Atom - ANS-Smallest particle of an element
Photons - ANS-X-ray travel as a bundle of energy
Amplitude - ANS-Height of a wave
Frequency - ANS-The number of X-ray waves pass a given point per unit times Auto
transformer - ANS-Transformer operates on the principle of self- induction 1/1000 of
a second - ANS-How short of an exposure is possible with electronic timer
Automatic Exposure Control - ANS-Control is only choice that relates to consistent of
radio graphic quality
falling load generator - ANS-An X-ray machine that makes maximum use of heat
loading potential
transformer - ANS-What components of the X-ray circuit operate on the principles of
mutual induction
electric cloud - ANS-The result of thermionic emission
The focal cup is located at the - ANS-Cathode
K shell - ANS-Characteristic radiation produces X-ray at the anode as a result of outer
shell electrons filling holes in the ?
10% - ANS-mA station must be within 10% of one another
5% - ANS-When exposure is tested it must be within 5%
2% of SID - ANS-The x-ray beam and collimator light field must coincide to within
, Penetrating Ability - ANS-X-ray beam is accurate the result must be +_ 4 kvp
+_1.2 inches - ANS-The accuracy of collimating at 60 in SID
No lower than 63 kvp and no higher then 77 kvp - ANS-The accuracy of 70 kvp must be
CCD - ANS-Maybe used instead of a vidicon and plumb-icon tubes
Using an increased SID for radiographic imaging of the chest is intended to -
ANS-Minimize heart magnification
75% of central axis beam intensity - ANS-Compared to the central axis of the x-ray
beam the anode side of the useful beam is
Increasing the SID results in decreased beam divergence and - ANS-Increased spatial
resolution
spatial resolution - ANS-Is synonymous with detail
Kvp primarily controls - ANS-Electric potential and bean quality
An image that has high contrast will have - ANS-Few shades of gray
Coherent scattering event may also be called - ANS-Classic scattering
During a serious of portal cheat x-rays, the technologist fails to adjust the kvp for an
especially large patient. This is likely to result in - ANS-quantum mottle
Bremsstrahlung X-ray photons are produced by electrons interactions with which aspect
of the tungsten atom? - ANS-Positive charge of the atomic nucleus
An image is taken using 10mAs with 5:1 grid. What mAs is needed to maintain receptor
exposure when switching to a 16:1 grid - ANS-30mAs
