- The thicker body part needs to be positioned on the cathode(-) side of the tube so the most intense portion of the beam penetrates through the thickest area of the part.

# data[].attributes.body
Variation of x-ray intensity along the longitudinal axis of the tube.
Called this due to the x-ray photons having to pass through the "heel" of the anode(+). This Causes the anode side of the photon beam to lose intensity before reaching the object or image receptor.

# data[].attributes.body
- Made of lead lined steel
- Supports Tube
- Cools Tube with insulating oil
- Also insulates tube from high voltage electricity
- Primary beam exits through opening in housing
- A small amount oil contributes to minimal filtration or absorbtion of the x-ray beam when an exposure is made

# data[].attributes.body
- Glass is thinner here
- no vaporized Tungsten
- minimalizes interference of x-rays leaving the tube

# data[].attributes.body
- coated by vaporized Tungsten to help with reducing leakage radiation
- in an oil bath to help cool the x-ray tube
Components:
- Envelope
- Glass envelope window

# data[].attributes.body
Most tubes will have a small and large focal spot that receives the electrons from the cathode.
- Made of Tungsten because it's high atomic number increases the probability of ideal photon production.

# data[].attributes.body
- Rotates to ensure that not any one spot will receive successive pulses of electrons
- Disc made of molybdenum while the focal spot is made of tungsten.

# data[].attributes.body
Also made of molybdenum nickel alloy due to it's high melting point and poor conduction of heat.

# data[].attributes.body
- Permits smooth rotation of the anode
- Sensitive to heat

# data[].attributes.body
- Made of copper
- Made to rotate by the device called the stator.

# data[].attributes.body
Set of electric coils that creates a strong magnetic field outside of the glass envelope that causes the rotor to rotate very fast.

# data[].attributes.body
- Positively Charged
- x-ray production occurs here
Comprised of:
- Stator
- Rotor
- Bearings (not pictured below)
- Anode Stem
- Rotating Anode disc
- Focal Spot(s)

# data[].attributes.body
Tungsten(W)is used as the filament material because of it's high atomic number which increases the intensity of x-rays. Tungsten also has a high melting point.

# data[].attributes.body
- Supports filament
- controls trajectory of electrons
- Made of Molybdenum Nickel Alloy due to it's high melting point and poor conduction of heat.

# data[].attributes.body
- Negatively Charged
- Source of electrons(e-)
Comprised of:
- Focusing Cup
- Tungsten filament

# data[].attributes.body
- Cathode
- Anode
- Glass Envelope
