Course Description

Prior to being able to perform, refer and interpret three dimensional radiographic images, you must know about the technology, radiation physics and radiation protection rules that go hand-in-hand with CBCT. Patient selection and case selection will be discussed as not every patient or pathology can and/or should be exposed to the ionizing radiation of the CBCT. Once this has been established, we will learn how to better interpret the images and to recognize and avoid the pitfalls and artifacts that can occur on these images.

Course Objectives

As a result of attending this course, you will be able to:

  • Understand the basic structure and function of CBCT.
  • Describe how CBCT machine works, including patient preparation and positioning.
  • Determine how variables (field of view, kVP, mA, scan time) and artifact affect the image.
  • Understand multiplaner reformatting.
  • Discuss the effective dose associated with CBCT, and how effective dose is affected by equipment and patient related factors.
  • Communicate dose and risk of CBCT to staff and patients effectively.
  • Understand the patient selection criteria.
  • Navigate a volumetric CBCT image.
  • View and analyze CBCT in a systemic manner.
  • Recognize the normal anatomy and normal variation of anatomy appearance on CBCT.
  • Explain the CBCT appearance of pathology.

Course Outline

  • 8:35am – 10:00am: How does CBCT work
  • 10:15am – 12:00pm: Radiation dose and risk in CBCT. Indication for CBCT
  • 1:00pm – 2:15pm: Anatomy on CBCT images
