Shortest possible exposure time - ANSWER the minimum response time of an automatic
exposure control (AEC) (also called photo timing)
Inherent filtration (built in) - ANSWER together, the filtering effect of the x-ray tube's
glass envelope and its oil coolant are referred to as:
Periodic checks for cracks - ANSWER proper care of leaded aprons includes:
Thermionic emission - ANSWER the source of electrons with the x-ray tube is a result of:
Underexposed radiographic image - ANSWER inadequate collimation when using the AEC
often results in:
Extends x-ray tube life - ANSWER low mas/high kvp exposure factors, avoiding lengthy
anode rotation, avoiding exposures to a cold anode
Tube current, target material - ANSWER the total number of x-ray photons produced at
the target is contingent upon:
Filament circuit - ANSWER in which of the following portions of the x-ray circuit is a step
down transformer located?
Grid - ANSWER what's the device that is used to absorb scattered radiation produced in
the patient before it reaches the IR?

, Acts as an additional filter, reduce tube output, resulting in arcing and tube puncture -
ANSWER as the x-ray tube filament ages, it becomes progressively thinner due to
evaporation. The vaporized tungsten is frequently deposited on the window of the glass
envelope. This may:
Overexposure, over development - ANSWER a film emerging from the automatic
processor exhibits excessive density. This may be attributed to:
Ejects an inner shell tungsten electron - ANSWER in the production of characteristic
radiation at the tungsten target, the incoming electron:
Target angle effects - ANSWER severity of the heel effect, focal spot size, heat load
capacity
Characteristics of the x-ray tube - ANSWER target material has a high atomic number and
melting point, useful beam at port window, cathode assembly receives both low and high
voltages.
Thermionic emission - ANSWER NOT associated with the anode.
Rectifiers - ANSWER in order to be used more efficiently by the x-ray tube, alternating
current is changed to direct current by the:
Leakage radiation - ANSWER radiation that passes through the tube housing in directions
other than that of the useful beam is termed?
Tungsten alloy - ANSWER has high atomic number and melting point, can readily
dissipate heat. (usual choice for target material in equipment)
Causes pitting or many small surface melts on the anode - ANSWER vaporized tungsten
on the glass envelope, loss of anode rotation, large amounts of heat to a cold anode
