LMRT Core Review 2024 WITH SOLUTIONS

LMRT Core Review 2024 WITH SOLUTIONS restrict the XR beam to the clinical area of interest - Answer -As a professional radiographer, the practice of ALARA requires you to 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 radiographic film density - Answer -Kilovoltage is the primary controlling factor of contrast - Answer -Adjustments in kVp should be used to control radiographic kVp - Answer -XR beam penetrability is primarily controlled by
