CHIROPRACTIC LIMITED RADIOLOGY STUDY SET WITH
ACCURATE QUESTIONS AND ANSWERS
4 things that effect shades of grey - ->kvP of beam
>mass density of an object
>Atomic number of objects atom
>thickness of object
-5 types of attenuation - -1 coherent scatter
2 Compton scatter
3 photoelectric effect
4 Pair production
5 photo disintegration
-anatomical view - --as if the patient was facing you
-Right on Left
-typical way that radiologist look at films
-any interaction that removes a photon from the primary beam - -Attenuation
-attenuation of compton scattering - -Deflection
-Attenuation: photoelectric - -Absorption
-Bremsstrahling radiation - -whenever a high velocity electron is suddenly slowed down or stopped
when it strikes matter
-Charateristic Radiation - -15% of beam
-Compton scatter - -one of the interactions of x-radiation with matter in which the x-ray photon collides
with a loosely bound, outer shell electron and gives up part of its energy to eject the electron from its
orbit. the x-ray photon loses energy and continues in a different direction at a lower energy level
-Creates uneven distribution of Xray photons in beam - -Anode heel effect
-Darkest to lightest - -Air
fat
water
bone
metal
-How would we compensate for the difference between patients so we can produce consistent density
films for patients of different sizes? - -Changing Maas with fixed kvP
