unwanted exposure caused by scatter radiation
Choose an answer
1 Attenuation 2 Primary Radiation
3 Direct Detector technology 4 fog
Don't know?
Terms in this set (165)
,Attenuation reduction in intensity as the beam passes through
matter
Automatic Rescaling process by which images are produced with uniform
brightness and contrast regardless of the amount of
exposure
Brightness function of a display monitor; changes image
lightness/darkness (density)
Density DARKNESS
Direct Detector technology uses amorphous selenium as the active detector
material
Distortion misrepresentation of the true size or shape of an
object
(magnification and true distortion are two types)
Exposure Index (EI) Numeric representation of the total x-ray exposure
to the receptor (S-value)
Exposure Latitude Range of exposures that can be used and still result
in the capture of a diagnostic quality image
Grid device consisting of thin lead strips cleans up
scattor
Indirect Detector technology 2-step process that uses amorphous silicon to
covert x-ray energy to light and then to electrons
Latent Image invisible image created after exposure but before
processing
Penetrating Ability ability of an x-ray beam to pass through an object;
controlled by the kilovolt peak of the beam
, Primary Radiation X-ray beam after it leaves the x-ray tube and before
it reaches the object
Three major classifications of film/screen radiography
diagnostic radiographic imaging fluoroscopic imaging
digital or computerize imaging
Four requirements to produce an x- vacuum
ray source of electrons
method to accelerate electrons
method to stop the electrons
Scatter radiation 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)
photographic factor density- kVp (color)
contrast- mAs
geometric factors recorded detail (magnification)
- SID
-OID
distortion (depth perseption
-Size
-Shape
Source-to-image distance (SID) 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
window level controls image brightness
window width controls contrast
Object-to-image distance (OID) distance between patient and image receptor
