LMRT Core Exam Question
recoil electron & the scattered photon - Answer During Compton scattering, the
incident photon energy is divided between the
greater energy is imparted to the recoil electron - Answer As the angle of
deflection is increased from 0-180 degree
radiation fog - Answer Unwanted radiographic image densities caused
predominantly by scattered photons is called
annihilation reaction - Answer In which process is matter converted back to
energy?
photoelectric absorption - Answer Which of the following interactions has a
significant impact on the XR image?
Compton Scattering - Answer In the human body,_ is the predominant interaction
through most of the diagnostic XR range
greater Compton scatter interactions - Answer In effort to decrease the mAs of an
exposure, the15% rule of kVp change may be considered. Changing the original
kVp of 84 using 15% rule will have what impact
, LMRT Core Exam Question
increasing atomic # of the absorber - Answer The incidence of the photoelectric
effect increase with
radiographic contrast - Answer Photons that pass though the body unaffected
produce
Compton - Answer The atomic interaction that produces scatter radiation is
patient - Answer The greatest source during a radiographic examination is the
for part thickness above 10 cm - Answer As a general rule, a radiographic grid is
employed
a grid is a series of lead strips that alternate w/radiopaque interspace strips -
Answer Which statement about radiographic grids is incorrect?
blur out the radiopaque strips - Answer the purpose of moving the grid during the
radiographic exposure is to
