The Basics of CT – 9 CE Credits

A continuing education course intended to provide technologists with a firm foundation in CT scan basics, in everything from patient care to post-processing techniques

The Basics of CT
The Basics of CT

The Basics of CT is designed to provide an introduction to CT scan imaging. The course is comprised of 8 modules that cover the major areas of knowledge and practice in CT, including patient care and reducing patient radiation dose, CT scanner evolution, the impact of different factors on image quality and patient dose, key concepts in image acquisition, parameters, as well as post-processing techniques, and much, much more.

As an introductory course, The Basics of CT is appropriate for technologists who need a refresher on the fundamentals of CT scan, for technologists who are cross-training into CT and need to build their knowledge base and competencies, and for students in radiology programs looking to enhance and supplement their knowledge of the modality.
