How to Become a Diagnostic Medical Sonographer (Ultrasound Tech)

Interested in healthcare imaging? Diagnostic Medical Sonographers—also known as Ultrasound Technicians—use soundwave technology to create detailed images of patients’ internal organs, tissues, and blood flow. This guide explains every step to becoming a certified Sonographer in 2025.

What Does a Diagnostic Medical Sonographer Do?

Ultrasound Technicians use specialized imaging equipment to help physicians diagnose medical conditions and monitor pregnancies. They interpret soundwave reflections to produce high-resolution diagnostic images.

Common duties include:

• Preparing patients for imaging procedures
• Operating ultrasound and Doppler equipment
• Capturing and evaluating diagnostic images
• Communicating findings to physicians
• Maintaining patient records and imaging equipment

Diagnostic Medical Sonographers combine medical knowledge and technical precision to improve patient care every day.

How to Become a Diagnostic Medical Sonographer (5 Steps)

Follow these steps to launch your sonography career:

1. Earn a high school diploma or GED
   Required before enrolling in an accredited sonography program.
