CT technicians use computed tomography to obtain radiographic images. Educational prerequisites and state licensure are required in the US, and specialization requires additional study and certification. CT technologists administer intravenous contrast medication and are accredited by national organizations.
A computed tomography technician is a healthcare professional trained in the use of computed tomography (CT) to obtain radiographic images. Increasingly, CT scans are used as a valuable diagnostic tool in place of standard X-rays because of the clarity and multiple viewing possibilities of the images they provide. Radiographic or X-ray technicians are entry-level positions for radiologists with the least amount of educational preparation. Despite this designation, there are still significant achievements to be made in order to become a CT technician and work in the field. In the US, educational prerequisites and state licensure are required for this position.
Completing a high school diploma or a general educational development (GED) exam is the first step in becoming a CT technician. Most students study to become a radiology technician through a professional training program, a hospital-related program, or a community college. While classes can still be taken for a simple certification as a radiographic technician, most career entrants now earn at least an associate’s degree in radiology to make themselves more competitive as a job seeker. More general certification as a radiographic technician is required before the specialization and study required to become a CT technician. CT radiographic specialization also increases graduate opportunities in the job market.
After successfully completing the classes required for certification or the associate degree, there are still other requirements to complete to become a CT technician. All US states require licensing by successful exams or additional processes. Also, most employers require radiology technicians and technologists to be certified in their field in order to protect patients from overexposure to radiation. Certifications and licenses renew every two years, and most states require completion of continuing education (CE) to keep up with advancements.
In fact, there are fewer CT technicians than CT technicians. This is because a CT technician’s foray into specialization often requires additional study, education, and certification that advance the healthcare professional from a technician to a technologist. CT technicians and technicians are responsible for positioning patients on the CT scan machine and operating the computer system to properly visualize the area under study. Technologists, however, also administer intravenous contrast medication as requested by the supervising radiologist. In the US, two national organizations—the American Registry of Radiologic Technologists (ARRT®) and the American Society of Radiologic Technologists (ASRT)—offer testing, accreditation, and membership to CT technologists.
