fluoroscopy

• What are the main components of the image intensifier in fluoroscopy?

  • Input screen
  • Input window
  • Input phosphor
  • Photocathode
  • Electron optics
  • Output screen
• What are the effects of magnification in fluoroscopy?

  • Improves spatial resolution
  • Reduces minimization gain
  • Increases patient dose due to ABC adjustments
• what is fluoroscopy 


  the capture of dynamic sequences of x ray images in real time
• within the image intensifier explain the process that are occurring within

  the input phosphor:

  • x ray photons are converted to light photons
• within the image intensifier explain the processes that are occurring within:


  the photocathode :

  • light photons are converted to electrons
• within the image intensifier explain the processes that are occurring within

  the electron optics:

  • electrons are accelerated
• within the image intensifier explain the processes that are occurring within 


  the output phosphor :

  • electrons are converted into light
