what mag modes are available? - correct answer if you have a 16" II, you can have 12,9,6, and 4.5 " Compton effect - correct answer hits the outer electron, incomplete transfer of energy, electron released and a low energy xray is deflected photoelectric absorption - correct answer x-ray totally absorbed by inner shell electron, x-ray overcomes binding energy and knock out the electron and an outer shell electron takes it place. When the outer electron moves to its new place, a charac...

What is the lost of some energy from the x-ray beam as it passes through the tissue being imaged? - Beam attenuation The photoelectric affect involves the removal and or ejection of an electron. This process of removing an electron from an atom is? - Ionization When the x-ray photon strikes an atom within the tissue being imaged and looses "all" of it's energy to an "inner" shell electron of an atom the photon is set to have been ________ to undergo ________? - absorb; photoelectric i...
