  1. Increase in collimation from a 14x17 field size to 4x4 field size would result in
    decrease in IR exposure
  2. an increase in added filtration
    decreases in IR exposure
  3. a decrease in time from 0.1s to 0.02 would result in
    a decrease in IR exposure because time is part of mas if any part of mas decreases less photons IR and radiographic density decreases
  4. an increase in 5% of the kvp (in the lower kv range) result in
    increase in IR exposure
  5. A change in mAs from 50-58 would result in
    increase of IR exposure
  6. a change from a 0.5 in to a 10 OID would result in
    decrease in IR exposure
  7. a change in grid ratio from a 5:1 to an 8:1 would result in
    a decrease in IR exposure
  8. a change in focal spot size from large to small would result in
    no change to IR exposure
  9. a change f/s speed from 800 to 100
    decrease in IR exposure because it is going from a higher speed to a slower speed the higher or faster the film speed the faster the image turns black
  10. a change in mAs from 30-45 would result in
    increase in IR exposure
  11. a change in configuration of the generator from a high frequency unit to a full wave (1 phase -2 pulse) to would result in an image with too little density/IR exposure
    T or F
    True
  12. t or f
    does scatter add density or exposure to a radiograph/IR
    T
  13. an increase in kvp will increase the number of photons reaching the IR
    t or F
    T
  14. window level describes digital processing that produces changes in brightness
    t or f
    T
  15. there is an direct relationship between tissue thickness type and density/IR exposure
    t or f
    t
  16. a decrease in SID from 72 to 56 would require a reduction in mAs by half
    t or f
    true
  17. the relationship between mAs and SID is inversely proportional to the square of the distance
    t or f
    F
  18. when CR or DR images are underexposed radiographic noise or quantum mottle may be apparent. What change would best correct this
    increase mas
  19. an additive disease process would require ______ to maintain IR exposure of radiographic
    an increase in kvp
  20. an increase IR exposure or radiographic density will most likely result from a decrease in:
    grid ratio
    kvp
    focal spot size
    mas
    grid ratio
  21. which two things would decrease IR exposure or radiographic density
    a decrease in kv selection and increase SID
