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, obstetrical and gynecological, and vascular sonography procedures. Upon completion of the program, students will be eligible to apply to take the national registry examination from the American Registry of Radiologic Technologists (ARRT) and/or the American Registry of Diagnostic Medical Sonographers (ARDMS). The program requires 24 months of full-time study. Students are assigned to clinical practicum at affiliates throughout the state of Connecticut.

Please see the Diagnostic Imaging & Therapy Programs for more information about the admissions process.

Federal Regulation, 34 CFR 668.43-Institutional Information for Disclosure for Licensure Program requires the institution to disclose whether completion of a covered licensure program would be sufficient to meet licensure requirements in a State for that occupation. An institution can make the one or more of the following determinations:


The Diagnostic Medical Sonography (DMS) program at Gateway Community college is accredited by the Commission on Accreditation of Allied Health Education Programs (CAAHEP) 9355-113th St. N #7709, Seminole, FL 3373 and meets the education requirements for a recognized course in the concentration areas of Abdomen, OBGYN and Vascular in the state of Connecticut. In addition, all students of the DMS program who meet the requirements of the program may take the Sonographic Physics and Instrumentation (SPI) credentialing examination during the program offered by the American Registry of Diagnostic Medical Sonography (ARDMS). Additional credential examinations in Abdomen, OBGYN and Vascular may be taken up to 60 days prior to graduation. Students that successfully pass their SPI and one specialty examination will have their ARDMS credentials upon graduation for employment.

 Gateway DMS students are also eligible to take a sonographic national examination through the American Registry of Radiologic Technology upon graduation.

The DMS program at Gateway Community College has not determined if the Associates in Diagnostic Medical Sonography degree meets the state education requirements in any other state, any U.S. Territory, or the District of Columbia. Program applicants should investigate each state requirement for credentials and licensures prior to accepting an offer of admission to the DMS program at Gateway Community College.

Both ARDMS and ARRT credentials are recognized by employers throughout the United States of America. Graduates should check with each state’s labor department for additional licensure information specific to that state.


The agencies in each state are responsible for establishing the requirements for licensure and or credentialing of Diagnostic Medical Sonographers for their state. Students who intend to seek employment in any other state than Connecticut need to consult with the intended state’s professional licensing board for further information.

DMS Program Goals & Student Learning Outcomes

For Abdomen-Extended, OBGYN and Vascular concentrations:

The minimum expectations of the DMS program, as defined by the Commission on Accreditation of Allied Health Education Programs (CAAHEP), are “To prepare competent entry-level Abdominal Extended, Obstetrics and gynecology sonographers and vascular technologists in the cognitive (knowledge), psychomotor (skills), and affective (behavior) learning domains.” The following DMS program goals have been established to realize this mission:

1. Students will demonstrate skills in effective oral and written communication.

  • Students will apply effective verbal communication skills with classmates, instructors, patients, sonographers, and physicians.
  • Students will utilize effective written communication skills with instructors, sonographers, and physicians.
  • 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.

  • Student will demonstrate exceptional patient care skills.
  • Students will provide a safe environment for patients.
  • Students will detect normal anatomy and pathology on sonographic images.
  • Students will adhere to the ALARA principle.
