QUESTIONS AND ANSWERS WITH
COMPLETE SOLUTIONS 100%
CORRECT!!!
Absorption
Answer: The x-ray photons are removed from the beam when their energy is
absorbed by body tissues.
Attenuation
Answer: The reduction in energy or the number of photons in the primary x-ray
beam after it interacts with anatomic tissue.
Coherent Scattering
Answer: An interaction that occurs with low-energy x-rays, typically below the
diagnostic range. The incoming photon excites the atom without losing energy but
changes direction.
Compton Effect
Answer: The loss of energy from the incoming photon when it ejects an outer-
shell electron from the atom. The remaining lower-energy photon changes
direction and may exit the anatomic part.
Compton electron -ANSWER✔✔The electron ejected from an atom during a
Compton scattering event.
contrast resolution -ANSWER✔✔Used to describe the ability of the imaging
system to distinguish between small objects that attenuate the x-ray beam similarly
in digital imaging.
, differential absorption -ANSWER✔✔The difference between the x-ray photons
that are absorbed photoelectrically versus those that penetrate the body.
dynamic range -ANSWER✔✔The range of exposure intensities that an image
receptor can respond to and acquire image data
exit radiation -ANSWER✔✔The attenuated X-ray beam leaves the patient and is
composed of both transmitted and scattered radiation, also called remnant
radiation.
fluoroscopy -ANSWER✔✔The use of a continuous beam of x-rays to create
dynamic images of internal structures that can be viewed on a display monitor.
fog -ANSWER✔✔Unwanted exposure on the radiographic image that does not
provide any diagnostic information.
image receptor -ANSWER✔✔The device that receives the energy of the x-ray
beam and forms the image of the body part
ionization -ANSWER✔✔The removal of an electron from an atom
latent image -ANSWER✔✔The invisible image that exists on the image receptor
before it has been processed
manifest image -ANSWER✔✔The visible image on the exposed film after
processing
