Tube Components
This is the part of the x-ray tube where x-rays are produced.
What is the Focal Track?(Anode)
This percentage of energy from electron interaction becomes heat.
What is 99%?
The focal spot size affects this image quality factor.
What is spatial resolution (detail)?
This device records radiation exposure to the tech.
What is a dosimeter?
This charge difference between cathode and anode accelerates electrons.
What is kVp?
The part that contains the filament and emits electrons.
What is the Cathode?
The rotating anode helps with this important function.
What is heat dissipation?
Lower kVp and higher mAs increases this type of radiation interaction.
What is photoelectric interaction?
What is warm it up?
This effect causes the emission of electrons from the filament when heated.
What is thermionic emission?
This component focuses the electron beam onto the anode.
What is the focusing cup?
These two materials are often used for their high melting point and thermal properties.
What is tungsten and molybdenum?
A higher kVp increases this type of radiation interaction.
What is Compton scatter?
This part of the tube housing limits leakage radiation.
What is the lead lining or tube housing?
This causes the anode to rotate.
What is the stator?
The rotating anode is typically made of this metal for heat resistance.
What is tungsten?
Too much heat too fast causes this.
What is Anode cracking?
This term describes the portion of the x-ray beam that actually exits the tube and reaches the patient.
What is the primary beam?
Pitting can damage this part of the tube over time.
What is the anode target?
High-speed electrons are converted mostly into this form of energy.
What is heat energy?
This part encases the entire x-ray tube and provides insulation.
What is the glass envelope?
This system surrounds the tube housing to help remove excess heat.
What is the oil cooling system?
Increasing mA will increase the number of these in the x-ray beam.
What are x-ray photons?
You should never make repeated exposures in rapid succession without allowing this.
What is cooling time for the anode?
This switch setting starts the rotor and heats the filament before exposure.
What is the rotor switch?
