ACCURATE ANSWERS ASSURED SUCCESS
⩥ What is the focal spot? Answer: Area of the target which electrons
interact
⩥ What rotates during exposure? Answer: Anode
⩥ What does the small filament do? Answer: Provides greater image
detail
⩥ The effective focal spot is smaller than the? Answer: Effective focal
spot size
⩥ Radiation intensity is greater at the cathode and less at the anode end
of the x-ray beam because of the? Only significant when using entire
beam (14x17 in at 40 or 72 in) Answer: Anode Heel Effect
⩥ Placing thinner parts under the anode portion of the x-ray beam would
result in? Answer: Uniform radiographic density
,⩥ Higher kVp would do what to the penetration? Answer: Increase
penetration
⩥ Higher kVp should be used for what type of body parts? Answer:
Larger or more dense body parts
⩥ The pyrex class envelope of the x-ray tube supports what? Answer:
Electrodes and maintains a vacuum
⩥ What does filtration do? Answer: Removes low energy x-ray photons
from the x-ray beam that cause unnecessary patient expsoure
⩥ Radiation scatter production is increased when? Answer: The
collimator is wide open, the kVp is too high, or the body part is to thick
⩥ Quality of the beam is? Answer: kVp
⩥ Directly proportional to the quantity of the x-ray beam? Answer: mAs
⩥ The focal spot size may effect the? Answer: Sharpness of the image
⩥ AEC Answer: Requires accurate positioning, require use of bucky,
provides consistent radiographic density
, ⩥ Using 200 mA at 0.25 sec results in an mA value of? Answer: 50 mAs
⩥ SID Answer: Inversely related to image density and beam intensity
⩥ mA and time Answer: together determine the total quantity of
radiation produced and has a directly proportional relationship to image
density
⩥ What would you increase by 15% to double image density? Answer:
kVp
⩥ What is the primary factor to control image contrast? Answer: kVp
⩥ What would you decrease to decrease the penetrating ability? Answer:
kVp
⩥ Increasing the SID will result in? Answer: A lower patient dose
⩥ What factor is usually standardized and does not vary from pt to pt?
Answer: SID
