About this Program

In the past several years, significant advances in the technology of Computed Tomography (CT) have driven an expansion in the clinical applications and an increase in the number of CT scans performed. Opportunities for CT technologists have grown, however most technologists lack the training necessary to understand the scope and breath of radiation risks in our current CT environments and their role in controlling radiation exposure to their patients. The competent CT technologist must have the most current information in order to provide quality patient care.
