Radiology and imaging technology is a 3 year undergraduate course that produces clear and accurate images of the body that enable physicians to diagnose and treat medical conditions. Technicians operate sophisticated equipment that include X-ray, CT scan, MRI and mammography. By guiding patients through each step of their medical imaging procedures, these specialists ensure the production of high quality images.

Technicians prepare patients by explaining each step of the medical imaging process. After instructing the patients to remove jewelry, clothing or other items that could interfere with the equipment, they position them correctly and protect them from overexposure, for example by covering parts of the body not being filmed with lead aprons. Occasionally they inject barium- and iodine-based contrast agents to improve image quality. A radiology technician may also be responsible for updating patient records and maintaining the imaging equipment itself.
