X-Ray Technicians operate x-ray machines that take images of the human body through technology that utilizes ionizing radiation. This involves working with both emergency and non-emergency patients, and sometimes with patients who must be x-rayed during surgery. They may also supervise the preparation and positioning of patients who are to be x-rayed, and develop x-ray images for evaluation by doctors. Senior X-Ray Technicians may also supervise and train new staff members.

In addition to the technical knowledge required to operate x-ray equipment, X-Ray Technicians should also have good knowledge of human anatomy. Good communication and interpersonal skills are important for working with patients and other staff members. Hospitals are busy and fast-paced environments, and X-Ray Technicians should therefore be able to work well under pressure.
