|
Composed of anode (+) and cathod (-) in a vacuum within glass envelope in a lead housing
|
X-ray Tube
|
|
|
"quality factor" which regulates voltage differential between the anode and cathode.
|
Kilovotage kVp
increase kVp increase darkness |
|
|
time in fraction of a second during which anode is possitively charged
|
exposure time
increase time increase electrons from cathode to anode and increase # of x-ray photons |
|
|
what is the importance of mAs
|
it reduces motion blur
mAs= milliamperage x time use the highest milliamperage setting and lowest time setting to get mAs |
|
|
"quality factor" which controls the quantity of electrons boiled off the filament of the x-ray tube
|
milliamperage mA
increase mA increase darkness lower mA lighter radiograph |
