Exam 5: The X-Ray Tube

With a rotating anode,the focal spot becomes a focal:

The _______________ is used to calculate the length of time needed between exposures so that the tube's heat loading capacity is not exceeded.

The best situation is to have a _______________ actual focal spot and a ______________ effective focal spot.

The protective tube housing is lined with:

Heat from x-ray production is removed through conduction by the heat traveling from:

The relationship between the actual focal spot size,effective focal spot size,and anode target angle is called:

The filament is primarily made of:

The focusing cup is part of the:

X-ray tubes with a stationary anode design may be found today:

The rotor is supplied with electric current through the x-ray circuit.

Prepping the rotor but not making an exposure on a regular basis is unrelated to tube damage or failure.

The cathode:

The cathode includes the:

The rotating anode design uses a disc whose core is made of:

To take advantage of the anode heel effect,the thicker part of the anatomy being imaged should be placed under the anode end of the tube.

Most x-ray tube target angles range between:

Which of the following occurs last during x-ray production?

The atomic number of tungsten is:

Copper can be found __________________ of the rotating anode.

One of the reasons that molybdenum is used in rotating anodes is because it is:
