mAs - (ANSWER)______ determines the quantity (number) of x-rays that will be needed to prevent
quantum noise
directly - (ANSWER)mAs and receptor exposure are ___________ proportional
kVp - (ANSWER)______ is the quality (energy) of x-rays that will be needed for penetration and subject
contrast.
15% rule - (ANSWER)This rule states that it only takes a 15% increase in kVp in order to double the

false - (ANSWER)True or false: The size of the beam should be bigger than the area of interest.
anode heel effect - (ANSWER)The heel of the anode will absorb x-rays, therefore the greatest number of
x-rays are toward the cathode end of the x-ray tube, this is known as __________ _____ _________
inverse - (ANSWER)Patients factors (size and thickness) and receptor exposure have an ___________
relationship
spatial resolution - (ANSWER)__________ _______________ is a measure of how well an imaging
system can display 2 closely space objects as separate. Or what determines the sharpness of structural
lines in the digital image.
line pairs per millimeter - (ANSWER)What is spatial resolution measured in?
greatest; smallest - (ANSWER)The ____________ matrix and the ___________ pixel size will give the
best spatial resolution.
smaller - (ANSWER)The _____________ the FOV the better the spatial resolution
21 - (ANSWER)Most radiologists use a _____ inch monitor in portrait mode to view images.
