1kvp and penetrability
increase in kvp = increase in penetrability
215% kvp rule
increase in kvp by 15% = doubling the amount of the blackening of the film
3increase in kvp also increases the energy of the _
xray photons
4penetration of the part
kvp increase = penetrability increase
remnant radiation increase = image quality increase
5xray quality and penetrability
direct relation
6radiation that exits the body and travels in different direction with many energy level
scatter radiation
7danger to the patient and the radiographer, and detriment to the film quality
scatter radiation
8the primary source of the scatter radiation
the patient
9psrxfdp
high penetrability
high scatter rad
high remnant
high xray quality
low film contrast
high density
low patient absorption
10as the kvp increases, the amount of radiation absorbed by the patient is _
reduced
11kvp and contrast
high kvp = low contrast
12controlling factor of radiographic contrast
kvp
13scatter and contrast
high scatter = low contrast
14scatter photons may account for as far as much as _ - _ of the photons exposing the film
50%-80%
