Anatomy of the X-Ray Machine Flashcards
X-Rays are produced in an _____ _____
X-ray Tube
What are the components of the X-ray tube?
Cathode (negatively charged)
Anode (positively charged)
The ____ provides source of electrons and directs these electrons toward the _____
Cathode, Anode
The filament is constructed of _____ because of the high melting point and high atomic number
Tungsten
Amount of electrical energy being applied to the filament. Describes the number of x-rays produced during exposure.
Milliamperage (mA)
Quantity of electrons released depons on ____ of the filament
Heat
What are the two types of anodes?
Stationary and Rotation
Anode found in dental and small portable radiography units
Stationary Anode
______ acts as a conductor of heat and draws the heat away from the tungsten target
Copper
How are x-rays cooled?
Copper at the base of target, surrounding glass tube with oil
The ____ the focal spot, the less clarity
Larger
______ anode can have small focal spot and still withstand a great amount of heat
Rotating
More x-rays leave tube on ____ side of the tube, therefore the _____ side of the animal should be placed closer to the cathode
Cathode, thicker
The peak energy of the x-rays which determines the quality of the x-ray beam
Kilovoltage peak (kVp)
Process when metal deposits that form on inner lining of glass due to overheating
Arcing
