2025/2026 FLUOROSCOPY ARRT EXAM STUDY GUIDE ACTUAL QUESTIONS AND 100% CORRECT ANSWERS what mag modes are available? - Answer -if you have a 16" II, you can have 12,9,6, and 4.5 " Compton effect - Answer -hits the outer electron, incomplete transfer of energy, electron released and a low energy xray is deflected photoelectric absorption - 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 characteristic x-ray is formed what is the product of photoelectric absorption? - Answer -electron flying , characteristic x-ray, and positive ion coherent scatter - Answer -aka Thompson scatter, Rayleigh scatter or classical scatter. xray is absorbed by entire atom and is sent off in another direction with no energy loss does coherent scatter result in patient dose? - Answer -No, this reaction only causes excitation of the atoms shells, but there is not energy transfer nor does the x-ray lose energy ( isotropic) what is the chance of coherent scatter occurring? - Answer -5% attenuation - Answer -the drop of intensity of the beam due to absorption and Need assistance on Online classes, Exams & Assignments?

This negative charge repels and squishes the electrons that are made from thermionic emission how does deceleration occur in electrons? - Answer -the closer to the nucleus the electron is, the more attraction there is and as a result it slows down faster. More energy is transferred to the xray and it has a higher energy as well. If the electron is far, it Need assistance on Online classes, Exams & Assignments? Reach out for instant help!!
