LMRT Core Review with 100% complete solutions
restrict the XR beam to the clinical area of interest correct answersAs a professional radiographer, the practice of ALARA requires you to prime correct answersThe factors that affect XR emission under the direct control of the radiographer are called_ factors beam quality correct answersMilliamperage-second (mAs) directly affects all of the following EXCEPT mA & filtration correct answersThe factors that directly affect XR quantity are kVp & beam filtration correct answersThe factors that directly affect XR quality are 6.3 x 10(18) correct answersIf 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) correct answersIf 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 correct answersAs the mA doubles, the number of electrons flowing from cathode to anode XR beam quantity correct answersThe product of tube current 7 exposure time is equal to change the mAs from 15-21 mAs correct answersIn order to increase radiographic film density by 40% the radiographer would directly proportional correct answersThe relationship between mAs & exposure is
