Density and contrast may be controlled by settings on this. -
ANSWER -Control
panel
Determines the speed of the electrons from the cathode to
the anode which
determines the quality or penetration of the x-ray - ANSWER
-Kilovolt Peak
(kVp)
Dental machines range from 65 to 100 kVp. - ANSWER -True
These electrons slam harder into target producing stronger x-
rays. - ANSWER -
Faster
Higher kVp = more penetration so increasing kVp also
increases what? -
,ANSWER -
Density
High kVp= hard x-rays = high energy= greater penetration
=? - ANSWER -
Greater density but low
contrast
This determines the number of electrons boiled off therefore it
determines the quantity or number of x-rays produced. It does
this by heating the filament. - ANSWER -Milliamperage (mA)
More x-rays make a darker image so increasing mA would do
what? - ANSWER
-Increases
density
Dental x-ray machines vary from 7-15 mA. - ANSWER -True
This type of mA setting requires less time to make an
image on a film. -
ANSWER -
Higher
This prevents patient discomfort and movement. - ANSWER -
Quicker exposure
Federal regulations for dental x-ray machines require
them to have an
, aluminum equivalent filter of what? - ANSWER -
1.5 to 2.5 mm
This is added to the tubehead to shrink the size of the beam. -
ANSWER -Lead
collimator
This shape of lead collimator is preferred. - ANSWER -
Rectangular
Federal regulations mandate dental x-rays must be collimated
to how large? -
ANSWER -2.5
inches
At points distant from a common source of x-radiation,
the intensities of
radiation at these points vary inversely as the square of
their respective
distances from the x-ray source. - ANSWER -Inverse
Square Law
As you move away, the intensity is greatly what? - ANSWER -
Reduced
The two theories of biological harm. - ANSWER -Direct and
Indirect Theory
Damage happens when photons actually hit critical parts of a
cell. - ANSWER -
