Questions and Answers

What is the primary purpose of filtration in x-ray imaging?

  • To improve image quality
  • To remove short-wavelength photons from the x-ray beam
  • To remove long-wavelength photons from the x-ray beam (correct)
  • To increase patient dose
  • What happens to the long-wavelength photons that are not eliminated from the x-ray beam?

  • They are filtered by the x-ray tube
  • They contribute to the x-ray image
  • They are absorbed by the patient (correct)
  • They are eliminated by the body
  • What is the process of filtration in x-ray imaging?

  • The process of removing long-wavelength photons from the x-ray beam (correct)
  • The process of removing short-wavelength photons from the x-ray beam
  • The process of increasing patient dose
