Ultrasound Technician Schools Long Island

To become an ultrasonographer, you will need to get your associate’s or bachelor’s degree from a trade school, community college, or university. Ultrasound degrees usually take about two years, but there are accelerated study programs available. Classes will include biology, anatomy, and other medical topics as well as hands-on experience with ultrasound machines. Many sonographers take the voluntary certification exam with the American Registry of Diagnostic Medical Sonographers as an extra mark of confidence for their patients and medical coworkers. In fact, some employers require their sonography techs to have ARDMS certification.
