Remnant X rays are those that <<answer>>..Exit the patient
Which factor that affects scatter radiation can be controlled by
the rad tech <<answer>>..Field size
As kVp increases, scatter radiation production will
<<answer>>..Increase because of more Compton interaction
What is the approximate percentage of x rays that are
transmitted through a patient <<answer>>..1%
At high kVp (125 kVp), most x rays are
<<answer>>..Transmitted through the body with interaction
When kVp is increased with a compensating reduction in mAs,
what is reduced <<answer>>..Patient dose
,If a constant optical density is maintained while kVp is increased
patient dose will <<answer>>..Decrease
As field size is increased, scatter radiation
<<answer>>..increases
What are devices designed to reduce the level of scatter
radiation that reaches the image receptor <<answer>>..Beam
restrictor, collimator, compression device, diaphragm
Scatter radiation reduces radiographic contrast quality by
changing <<answer>>..Contrast
X rays that the technologist would like to have interact with the
IR are those that are <<answer>>..Transmitted in the body
As kVp is increased from 70 to 80 reaching the IR, there will be
higher <<answer>>..Scatter Radiation
Image forming x rays consist of which following type that
emerge from the patient in the direction of the IR
<<answer>>..Transmitted X rays
As kVp increases from 70 to 90, if all other factors remain
constant, the number of absorbed x rays <<answer>>..Will
decrease
,What increases as the field size of the x ray beam increases
<<answer>>..Scatter Radation
In general, as the thickness of the anatomy for which
radiographs are made increases <<answer>>..kVp increases
Which process is most responsible for the production of scatter
radiation <<answer>>..Compton effect
Which of the following are beam restricting devices
<<answer>>..A cone, PBL device, variable aperture collimator
Which is the simplest of all beam restricting devices
<<answer>>..aperture diaphragm
Which of the following devices is normally designed to limit off-
focus radiation <<answer>>..first stage shutters of a variable
aperture collimator
Off-focus radiation results when <<answer>>..projectile
electrons do not strike the focal spot
Cone cutting occurs when <<answer>>..the axis of the cone,
tube and IR are not aligned
If a fixed aperture, rectangular, beam restricting device is used
an unexposed border should be visible on <<answer>>..all four
sides of the radiograph
, A properly designed, light localizing, variable aperture collimator
requires <<answer>>..light field/x ray beam coincidence
Radiographic cones and cylinders are used principally to reduce
<<answer>>..Scatter radiation
Which of the following are the two general types of devices
designed to control scatter radiation <<answer>>..grids and
beam restrictors
When a diaphragm is used a 1 cm unexposed border should be
visible <<answer>>..on all sides
PBL stands for <<answer>>..Positive Beam Limitation
A diaphragm is machined to just match IR size. If an unexposed
border is required on a radiograph, the diaphragm opening will
<<answer>>..have to be reduced
An aperture diaphragm is designed for 25cm x 30cm film. If the
SID is 100 cm and the Source to Image diaphragm Distance is
10 cm, what size should the opening of the diaphragm be
<<answer>>..2.5cm x 3.0 cm
The principal reason for using a grid is to <<answer>>..improve
image contrast
