Test 4 Flashcards
An increase in OID will result in
increased magnification
decreased image detail
A measure of current flow rate in the x-ray tube circuit
ma
radiation exposure is directly proportional to
mAs
an increase in kVp affects the x-ray beam by causing it to
have greater intensity
image detail is affected by
focal spot size
patient motion
al electron cloud surrounding a hot cathode is referred to as a
space charge
the purpose of rotating the x-ray tube target (anode) is to
increase the heat capacity
the container of the vacuum of the x-ray tube is made of
glass
which type of radiation form the x-ray image
remnant
how to find the frequency with wavelength
v = f x wl
what are the SI system of measurement units
Gray
c/kg
sievert
radiation ionizes substances by removing
electrons
reddening of the skin and is a short term effect of radiation exposure
erthema
these effects are random, long term effects from low dose radiation exposure
stochastic
