Completar frases Radiation Fill InVersión en línea Fill in the following> por kenneth thomas 1 Characteristic Photoelectric increase Scatter MAS target Compton matter KVP Quantum absorbed Bremsstrahlung noise braking noise Radiation A projectile electron interacts with and knocks out an inner shell electron producing a very unstable atom . In order to stabilize itself , and outer - shell electron fills the vacancy in the inner - shell and in this process , an x - ray is emitted . Radiation A projectile electron interacts with a nucleus which causes an x - ray to be emitted . The electron slows down and changes its direction . This is called " " radiation 85% of photons are Bremsstrahlung and create image on film . Classical ( Film Fog ? low energy ? X - ray ) An interaction between low - energy x - rays and matter causes scatter radiation . The X - ray changes direction but does not lose energy . There is no energy transfer , so there is no ionization . This can occur throughout the diagnostic range and therefore , contribute to film fog . Effect ( most form of scatter ) An interaction between moderate energy x - rays and the outer - shell electrons of matter causes scatter radiation . The outer - shell electron is knocked out which causes a loss of energy and ionizes the atom . This is the primary form of scatter caused by " an interaction of x - ray with . " Effect X - rays in the diagnostic range interact with inner shell electrons , so the x - ray is not scattered but completely . Characteristic x - rays are produced following a photoelectric interaction . Mottle Also known as radiographic . This refers to the random nature in which x - rays interact with the image receptor . If x - rays are produced with just a few photons , the radiographic noise will be higher . A granular or spotty , non - uniformity of the x - ray image results . The use of high , low , and slower image receptors reduce radiographic . Fast screens quantum mottle .
