To produce a radiographic image, x-ray photons must pass through _______ and
interact with an _____. - ANSWERTissue
IR
a device that receives the radiation leaving the patient - ANSWERImage Receptor (IR)
The absorption characteristics of the anatomic part are determined by its ________,
_________ ________ of the atoms contained within it, and _______ __________. -
ANSWERThickness
Atomic Number
Tissue Density
Radiation that exits the patient is composed of varying energies and interacts with
the IR to form a ______/________ image. - ANSWERLatent (invisible)
A process whereby some amount of the x-ray beam is absorbed in the tissue and
some passes through the anatomic part. - ANSWERDifferential Absorption
Anatomic parts composed of _____ absorb more x-ray photons than parts filled with
______. - ANSWERBone
Air
As the primary x-ray beam passes through anatomic tissue, it loses some of its _____
(________) - ANSWEREnergy (intensity)
The reduction in the intensity or number of photons in the primary x-ray beam after
it interacts with anatomic tissue - ANSWERAttenuation
2 Distinct processes occur during beam attenuation: - ANSWERAbsorption and
Scattering
Complete _______ of the incoming x-ray photon occurs when it has enough energy
to remove an inner-shell electron. - ANSWERAbsorption
The ejected electron is called a _____________ - ANSWERPhotoelectron
The ejected electron (photoelectron) quickly loses energy by interacting with nearby
________. - ANSWERTissues
The ability to remove (eject) electrons - ANSWERIonization
, Ionization in the diagnostic range is also known as: - ANSWERPhotoelectric Effect
With the photoelectric effect, an ionized atom has a _______ ______ in its inner
shell. - ANSWERElectron Hole
In Photoelectric Effect, An electron from ____ _____ drops down to fill the electron
hole. - ANSWEROuter Shell
In Photoelectric Effect, Because of the difference in binding energies between the
two electron shells, a ________ x-ray photon is emitted. - ANSWERSecondary
A Secondary x-ray photon typically has a very _____ energy and is _____ to exit the
patient. - ANSWERLow
Unlikely
During attenuation of the x-ray beam, the ________________ _______ is responsible
for the total absorption of the incoming x-ray photon. - ANSWERPhotoelectric Effect
Some incoming photons are not absorbed but instead lose energy during
interactions with the atoms of the tissue. - ANSWERScattering
The interaction between diagnostic x-rays and matter. - ANSWERCompton Effect
The loss of energy of the incoming photon occurs when its ejects an _______-
_______ ______ from a tissue atom. - ANSWEROuter-shell electron
The ejected electron is called: - ANSWERCompton Electron or Secondary Electron
During attenuation of the x-ray beam, the incoming x-ray photon may lose energy
and change direction as a result of the _______ ______. - ANSWERCompton Effect
probability is the # of electrons per gram. - ANSWERIn Compton Effect
Interaction that occurs with low-energy x-rays, typically below the diagnostic range. -
ANSWERCoherent Scattering
In coherent scattering, the incoming photon interacts with the atom, causing it to
become _________.
The X-ray does not loose energy it just changes ________. - ANSWERExcited
Direction
*An incoming photon has sufficient energy to eject an inner-shell electron and be
completely absorbed.
*An electron from an upper-level shell fills the electron hole or vacancy
*A secondary photon is created because of the difference in the electrons' binding
energies.
