X-ray Tubular
RAD to my Radiation
100
This has a positive charge.
What is a Proton?
100
Controls the QUALITY or penetrating power of the photons in the x-ray beam
what is kVp
100
These two types of interactions occur inside the x-ray tube
What is Bremsstrahlung and Characteristic
100
Roentgen discovered x-rays while working with this tube.
What is a Crooke's tube?
100
This is a small bundle of electromagnetic energy.
What is a photon.
200
This has a negative charge.
What is an electron.
200
what is the product of the number of electrons and the amount of time in seconds (tube current) the x-ray tube is activated.
what is mAs
200
This type of interaction is the most important between x-ray photons and the atoms of the patients body for producing useful images.
what is Photoelectric Absorption
200
This forms the basic structure of the X-ray tube.
What is a Pyrex glass envelope?
200
This is a German work that means breaking or slowing.
What is Bremsstrahlung?
300
These are the building blocks of all matter.
What are atoms?
300
to decrease our patients dosage which technique would the limited technologist want to decrease?
What is mAs
300
This type of interaction is responsible for most of the scattered radiation produced during a radiologic procedure.
What is Compton Scatter
300
This is the source of electrons at one end of the tube.
What is a filament?
300
If we set the kVp to be ABOVE 70, 15% of the x-ray beam will be this type of interaction
What is characteristic radiation?
400
These two atoms are in the nucleus?
What are protons and neutrons
400
Particles associated with electromagnetic radiation that have neither mass nor electric charge are
what is x-ray photons
400
What is Pair Production
400
This end of the X-ray tube is also referred to as the "target."
What is the anode?
400
The x-ray beam is made up of many different wavelengths and energies.
What is heterogeneous?
500
What has an atomic number of 74?
What is tungsten?
500
A device for removing long wavelength radiation from the primary x-ray beam
What is a 2.5 aluminum filter
500
what is Photoelectric Absorption
500
This is referred to as an "electron cloud," where heat speeds up the movement of electrons causing them to move further from the nucleus.
What is thermionic emission?
500
This type of interaction forms INSIDE the x-ray tube occurs when an incoming electron removes an inner orbital electron from the tungsten atom, creating a "hole" in the K-shell and an outer-shell electron drops to fill the hole, and a photon is emitted.
What is the formation of characteristic radiation?
