Radiologic Technologist

Radiologic technologists perform diagnostic imaging examinations and perform radiation therapy treatments. Radiologic technologists who perform medical imaging examinations work closely with radiologists and are responsible for accurately positioning patients and ensuring that a quality diagnostic image is produced. Radiologic technologists work directly with patients and are responsible for explaining procedures, positioning patients on the examining table and adjusting immobilization devices to obtain optimum views of specific body areas. The technologist moves the imaging equipment into position and adjusts equipment controls based on his or her knowledge of the procedure.
The technologist also is responsible for using radiation safety techniques to ensure exposures for team members and patients meet ALARA (As Low As Reasonably Achievable) standards. To prevent unnecessary radiation exposure, a technologist uses radiation protective devices like lead aprons and shields. In addition, the technologist sets the appropriate collimation to minimize scatter radiation. Collimation is the process of adjusting the x-ray beam to the anatomic area appropriate for the procedure.
The technologist also may operate mobile x-ray or ultrasound equipment to obtain images in the emergency room, operating room or at the patient's bedside. Technologists also assist radiologists with general radiology, computed tomography, magnetic resonance imaging and ultrasound procedures.
Radiologic technologists also work on the radiation oncology team. Radiation therapists administer targeted doses of radiation to the patient’s body to treat cancer or other diseases. Radiation therapists are highly skilled medical specialists educated in physics, radiation safety, patient anatomy and patient care.
Registered radiologic technologists must complete at least two years of formal education in an accredited hospital-based program or a two- or four-year educational program at an academic institution and must pass a national certification examination. With additional education and training, a technologist can specialize in a particular diagnostic imaging area. Radiologic technologists are certified by the American Registry of Radiologic Technologists. To remain registered, technologists must complete continuing education credits.
