Principles Of Radiographic Imaging Final Review

The recorded detail of a structure is dependent on Correct! all of the above. the placement of the body in relationship to the film. its position within the body. the size of the part. {Ans: }As subject density ____, image receptor exposure ____. Correct! increases; decreases increases; remains the same decreases; decreases increases; increases {Ans: }All of the following are true of Compton scatter EXCEPT: *It contributes no meaningful information the final image. * Its production increases as tissue density increases. *It is a significant contributor to occupational radiation exposure. *It is not a factor of exposure technique selection. {Ans: Its production increases as tissue density increases.}Soft tissue absorbs more radiation and produces more scatter than bone. Correct! False True {Ans: }The shutters of a collimator reduce stem radiation. Correct! all of the above. reduce penumbra. regulate field size. {Ans: }Attenuation is greater for elements with more ____ with which the photons may interact. protons neutrons positrons Correct! electrons {Ans: }As the kilovoltage increases, the percentage of photons that undergo a ____ interaction will decrease. characteristic Correct! photoelectric Compton coherent {Ans: }Shape distortion can be the result of a patient's body habitus.
