Computed Tomography (CT)


CT can be an exciting and fulfilling career. As a CT technologist, you’ll likely work in a hospital or an imaging center. You’ll perform scans on all parts of the body for a variety of reasons. Some patients need imaging to diagnose a disease or an acute condition. Others need CT scans in emergencies, so physicians can understand the extent of injuries. While you perform the procedures, your skills and confidence will be critical as you balance image quality with radiation dose. You’ll also help inform and calm nervous patients.

The purpose of ARRT certification and registration in CT is to recognize individuals who are qualified to perform the role of a computed tomographer. To earn ARRT certification and registration in this discipline, you'll use our postprimary eligibility pathway. This requires, among other things, that you already hold ARRT credentials in an approved supporting discipline. In some cases, you may earn your supporting credential through another organization.  Learn more about eligibility requirements and view additional resources below.
