Density Flashcards
these are parameters controlled during the imaging process
Technical Factors
these are the patient related factors influence the amount of xray that attenuate oenetrate and absorb
Patient Consideration
technical factors for density
technical factor for contrast
kVp, mAs, SID
kVp
patient consideration for density
patient consideration for contrats
patient thickness
tissue density
contrast media
pathology
patient thickness
contrast media
thse relate to how the radographic film is developed
processing factors
additional variables can indirectly imaoct density
other factors
processing factors
temperature
time
activity
other factors
grid
filter
beam restriction / collimation
fog
additional variables can indirectly impact density
Other Factors
degrades contrast by introducing unwanted fogging to the radiograph
under hadto is???
Scatter Radiation
grid
collimation
directly affects the sharpness and resolution of the image based on the configuration of the xray beam
under hadto niya kay??
Geometric Factors
FSS
SID
OID
is a major cause of image bluering and loss of detail
under hadto kay??
Motion
time of exposure
patient movement
image receptor movement
refers to the enlargement of the image compared to the actual size of the object
Size Distortion (Magnification)
it occurs dur to the divergence of the xray beam
SID
OID
Size Distortion (magnification)
refers to the misrepresentation lf the shape of the object being imaged this can result in elongation or foreshortening of anatomical structure
under niya ano??
Shape Distortion
tube angulation
image receptor angulation
part angulation
