Optimizing CT Protocols and Dose
8 Hours ARRT Category A Credit
Christine Eckenrod, RT(R)(CT)(MR)
About this Seminar
In the past several years, significant advances in the technology of Computed Tomography (CT) have occurred. These developments have driven an expansion in the clinical applications of CT and an increase in the number of CT scanners. Opportunities for CT technologists have grown as a result. Never has the importance of CT dose control been so prevalent in the public as it is today. The competent CT technologist must have the most current information in order to provide quality patient care.
Educational Objectives
At the completion of this seminar,
participants will:

  • Understand the evolution of the technology involved in the acquisition of CT images.
  • Discuss the technologists' role in radiation education.
  • Discuss ALARA and dose creep.
  • Discuss volume acquisition scanning - pros and cons
  • Appreciate radiation safety and dose considerations needed to conduct CT examinations safely.
  • Discuss protocol optimization/dose - using parameters to control dose.
  • Discuss the various applications of multi-detector scanning.
  • Discuss the optimization of formatted images.

Christine Eckenrod RT(R)(CT)(MR)
Christine started her medical imaging career when she graduated from the Altoona Hospital School of Radiologic Technology in 1986. In 1993, she specialized as a CT technologist followed by MRI in 2004. She is currently employed as a CT/MR technologist with Alliance Imaging, INC. She has extensive experience in CT training and protocol development. Christine presents a lighthearted, easy to understand review of all of the basics of CT Scanning while reviewing the content specifications for the ARRT CT registry. You will be sure to enjoy the presentation while learning or refreshing your knowledge in the field of CT Imaging.
