About this Program

Protocol and dose optimization are of great importance in computed tomography. It is central to the safe and appropriate use of CT and is now included in some regulations including the standards of accrediting bodies. Medical physicists have a critical role in helping facilities control radiation dose and improve CT protocols to provide valuable clinical information while minimizing risk. To provide support for facilities, physicists must understand the scanner features, and how they impact image quality and dose. This webinar course will provide an opportunity for medical physicists to increase their understanding of computed tomography, advanced features of scanners, and the accreditation process. Manufacturer-specific information on scanner features will be presented. This course will provide 12 hours of continuing education credit.

Educational Objectives

At the completion of this course attendees will be able to:

  • Review the components of multi-detector CT units
  • Summarize how the use of contrast can affect image quality
  • Explain how radiation dose from CT units is measured and controlled.
  • Outline the development and optimization of CT protocols.
  • Discuss the workflow and CT protocol from the technologist perspective.
  • Recognize the impact of advanced scanner features for various clinical applications.
  • Design an effective QC program for technologists and the physicist.
  • Describe how dual-energy techniques affect radiation dose.
  • Employ the programs, testing requirements and application processes of accreditation bodies.
