Occurs when Tungsten vaporizes and builds up in a glass tube.

• Anode Heel Effect

• Arcing

• Line Focus Principle

• Tube Window

This side of the x-ray tube is driven by an Electromagnetic Induction Motor

• Anode

• Cathode

• Filament

• Glass Housing

___________ is when radiation intensity is greater at the cathode side of an x-ray beam and is a byproduct of the Line Focus Principle.

• Anode Heel Effect

• Anode Cooling Chart

• Dual Focus Tube

• Extrafocal X-Rays

X-rays that are produced outside the target/focal spot and reduces image contrast.

• Arcing

• Extrafocal X-ray

• Saturation Current

• Space Charge Effect

A coil of thoriated Tungsten wire that is the source of electrons.

• Protective Housing

• Focal Cup

• Cathode

• Filament

A evacuated tube that contains two electrodes, Cathode and Anode.

• Glass Envelope

• Cathode

• Dual Focal Housing

• Tube Window

_____ describes when x-rays have equal intensities and goes in all directions.

• Isotropically

• Ionization

• Leakage X-Rays

• Line Focus Principle

When x-rays that exit the tube other than the Tube Window:

• Leakage Scatter

• Leakage Radiation

• Inherent Scatter

• Inherent Radiation

The angling of the target on the Anode which makes an effective focal spot that can be created smaller than the actual focal spot describes:

• Isotropically

• Arcing

• Anode Heel Effect

• Line Focus Principle

The point in which a further increase in kVp will not result in a higher mA because all the electrons have been used.

• Line Focus Principle

• Anode Heel Effect

• Space Charge Effect

• Saturation Current
