Rad 147 Exposure Factors Review

What happens to the absorption when the kilovoltage peak (kVp) is increased?

• Absorption increases

• Absorption decreases

• Absorption remains the same

• Absorption fluctuates unpredictably

As the kilovoltage peak (kVp) is increased, what is the effect on the contrast of the image?

• Contrast increases

• Contrast decreases

• Contrast remains the same

• Contrast becomes inverted

What is the relationship between kilovoltage peak (kVp) and Linear Energy Transfer (LET)?

• Directly proportional

• Inversely proportional

• No relationship

• The relationship varies

What is the effect on Relative Biological Effectiveness (RBE) when the kilovoltage peak (kVp) is increased?

• RBE increases

• RBE decreases

• RBE remains constant

• RBE is not related to kVp

What is the effect of beam restriction on the receptor exposure and contrast in radiography?

• Beam restriction increases receptor exposure and increases contrast

• Beam restriction decreases receptor exposure and increases contrast

• Beam restriction increases receptor exposure and decreases contrast

• Beam restriction decreases receptor exposure and decreases contrast

What is the relationship between scatter and contrast in radiography?

• Increased scatter increases contrast

• Increased scatter decreases contrast

• Scatter has no effect on contrast

• The relationship between scatter and contrast is not shown

What happens to the spatial resolution when the SID (Source to Image Distance) is decreased?

• Spatial resolution increases

• Spatial resolution decreases

• Spatial resolution remains unchanged

• Spatial resolution is not related to SID

What is the effect on size distortion when the SID is increased?

• Size distortion increases

• Size distortion decreases

• Size distortion remains unchanged

• Size distortion is not related to SID

What happens to the receptor exposure when the SID is increased?

• Receptor exposure increases

• Receptor exposure decreases

• Receptor exposure remains unchanged

• Receptor exposure is not related to SID

What is the effect of increasing x-ray beam intensity have on beam quality?

• Increasing intensity improves quality

• Increasing intensity has no effect on quality

• Increasing intensity reduces quality

• The diagram does not show any relationship between intensity and quality
