A CT scan technician is a healthcare professional who has been trained to obtain radiographic images using computerized tomography (CT). Because of the clarity and variety of viewing options provided by CT scans, they are increasingly being used as a valuable diagnostic tool in place of standard X-rays. For radiologists with the least amount of educational preparation, radiographic or X-ray technicians are entry-level positions. Despite this designation, there are still significant accomplishments to be made in order to work as a CT scan technician. In the United States, this position requires both educational prerequisites and state licensure.
The first step toward becoming a CT scan technician is to obtain a high school diploma or pass the general educational development (GED) exam. Most students then enroll in a vocational training program, a hospital-related program, or a community college to study to become a radiology technician. While classes for a simple certification as a radiographic technician are still available, most newcomers to the field now pursue at least an associate’s degree in radiology in order to be more competitive in the job market. Prior to the specialization and study required to become a CT scan technician, a more general certification as a radiographic technician is required. A graduate’s job prospects are also enhanced by a CT radiographic specialization.
After completing the required classes for certification or an associate’s degree, there are a few more requirements to meet before becoming a CT scan technician. In the United States, all states require licensure through examination or other means. In order to protect patients from overexposure to radiation, most employers require radiology technicians and technologists to be certified in their field. Most states require completion of continuing education (CE) to keep up with advances, and certifications and licenses must be renewed every two years.
CT scan technicians are actually in short supply compared to CT scan technologists. Because a CT scan technician’s foray into specialization often necessitates additional study, education, and certification, the healthcare worker is promoted to a technologist. CT scan technicians and technologists are in charge of positioning patients in the CT scanner and operating the computerized system to visualize the area under investigation. However, as directed by the supervising radiologist, technologists also administer intravenous contrast medication. CT scan technologists can be tested, credentialed, and become members of two national organizations in the United States: the American Registry of Radiologic Technologists® (ARRT®) and the American Society of Radiologic Technologists (ASRT).
