Standard protocol technical factors for a transthoracic lateral position of the shoulder are 80 kVp,, 800 mA, 15 milliseconds and results in an acceptable EI value. The image must be repeated using 300 mA to demonstrate increased blurring.  What time in milliseseconds should be set on the control panel to achieve the same EI value?  Type ms next to your answer.

What x-ray tube component is the source of thermionic emission?

A radiographer follows standard protocol and sets 75 kVp, 6 mAs, 40” SID, for an AP projection of the knee on a direct exposure imaging system.  The Exposure Index number is 1250 and must be repeated.  Calculate the Exposure Index if the radiographer changes the control panel setting to 12 mAs.  Type EI next to your answer.

What is the maximum number of electrons that can occupy the L shell of an atom if it is not the valence shell?

A radiographer sets 60 kVp, 8 mAs on an indirect system for an AP projection of the ankle and results in an  80 Sensitivity Number (S#).  The radiographer repeats the image using 4 mAs, what is the  expected S# with all other factors held constant?  Type S# next to your answer.
