, Radiographic Imaging Exam 2026/2027 – 80 Q&A
Question 1
What is required to produce a radiographic image?
A. A high-energy x-ray beam and a film cassette only
B. X-ray photons passing through tissue and interacting with an image receptor, influenced
by beam quantity, quality, and tissue composition
C. Low-energy photons interacting primarily with air and bone
D. A photostimulable phosphor plate without any x-ray exposure
Answer: B
Explanation: Radiographic image formation depends on x-ray photons traversing anatomic
tissues and reaching an image receptor. The process is directly shaped by the number
(quantity) and penetrating ability (quality) of the primary x-ray beam, along with the specific
density and atomic composition of the tissues encountered.
Question 2
What creates a radiographic image through differential absorption?
A. Uniform attenuation of all x-ray photons by soft tissue
B. Equal transmission of photons through bone and muscle
C. The varying degrees to which anatomic parts absorb the primary beam, structurally
representing the anatomic area
D. Exclusive absorption by the image receptor without tissue interaction
Answer: C
Explanation: Differential absorption means that different tissues (e.g., bone vs. lung) absorb
or transmit x-ray photons to different extents. These variations in absorption produce the
structural representation of the anatomy on the image receptor.
Question 3
In radiography, beam attenuation refers to:
A. An increase in photon energy after passing through tissue
B. The complete elimination of scatter radiation
C. The reduction in energy or number of photons in the primary x-ray beam due to photon
interactions with atomic structures, involving absorption and scattering
D. Only the scattering of photons without any energy loss
Answer: C
Explanation: Attenuation encompasses both absorption (complete removal of photons) and
, scattering (change in direction with energy loss). It reduces the intensity and energy of the
primary beam as it passes through matter.
Question 4
How does the photoelectric effect contribute to image formation?
A. It causes photons to change direction without being absorbed, increasing noise
B. It involves total photon absorption based on the incoming x-ray photon's energy and the
atomic number of anatomic tissue, contributing to image contrast
C. It only occurs in soft tissue and reduces image sharpness
D. It produces high-energy scatter that improves image brightness
Answer: B
Explanation: The photoelectric effect results in complete photon absorption, predominantly
in tissues with higher atomic numbers (e.g., bone). This differential absorption is a primary
source of radiographic contrast.
Question 5
Compare the photoelectric effect and Compton scattering.
A. Both involve total photon absorption and produce identical contrast
B. Photoelectric effect ejects inner-shell electrons with complete absorption; Compton
scattering ejects outer-shell electrons with photon energy loss and directional change
C. Photoelectric effect occurs only in soft tissue; Compton scattering occurs only in bone
D. Both interactions are independent of x-ray energy and tissue atomic number
Answer: B
Explanation: The key distinction is that the photoelectric effect absorbs the entire photon,
while Compton scattering only partially transfers energy and redirects the lower-energy
photon, contributing to scatter radiation.
Question 6
What is coherent scattering and its relevance in radiography?
A. A high-energy interaction that produces the majority of image contrast
B. A low-energy x-ray interaction, not considered important in radiography as it does not
contribute useful information but does contribute to patient and others' radiation exposure
C. The primary interaction responsible for photoelectric absorption
D. An interaction that completely eliminates scatter radiation from the image
Answer: B
Explanation: Coherent scattering (also called classical or Rayleigh scattering) involves a
change in photon direction without energy loss or ionization. It adds no diagnostic
