Chapter 02: The X-ray Beam
Fauber: Radiographic Imaging and Exposure, 6th Edition
MULTIPLE CHOICE
1. The _____ is the portion of the x-ray tube that contains the filament.
a. cathode
b. anode
c. rotor
d. rotating disk
ANS: A
The filament, the source of electrons during x-ray production, is located in the cathode.
2. The cathode filament is made of:
a. tungsten.
b. rhenium.
c. molybdenum.
d. lead.
e. nickel.
ANS: A
The cathode filament is made of tungsten.
3. The focusing cup:
a. surrounds the anode.
b. has a positive charge.
c. has a negative charge.
d. focuses the x-ray beam.
ANS: C
The focusing cup, surrounding the filament on three sides, has a negative charge, keeping the
negatively charged electrons focused.
4. In a dual-focus tube, how many filaments are energized at any one-time during x-ray
production?
a. One
b. Two
c. Four
d. An infinite number
ANS: A
Only one filament is energized at any one-time during x-ray production.
5. The focusing cup is made of:
a. tungsten.
b. rhenium.
c. molybdenum.
d. lead.
e. nickel.

6. _____ is the phenomenon that occurs around the filament during thermionic emission and
prevents the further escape of electrons from the filament.
a. Saturation current
b. Space charge effect
c. mA rectification
d. Line focus principle
ANS: B
The space charge effect limits the number of electrons in the space charge by preventing
additional electrons from being boiled off the filament.
7. The positive side of the x-ray tube is the:
a. anode.
b. cathode.
c. window.
d. stream of electrons.
ANS: A
The anode is the positive side of the x-ray tube, and the cathode is the negative.
8. The maximum speed the rotating anode will typically achieve is _____ rpm.
a. 3200
b. 5000
c. 10,000
d. 20,000
ANS: C
Rotating anodes rotate at a set speed ranging from 3000 to 10,000 revolutions per minute
(rpm).
9. What is the base material of the anode disk?
a. Tungsten and molybdenum
b. Tungsten and graphite
c. Molybdenum and graphite
d. All options are correct.
ANS: C
The base of the rotating anode disk is made of molybdenum with a graphite layer.
10. What is the name of the fixed physical area on the anode target that is struck by the electron
stream?
a. Focal spot
b. Focal point
c. Focal range
d. Focal radius
ANS: A
The focal spot is the fixed physical area on the focal track of the anode target where electrons
strike.

b. Rotor
c. Focusing cup
d. Rheostat
ANS: A
Located outside the envelope of the x-ray tube, the stator is an electric motor that turns the
rotor.
