| Question | Answer |
|---|---|
| What is Bremsstrahlung radiation? | When a high-speed electrons path is changed and the loss of kinetic energy is transferred into the form of an x-ray photon (D.A. Saia, Rad Prep) |
| An easy way to remember Bremsstrahlung radiation? | Bremsstrahlung radiation= braking radiation, ( the electron is slowed down and gives of x-rays that can have multiple reactions) (D.A. Saia, Rad Prep) |
| Comprises 70%-90% of the x-ray beam | Bremsstrahlung radiation (D.A. Saia, Rad Prep) |
| interaction where a high-speed electron ejects a k-shell electron from it's orbit and other electrons move to fill it's vacancy emitting an x-ray photon | Characteristic radiation (D.A. Saia, Rad Prep) |
| How much energy does characteristic radiation require | 70keV (D.A. Saia, Rad Prep) |
| Is Characteristic or Bremsstrahlung radiation useful in producing radiographs? | Bremsstrahlung (D.A. Saia, Rad Prep) |
| x-rays have what kind of frequency and wavelength in the electromagnetic spectrum? | High frequency, short wavelength (D.A. Saia, Rad Prep) |
| where do x-rays fall on the energy spectrum? | electromagnetic energy (D.A. Saia, Rad Prep) |
| Principle factor that controls quantity of x-ray photons | mAs (D.A. Saia, Rad Prep) |
| Principle factor that controls quality of x-ray photons | kV (D.A. Saia, Rad Prep) |
| Three ways x-ray photons can interact with matter? | 1- Pass through 2- Be absorbed 3- Scatter (D.A. Saia, Rad Prep) |
| Changes mechanical energy to electrical energy | Generator (D.A. Saia, Rad Prep) |
| Changes electrical energy to mechanical energy | Motor (D.A. Saia, Rad Prep) |
| current with constant changing of polarity and amplitude | AC/ Alternating current (D.A. Saia, Rad Prep) |
| operates on the principle of self-induction | Autotransformer (D.A. Saia, Rad Prep) |
| process that uses solid state diodes to convert AC to DC | Rectification (D.A. Saia, Rad Prep) |
| positive electrode of x-ray tube where x-ray photons are created | Anode (D.A. Saia, Rad Prep) |
| negative electrode of x-ray tube where electrons are directed toward target spot | Cathode (D.A. Saia, Rad Prep) |
| T/F the stator is outside the glass envelope? | True (D.A. Saia, Rad Prep) |
| T/F Is the rotor inside the glass envelope? | True (D.A. Saia, Rad Prep) |
| Atomic number of Tungsten (W) | 74 (D.A. Saia, Rad Prep) |
| Principle that states that the effective focal spot is always smaller than the actual focal spot | Line Focus Principle (D.A. Saia, Rad Prep) |
| T/F The production of x-rays is a very efficient process | False, Most of the energy used to create x-rays is converted to heat. Only 0.2% is converted into x-rays. (D.A. Saia, Rad Prep) |
| 3 reasons why Tungsten is a good target material | 1- High atomic number (74) 2- High melting point (3410 Celsius) 3-Thermal conductivity to dissipate heat (D.A. Saia, Rad Prep) |
