Diagnostic Medical Sonographer

💰High PayQuick Start👤Patient Care📋Support & Admin

A Diagnostic Medical Sonographer—also called an Ultrasound Technician or Sonography Tech—is a specialized healthcare professional who uses sophisticated ultrasound equipment to create real-time images of the body's internal organs, tissues, and blood flow. Using high-frequency sound waves rather than radiation, you'll produce sonograms that physicians rely on to diagnose conditions ranging from tumors to monitoring fetal development. This makes sonography one of the safest imaging modalities available.
