Sonographers typically work in healthcare facilities that are clean. They usually work at diagnostic imaging machines in darkened rooms, but they also may perform procedures at patients' bedsides. Sonographers may be on their feet for long periods of time and may have to lift or turn disabled patients.
Some sonographers work as contract employees and may travel to several healthcare 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 would not have access to such services.
Most full-time sonographers work about 40 hours a week. Some sonographers work overtime. Also, sonographers may have evening and weekend hours when they are on call and must be ready to report to work on short notice.
p/s: This is the work environment for the sonographers in US or UK.It is quite different here in Malaysia. We don't travel except for those who do locums and part time as an application specialist.
