Factors that affect xray Quality Flashcards
as the kvp increased the xray beam qaulity is ___
increased
increasing the kVp, so is beam qaulity, but qauntity is ______
decreased
increasing filtration, _____the quality of an xray beam
Increases
in periodic table __ is chosen because it is efficient in removing low energy
Aluminum (z=13)
as filtration is increased, so is beam quality but the quantity is ____
decreased
what are the types of filtration
inherent filtration
added filtration
total filtration
refers tot he filtration that is permanent n the path of the xray beam
Inherent filtration
describes the filtration that is added to the port of the xray tube
Added Filtration
is the material primarily used for this purpose to absorbs the low energy photon while allowing higher energy to exit
Aluminum
in the xray beam is the sum of the added filtration and the inherent filtration
Total Filtration
a special filter to be added to the primary beam to alter its intensity
Compensating Filter
these type of filter are used to image anatomic areas that non uniform in make up and assist in creating a radiographic image with more uniform density
Compensating Filter
the most common type of compensating filter
Wedge Filters
performs a similar function to the wedge filter but designed differently it has a double wedge
bilateral wedge filter / Trough filter
shaped filters are used with computed tomography imaging systems to compensate for the shape of the head or body
