Visibility of the recorded detail refers to what image quality attribute
Brightness
Accuracy of the structural lines refers to what image quality attribute
Distortion
Spatial resolution
How would an area with increased density on the film image be described when viewed on a display monitor
Decreased brightness
Excessive radiation exposure to the IR would result in a digital image displayed with
Acceptable brightness
Density fluctuations on a radiographic image could be a result of
quantum mottle
Without exposure technique compensation, removing a grid would result in the film image displaying
increased density
decreased contrast
Without exposure technique compensation, increasing the film-screen speed would result in the film image displaying
increased density
decreased recorded detail
without exposure technique compensation, increasing SID would result in the digital image displaying
increased spatial resolution

High Contrast
Short scale
High contrast
Black and white, few gray
High contrast is a result of
low kVp
Low contrast
Long scale
Low contrast
gray image, many shades of gray
low contrast is a result of
high kVp
Beam description/quantity
# of photons in the useful beam
output, intensity, and exposure
Unit of exposure
roentgen, coulomb/kg
Bream description/quality
penetrating ability of beam
highly penetrating beam
hard beam
low penetrating beam
soft beam
MEasure of tube current
milliamperage
length of time electrons travel from cathode to anode
exposure time
mAs is _____________ proportional to exposure
directly
Density/IR exposure should remain unchanged as long as mAs remains unchanged
Reciprocity Law
double time
double intensity
Increases speed if electrons across tube
controls penetrability of beam
influences quality of beam
kVp
how do you use the 15% rule to maintain exposure
increase kVp by 15%
cut mAs in half
Adjustments in exposure are generally made with
mAs because kVp affects image contrast nd is not always desirable to do so
Distance changes what in xrays
# of photons remain the same, but distribution of photons vary with distance
