|
Lead
diaphragm / Lead Collimator |
Controls the size and shape of x-ray beam.
|
|
|
Useful Beam
|
Primary beam of radiation.
|
|
|
Port
|
Junction where P.I.D. connects to tube head.
|
|
|
Lead Lining
|
Seals oil into the tube head.
|
|
|
Metal Housing
|
Metal body of the tube head. Protects everything
|
|
|
Milliampere Circuit / Step-Down Transformer
|
Controls the quantity of rays produced. Ranges between 7 and 15 mAs.
|
|
|
K.V.P. / Kilovoltage Peak / Step-Up Transformer
|
Determines the size of wave length. Shorter the wave, more harmful.
|
|
|
Apature Window / Unleaded Glass Window
|
Allows the Bremsstranlung radiation to move towards aluminum filters.
|
|
|
Focal Point / Tungsten Target
|
Focal spot of the anode that converts electrons into x-ray photons.
|
|
|
Anode
|
Positive electrode that converts electrons into x-ray photons. Holds the tungsten target.
|
|
|
Copper Tube
|
Conducts heat away from target
|
|
|
Heat Radiator
|
Cools copper stem
|
|
|
Glass Tube / Coolidge Tube
|
Cooling tube that holds cathode and anode

|
|
|
Aluminum Filter / Disk
|
Filters low-energy, longer x-rays.
|
|
|
Bremsstrahlung Radiation / Polychromatic Beam
|
Radiation of various wave lengths. Results when an electron passes near the nucleus of an atom.
|
|
|
Cathode
|
negative electrode that holds the wire filament and focusing cup. Supplies electrons necessary to generate x-rays.
|
|
|
Focusing Cup
|
Made of molybdenum, holds the coil wire filament and directs the stream of electrons to focus spot.
|
|
|
Coil Wire Filament
|
Turns red hot called " incandescent". Emits thermionic emissions that is moved by kinetic energy.
|
|
|
Electron Cloud
|
Negative charged electrons directed to focal spot.
|
|
|
P.I.D. / Position Indicating Device / Cone
|
Aims and shapes x-ray beams. 16 inch cones are best.
|
