About this Program

This program will provide a history of early fluoroscopes, and the basic principles of fluoroscopic function. The components, particularly the image intensifier, and how they convert x-rays to visible light will be discussed. Modern fluoroscopes have new features that technologists need to be aware of; these advanced elements will also be covered. The importance of the use fluoroscopy for various imaging procedures will be covered as well.


Principles & Applications

Limitations Early Fluoroscopes

  • Fluorescent screens

  • Radiologist Dose

Principles of Fluoroscopy

  • X-ray Tube, Low Tube Current
  • Fluorescent Screens
  • Noisier, Real-time Images

Modern Features

  • AEC
  • Last Image Hold/Frame Averaging
  • Electronic Collimation


  • GI Studies
  • Myelography
  • Arthrography


Educational Objectives

At the completion of this program, participants will be able to:

  • Recall how an x-ray image is converted to visible light
  • List the sources of image contrast
  • Describe the limitations of early fluoroscopes
  • Select the typical tube energy (kVp) range for fluoroscopy
  • Identify the various components of a fluoroscope

How it Works:

  • Your On Demand CE activity that you purchased will be located in your “My Account” section once you log into the MTMI Website.
  • You have three attempts to pass each quiz.
  • You must earn a score of 75 % or higher.
  • Credit is recorded the day you submit and pass the quiz and is determined using Central time.
  • You have 30 days to complete and pass the quiz.
