About this Program

Most digital radiography seminars discuss how the equipment works and the physics behind it. This webinar is designed to give radiographers practical knowledge to help them use their CR, DR, C-Arm and fluoroscopic equipment. With over 340 images and photos, this presentation will feel like a "hands-on" workshop.

This webinar will confront the universal problems and concerns with digital radiography. You will learn why you should be using 15-20 kVp higher and about 1/3 the mAs required for film/screen. Little training exists to provide an understanding of the use of Exposure Index (EI) numbers and ranges. These will be discussed throughout the webinar. 

In addition, we will be discussing many fluoroscopic topics which have never been covered before.  Topics covered are: the location of the least amount of scatter with the c-arm in the lateral position in OR, the difference in scatter protection between .25mm, .375mm and .50mm lead aprons,  the location of scatter in a fluoro room in the AP position, and the Organization for Occupational Radiation Safety in Interventional Fluoroscopy (ORSIF).


This webinar satisfies your CE requirements for:

  • 4 of the 24 X-ray CEs in digital radiography (required for all CRTs)
  • 4 of the 24 CEs in radiation safety for the clinical use of fluoroscopy (for fluoroscopy permit holders)

Educational Objectives

At the completion of this webinar, attendees will be able to:

  • Select appropriate technical factors to optimize acquiring a diagnostic image, consistent with ALARA.
  • Describe at least three different ways to critique a digital image.
  • Identify what is needed to use a technique chart for digital systems.
  • Describe why a Ferlic Filter is beneficial on a cross-table lateral hip view.
  • Explain why Off Focus radiation shielding your patient is so important.
  • Outline the legal implications of not marking images, post processing collimation and changing algorithms.
  • Describe the areas of least radiation using the c-arm in OR for a lateral hip.
  • Identify the type of lead apron that offers the best protection in fluoroscopy.
  • Review the location of scatter radiation for an AP patient using a fluoro room.
  • Recognize the importance of ORSIF(Organization for Occupational Radiation Safety in Interventional Fluoroscopy)
