phosphor
plate
Nearly all new x-ray machines manufactured today use____________generators. Correct
Answ_high frequency
The target of the x-ray tube is made of: Correct Answ_Tungsten
What is the standard control limit for the field light to radiation field alignment test Correct
Answ_+- 2% SID
,What is the standard control limit for the beam (central ray) alignment test? Correct
Answ_within 1 degree of perpendicular
How often should lead aprons and gloves be checked for cracks or holes Correct
Answ_every 6 months
How can detector fog be prevented when using computed radiography cassettes Correct
Answ_protect the cassette before and after exposure
Which of the following will result in increased radiographic density Correct
Answ_Increased: mA, exposure time, and kVp
If the radiographic image is overexposed, which of the following changes in exposure factors
should be used to correct the problem Correct Answ_Decrease the mAs
The relationship between SID and beam intensity is expressed in the: Correct Answ_Inverse
square law

properties)? Correct Answ_Density
Contrast
Distortion
Recorded detail
Contrast is primarily controlled by altering the: Correct Answ_kVp
Scatter radiation fog affects radiographic quality by causing Correct Answ_decreasing
contrast
A change from small focal spot to the large focal spot will result in: Correct Answ_decreased
image sharpness/detail
An increase in object image receptor distance (OID) will result in: Correct Answ_Increased
magnification
Motion of the patient, the tube, or the IR during the exposure will result in decreased: Correct
Answ_recorded detail
, What does quantum mottle (noise) look like on a radiographic image? Correct Answ_finely
speckled or grainy areas
Quantum mottle with a digital imaging system is caused by: Correct Answ_the mAs being
set too low
Which of the following will increase recorded detail? Correct Answ_*increase in SID
*Decrease in focal spot size
