RTE 1401 exam 2 | UPDATED Questions with 100% Verified Answers
Question:
Attenuation
Answer:
reduction in intensity as the beam passes through matter
Question:
Automatic Rescaling
Answer:
process by which images are produced with uniform
brightness and contrast regardless of the amount of exposure
Question:
Brightness
Answer:
function of a display monitor; changes image
lightness/darkness (density)
Question:
Density
Answer:
DARKNESS
Question:
Direct Detector technology
Answer:
uses amorphous selenium as the active detector material
Question:
Distortion
Answer:
,misrepresentation of the true size or shape of an object
(magnification and true distortion are two types)
Question:
Exposure Index (EI)
Answer:
Numeric representation of the total x-ray exposure to the
receptor (S-value)
Question:
Exposure Latitude
Answer:
Range of exposures that can be used and still result in the
capture of a diagnostic quality image
Question:
Grid
Answer:
device consisting of thin lead strips cleans up scattor
Question:
Indirect Detector technology
Answer:
2-step process that uses amorphous silicon to covert x-ray
energy to light and then to electrons
Question:
Latent Image
Answer:
invisible image created after exposure but before processing
Question:
Penetrating Ability
, Answer:
ability of an x-ray beam to pass through an object; controlled
by the kilovolt peak of the beam
Question:
Primary Radiation
Answer:
X-ray beam after it leaves the x-ray tube and before it reaches
the object
Question:
Three major classifications of diagnostic radiographic
imaging
Answer:
film/screen radiography fluoroscopic imaging digital or
computerize imaging
Question:
Four requirements to produce an x-ray
Answer:
vacuum source of electrons method to accelerate electrons
method to stop the electrons
Question:
Scatter radiation
Answer:
non-diagnostic radiation photons that interact with the body's
matter in such a way that the resulting photon continues its
travel in a different direction. (may or may not actually reach
image receptor)
Question:
photographic factor
, Answer:
density- kVp (color) contrast- mAs
Question:
geometric factors
Answer:
recorded detail (magnification)
- SID
-OID distortion (depth perseption
-Size
-Shape
Question:
Source-to-image distance (SID)
Answer:
standardized distance between the point of x-ray emission in
the x-ray tube (Focal spot) and the image receptor - affects the
relative intensity of the radiation as it reaches the image
receptor
Question:
window level
Answer:
controls image brightness
Question:
window width
Answer:
controls contrast
Question:
Object-to-image distance (OID)
Question:
Attenuation
Answer:
reduction in intensity as the beam passes through matter
