RADIOGRAPHIC IMAGING AND EXPOSURE
EXAMINATION TEST 2026 COMPLETE
QUESTIONS AND ANSWERS GRADED A+
◉ any unwanted brightness level on the image. Answer: artifact
◉ the reduction in intensity of a radiation beam as it passes through
a substance.. Answer: attenuation
◉ the amount of luminance (light emission) of a display monitor.
Answer: brightness
◉ as an energy beam is deposited within the atoms comprising the
tissue, some photons are completely absorbed. Answer: absorption
◉ An interaction that occurs with low energy x-rays, typically below
the diagnostic range. The incoming photon interacts with the atom,
causing it to become excited. The x-ray does not lose energy but
changes direction.. Answer: Coherent scattering
◉ Photon hits an outer shell electron, ejecting it - the ejected
electron leaves the atom - the photon continues on an altered path
,with less energy than before and may leave the body as scatter.
Answer: Compton effect
◉ The ability of the image receptor to distinguish between objects
having similar subject contrast. Answer: contrast resolution
◉ xrays will react differently depending on what type of tissue its
going through (ex: fat vs muscle, bone vs air). Answer: differential
absorption
◉ loss of accuracy - misrepresentation. Answer: distortion
◉ the range of exposure intensities an image receptor can accurately
detect. Answer: dynamic range
◉ shape distortion - images of objects that appear longer than the
true objects. Answer: Elongation
◉ composed of both scattered and transmitted radiation. Answer:
exit/remnant radiation
◉ exit/remnant radiationfl. Answer: When the attenuated x-ray
beam leaves the patient, the remaining x-ray beam is referred to as
_____?
, ◉ continuous beam of xrays to create images of moving internal
structures and viewed in real time. Answer: fluoroscopy
◉ aka: scatter radiation. Answer: fog
◉ masks the desired brightness on the image. Answer: fog
◉ shape distortion - images that appear shorter than the true
objects. Answer: Foreshortening
◉ different shades of gray that can be stored and displayed by a
computer system. Answer: Grayscale
◉ fewer shades of gray - greater differences between gray shades -
low mAs & high kVp. Answer: high contrast image
◉ The device that receives the energy of the x-ray beam and forms
the image of the body part. Answer: Image Receptor (IR)
◉ The exit or remnant radiation leaving the patient interacts with
the IR - is not visible. Answer: Latent (invisible) image
