Sonographers operate the equipment, which collects reflected echoes and forms an image that may be videotaped, transmitted, or photographed for interpretation and diagnosis by a physician.
More than half of all sonographers were employed by hospitals, and most of the rest were employed by offices of physicians, medical and diagnostic laboratories, and mobile imaging services. Sonographers typically work in health care facilities that are clean. They usually work at diagnostic imaging machines in darkened rooms, but also may perform procedures at patients’ bedsides.
Some sonographers work as contract employees and may travel to several health care facilities in an area. Similarly, some sonographers work with mobile imaging service providers and travel to patients and use mobile diagnostic imaging equipment to provide service in areas that otherwise do not have the access to such services.
Most full-time sonographers work about 40 hours a week. Hospital-based sonographers may have evening and weekend hours and times when they are on call and must be ready to report to work on short notice.
