HISTORY
Almost 100 years, ago, Sister M. Beatrice Merrigan took 10 required radiographic films (spanning sinus to knee), answered 20 essay questions, and submitted them to the Registry—known today as ARRT. A few weeks later, she received her exam results and became our first Registered Technologist.
In November 2022, ARRT was honored to mark a century of recognizing qualified people who work in medical imaging, interventional procedures, and radiation therapy. Today we certify and register nearly 360,000 technologists in 15 disciplines.
