  2. Which of the following x-rays would be most likely to undergo classical scattering?
    5 keV
  3. Which of the following interactions contributes to image noise?
    Compton scattering
  4. During the compton effect, most of the incident x-ray energy is given to which of the following?
    Scattered x-ray
  5. After compton scattering, the scattered x-ray has
    longer wavelength
  6. Compton interaction affects the image by increasing which of the following?
    Noise (fog)
  7. The probability that an x-ray will interact with an outer shell electron is influenced principally by:
    The energy of the incident x-ray
  8. The compton interaction involves so called "unbound" electrons because:
    The have a very low binding energy
  9. Which of the following is the x-ray interaction that does not cause ionization?
    calssical scattering
  10. The photoelectric effect is principally associated with which of the following?
    Absorbtion of an x-ray
  11. The radiographic image is formed principally by which of the following?
    Photoelectric interactions
  12. The photoelectric effect is:
    The complete absorbtion of an x-ray eith the subsequent emission of an electron
  13. Differential absorbtion, although a complicated process, is basically the result of differences between:
    photoelectric effect and transmission
  14. At what approx x-ray energy is the probability of a photoelectricinteraction in soft tissue equal to the probability of a compton interaction?
  15. Differential absorbtion is:
    The difference betweenh those x-rays that are absorbed and those that are transmitted
  16. As kVp increases, the realative number of x-rays:
    that interact with tissue decreases
  17. High kVp in chest radiography will
    reduce patient dose
  18. Increasing kVp in x-ray imaging will:
    reduce skin dose
