside the glass envelope, immediately in front of the output screen.
Answer: False
●● T/F: Flux gain is a measurement of the increase in light photons
caused by conversion efficiency of the output screen
Answer: True
●● T/F: Brightness gain deteriorates with use.
Answer: True
●● T/F: Most automatic brightness control systems monitor the current
between the cathode and the anode of the image intensifier to maintain
fluoroscopic image density and contrast.
,Answer: True
