PRODUCTION AND EXPOSURE WEEK 3
AND 100% CORRECT ANSWERS|LATEST
absorption - ANSWER The x-ray photons removed from the x-ray beam as a result of
the uptake of their energy by body tissues
attenuation - ANSWER Reduction in the energy or 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 interacts with the atom, causing
it to become excited. The x-ray does not lose energy but changes direction
Compton effect - ANSWER The loss of energy of the incoming photon when it ejects
an outer-shell electron from the atom. The remaining lower-energy x-ray photon changes
direction and may leave 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
1
, 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
matrix - ANSWER Combination of rows and columns (array) of pixels that make up a
digital image
photoelectric effect - ANSWER In the diagnostic range, the total absorption of the
incident photon by ejecting an inner-shell electron of a tissue atom.
photoelectron - ANSWER The ejected electron resulting from ionization during the
photoelectric effect
