Diagnostic Medical Sonography

Associate in Science

The Associate degree program in Diagnostic Medical Sonography (DMS) prepares students for employment as entry-level sonographers in hospitals, outpatient clinics, and medical offices. The program provides individuals with the academic and technical skills necessary to perform abdominal-extended, obstetrical and gynecological, and vascular sonography procedures. Students are eligible 60 days prior to graduation to apply and take their examinations through the American Registry of Diagnostic Medical Sonographers (ARDMS). Upon completion of the program, students are also eligible to apply to take the national registry examination from the American Registry of Radiologic Technologists (ARRT) The program requires 24 months of full-time study.

  • Students will demonstrate professional and respectful behavior in all interactions.

2. Students will demonstrate skills in critical thinking and problem solving principles and practices of sonography.

  • Students will evaluate and assess patient requisition in order to perform proper sonographic procedures
  • Students will examine the sonographic and Doppler appearances of iatrogenic, degenerative, inflammatory, traumatic, neoplastic, infectious, obstructive, congenital, metabolic, and immunologic disease practices
  • Students will analyze the relationships between various disease processes and hemodynamic states
  • Students will explore the various imaging and testing modalities
  • Students will examine the effects of pharmacology on disease processes and on sonographic findings.

3. Students will demonstrate clinical competence in the practice of sonography.

  • Students will demonstrate exceptional patient care skills
  • Students will provide a safe environment for patients
