1
New cards

milliamperes (mA)

controls the current flow to the cathode filament at the time of exposure

2
New cards

as mA is increased, filament temperature ____ and the number of electrons released _________

rises, increases

3
New cards

an increase in mA _________ the number of x-ray photons in the primary beam

increases

4
New cards

what will doubling mA also double?

radiographic density and patient exposure

5
New cards

mA percentage to visually see a change in density

30-35%

6
New cards

TRUE or FALSE: mA affects scatter radiation

FALSE

7
New cards

time (s)

factor that controls the length of the exposure

8
New cards

milliampereseconds (mAs)

milliamperes and time are combines and recognized as a single quantitative factor

9
New cards

increase in mAs _________ the number of photons exposing the image receptor

increases
