Computed Tomography (CT) Technologist

Computed tomography (CT) technologists specialize in using ionizing radiation to produce cross-sectional images to help doctors diagnose and treat patients. They work in hospitals, clinics, labs, and outpatient centers.

Computed Tomography (CT) Careers

Technologists working in CT produce cross-sectional imaging using a rotating x ray unit. The images show tissue, bones, organs and blood vessels. ARRT certification and registration is voluntary, but those beginning a career in CT will find that it is required by many healthcare employers.

ARRT doesn't provide a list of job postings within the profession. However, computed tomography (CT) technologists seeking a position may want to check the ASRT JobBank.

Computed Tomography (CT) Certification and Registration

The American Registry of Radiologic Technologists (ARRT) offers computed tomography (CT) certification and registration as part of its mission to recognize qualified individuals in medical imaging, radiation therapy, and interventional procedures. To be eligible for ARRT Computed Tomography (CT) certification and registration, candidates must already hold ARRT certification and registration in radiography, nuclear medicine technology (registration through NMTCB is also accepted), or radiation therapy, meet ethics requirements, document clinical experience, and pass the ARRT certification and registration examination in computed tomography (CT).

Annual renewal of certification and registration is required to maintain the ARRT credential.

Computed Tomography (CT) Continuing Education (CE)

Once certified and registered in computed tomography (CT), Registered Technologists (R.T.s) must complete 24 Category A or A+ continuing education (CE) credits each biennium — a two-year period that begins at the start of his or her birth month.

Technologists already certified and registered in a discipline who become certified and registered in additional disciplines maintain their original CE reporting schedule based upon their initial certification and registration. The continuing education requirement is 24 credits, regardless of the number of ARRT certificates held by a registrant. Technologists who become certified and registered in computed tomography (CT) within a biennium meet the CE requirement for that biennium.

For more information, check out the Continuing Education Requirements.

In addition, any certifications and registrations earned in any category beginning January 1, 2011, are time limited to 10 years, at which time R.T.s will need to demonstrate continued qualifications as part of the Continuing Qualifications Requirements (CQR).
