QUESTIONS AND SOLUTIONS
◉prime. Answer: The factors that affect XR emission under the
direct control of the radiographer are called_ factors
◉beam quality. Answer: Milliamperage-second (mAs) directly
affects all of the following EXCEPT
◉mA & filtration. Answer: The factors that directly affect XR
quantity are
◉kVp & beam filtration. Answer: The factors that directly affect XR
quality are
◉6.3 x 10(18). Answer: If 1 coulomb is equal to 6.3 x 10(18)
electron charges, how many electrons flow from cathode to anode 1
second
◉6.3 x 10(15). Answer: If 1 ampere equals a flow of 6.3 x 10(18)
electrons per second, how many electrons flow from cathode to
anode in 1 milliampere?
, ◉increase 2-fold. Answer: As the mA doubles, the number of
electrons flowing from cathode to anode
◉XR beam quantity. Answer: The product of tube current 7
exposure time is equal to
◉change the mAs from 15-21 mAs. Answer: In order to increase
radiographic film density by 40% the radiographer would
◉directly proportional. Answer: The relationship between mAs &
exposure is
◉the reciprocity law. Answer: The reaction of a photographic film to
light is equal to the product of the intensity of the light and the
duration of the light exposure.
◉cause the electrons to travel faster from cathode to anode. Answer:
Increasing the kVp for an exposure will
◉greater energy. Answer: Increasing the energy of an incident
electron will result in the production of an XR photon with
