Technicians operate sophisticated equipment that includes X-ray, mammography, computerized axial tomography (CAT) and positron emission tomography (PET) scan devices. By guiding patients through each step of their medical imaging procedures, these specialists ensure the production of high quality images. They also play a pivotal role in assuaging the anxieties of patients who may be concerned about the procedure or their condition.
