1. What is the primary purpose of filtration in the x-ray
beam?
• A. Increase patient dose
• B. Increase image contrast
• C. Reduce scatter radiation
• D. Remove low-energy photons
Correct Answer: D
Filtration removes low-energy x-ray photons that would be
absorbed by the patient without contributing to image
formation, thereby reducing patient dose.
2. The ALARA principle is intended to minimize:
• A. Image contrast
• B. Radiation exposure
• C. Patient motion
• D. Equipment wear
,Correct Answer: B
ALARA stands for “As Low As Reasonably Achievable” and is
a radiation protection principle designed to minimize
radiation exposure to patients and personnel.
3. Which factor primarily controls the quantity of x-rays
produced?
• A. kVp
• B. mAs
• C. Filtration
• D. SID
Correct Answer: B
mAs directly controls the number of electrons crossing the x-
ray tube and therefore the quantity of x-ray photons
produced.
4. Increasing kVp will primarily affect:
• A. Density only
• B. Contrast only
• C. Both density and contrast
• D. Spatial resolution
,Correct Answer: C
Increasing kVp increases beam penetration, affecting both
image density and contrast.
5. The purpose of a grid is to:
• A. Increase image density
• B. Reduce patient dose
• C. Absorb scatter radiation
• D. Improve spatial resolution
Correct Answer: C
Grids absorb scatter radiation before it reaches the image
receptor, improving image contrast.
6. Which interaction is most responsible for image contrast
in diagnostic radiography?
• A. Coherent scattering
• B. Compton scattering
• C. Photoelectric effect
• D. Pair production
Correct Answer: C
The photoelectric effect contributes most to image contrast
by completely absorbing x-ray photons in tissues of varying
atomic numbers.
, 7. What is the function of the anode heel effect?
• A. Increases exposure time
• B. Reduces heat production
• C. Causes variation in beam intensity
• D. Improves image sharpness
Correct Answer: C
The anode heel effect causes x-ray beam intensity to be
greater on the cathode side than the anode side.
8. The inverse square law relates radiation intensity to:
• A. Time
• B. Distance
• C. Filtration
• D. Beam energy
Correct Answer: B
Radiation intensity decreases proportionally to the square
of the distance from the source.
9. Which unit measures absorbed dose?
• A. Roentgen
• B. Sievert
