This 16-month program is designed for students who have completed an AMA Allied Health associate degree or a bachelor’s program with a science or health major. Students obtain the knowledge and clinical skills to function as a diagnostic medical sonographer.

Graduates provide exceptional patient care while using sophisticated ultrasound instrumentation to perform medical imaging procedures. The images assist physicians in diagnosing medical conditions.

NHTI’s intensive program requires four semesters of full-time study of ultrasound specialties such as abdomen, small parts, obstetrics, and gynecology, plus an introduction to vascular sonography. Our small class and lab sizes provide extensive, supervised, hands-on practice. Our faculty assigns clinical sites, providing a well-rounded clinical experience. This program is financial aid-eligible.
