Radiographic Imaging - EXAM 1 UPDATED
ACTUAL Exam Questions and CORRECT
Answers
What are the components of an anode assembly? - CORRECT ANSWER - Anode, Stator,
and Rotor
What are the components of a cathode assembly? - CORRECT ANSWER - Filaments,
Focusing Cup, and Associated Wiring
What is the "actual focal spot"? - CORRECT ANSWER - physical area of the focal track.
LARGER
Which side of the X-ray tube is positive? - CORRECT ANSWER - anode
What is the "effective focal spot"? - CORRECT ANSWER - focal spot that is projected out
of the tube toward the object being radiographed. SMALLER
Which side of the x-ray tube is negative? - CORRECT ANSWER - cathode
What is the velocity of electromagnetic energy is equal to? - CORRECT ANSWER -C=3
x 10 to the 8th power m/sec
C=nxl
What is the line focus principle? - CORRECT ANSWER - Increase angle of target means
larger focal spot and a smaller effective beam.
What is a possible result from the line focus principle? - CORRECT ANSWER - Anode
Heel Effect
, Why is the rotating anode preferred over the stationary anode? - CORRECT ANSWER -
Greater surface area and better heat dissipation
What is meant by the term "off-focus" radiation? - CORRECT ANSWER - Radiation
created anywhere but the tungsten x ray target
What is ionization energy? - CORRECT ANSWER - the energy required to remove an
electron from an atom
What is the difference between mechanical energy and potential kinetic energy? - CORRECT
ANSWER - Potential: stored mechanical energy
Kinetic: active heat energy
What is an ion? - CORRECT ANSWER - an atom or molecule with a net electric charge
due to the loss or gain of one or more electrons.
What is the difference between atomic number and atomic mass? - CORRECT ANSWER -
Atomic Number: number of protons in an atom
Atomic Mass: number of protons and neutrons
What is an isotope? - CORRECT ANSWER - Atoms of the same element that have
different numbers of neutrons
How are elements arranged on the periodic table of elements? - CORRECT ANSWER -
Groups, periods, and families
What is the difference between a valence shell and a valence electron? - CORRECT
ANSWER - Valence Shell: Outermost shell of any atom
Valence Electron: the electrons that reside in the valence shell
