174 Multiple choice questions
Term 1 of 174
anode
a method by which digital radiography manufacturers provide feedback to the technologist
regarding the estimated exposure on the detector
Density is greater towards the cathode side of the tube, and less towards the anode side.
(thicker body part towards cathode)
a positively charged electrode by which electrons leave an electrical device. It conducts
electricity and radiates heat and contains the target.
a very tightly wound wire, when heated up it allows electrons to become free
Term 2 of 174
non-ionizing radiation
Radiation that has enough energy to move atoms in a molecule around or cause them to
vibrate, but not enough to remove electrons, . . . Examples of this kind of radiation are
sound waves, visible light, and microwaves
has enough energy to remove tightly bound electrons from atoms, thus creating ions
x-rays, gamma rays, cosmic rays
another method of limiting the beam size
these are either attached to the housing port or the collimator box
An attenuation (absorption) process for x- and gamma radiation in which a photon interacts
with an orbital electron or an atom to form a displaced electron and a scattered photon (x-
ray) of reduced energy.
causes x-rays to be scattered in all directions
,Definition 3 of 174
area of the anode struck by the electrons from the cathode
stationary anode
cathode
filament
anode target
Definition 4 of 174
Damage from x-rays to these cells is passed on to succeeding generations. These effects are
referred to as genetic mutations
radiation induced leukemia
filtration
genetic effects of radiation
medical malpractice
Definition 5 of 174
a US law designed to provide privacy standards to protect patients' medical records and other
health information
Health Insurance Portability and Accountability Act
Federal Food, Drug, and Cosmetic Act

,Term 6 of 174
key factors affecting x-ray quality
inherent Plus added filtration
visible differences between adjacent structures
filament And focusing cup

Half value layer
Definition 7 of 174
when insufficient light is emitted form the phosphors, it produces an image that grainy
increased contrast
grid or bucky
quantum mottle or noise
control booth
Definition 8 of 174
It is a flat sheet of lead that has a hole cut in the center and attached to the x-ray tube port. The
opening can be made in any size or shape; most are rectangular, square, or round and is the
simplest of all beam-restricting devices
tube window
compensating filter
aperture diaphragm
cones and cylinders
, Definition 9 of 174
occurs when incident electrons pass near the positively charged nucleus which results in the
incident electron braking or slowing down, each deflection causes a photon of radiation
makes up most of the primary beam
collimator definition

control booth
Definition 10 of 174
result of low doses delivered over a long period of time
cataracts
radiation-induced malignancies
thyroid
late stochastic somatic effects
alara
late effects of radiation
three types of motion
Term 11 of 174
erythrema dose
the dose that would cause your skin to turn red
photons that interact with the body's matter and travel in a different direction
the absorption of x-ray beam by matter
is the time the electronic timer is set in case the aec fails to terminate exposure
