filtration Flashcards
the process of elimination undesirable low-energy photons by inserting absorbing material
filtration
filtration that is the result of the composition of the tube and housing is often called
inherent
any filtration that occurs outside the tube and housing and before the image receptor
Added filtration
filter that uses tow or more materials that complement one another in their absorbing abilities?
a) compound
b) compensating filter
a) compound filtration
filters that evens radiographic density with parts that are uneven tissue thickness or density
a) compound
b) compensention
b) compensation
total filtration is a combination of what
inherent + added
what is considered the standard material for filtration ?
