◉ 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
