A rheostat adjusts the current by adjusting
resistance
The actual amount of mAs that is used for that image displayed immediately after the exposure
mAs readout
refers to the shortest time that the system can produce
minimum response time
refers to the maximum length of time the X-ray exposure will continue when using an AEC system
back up time
allows the radiographer to adjust the amount of preset radiation
density control/master density
