Mobile ultrasound jobs refer to working as an ultrasound technician who travels with sonography equipment and technology to different health care facilities to provide ultrasound imaging services to a patient. As a mobile ultrasound technician or mobile sonographer, your responsibilities include working with other members of a health care team, such as a radiologist who performs x-ray services to properly diagnose patients, traveling to facilities that need your help, and sometimes marketing yourself to new potential clients. Mobile ultrasound jobs require excellent interpersonal skills, a desire to help patients, and familiarity with the technology. You typically work as an employee for a health care company, but some mobile sonographers work on a contract-only basis.
