Medical Imaging, Diagnostic Medical Sonography, Associate of Applied Science


Medical imaging technology consists of three Associate of Applied Science (AAS) degrees and four certificate programs.

The degree programs include:

  • medical radiography,
  • diagnostic medical sonography, and
  • invasive cardiovascular technology.

The advanced or enhanced certificate programs are:

  • computed tomography,
  • invasive cardiovascular technology,
  • magnetic resonance imaging, and
  • mammography.

Students selected for any of the medical imaging programs are required to submit a physical exam prior to admission. This physical exam must be consistent with the requirements of the teaching hospitals and agencies the student is assigned during clinical assignments and the performance standards required to function as a student imaging technologist. The exam will also include documentation of any communicable diseases along with immunity to Rubella, Measles, Mumps, Varicella, and Hepatitis B. Additionally, completion of an updated Tetanus vaccine, an annual TB screening, and a seasonal flu vaccine are required.

In addition to meeting all other requirements, a criminal background check and drug and alcohol screening are required for all health science students attending imaging courses, and are required prior to admission to the program. Students entering a medical imaging program will also be required to show proof of health insurance and current CPR (American Heart Associate--Health Care Provider) certification. Students may contact the medical imaging department for details regarding the criminal background check and drug screening requirements.

Associate of Applied Science Degree

A Diagnostic Medical Sonographer is a person qualified to provide patient imaging using ultrasound under the supervision of a medical doctor. The Diagnostic Medical Sonography program prepares students to work in entry-level positions in hospitals and other health care facilities. Upon completion of the Diagnostic Medical program, the student is granted an Associate of Applied Science (AAS) degree and is eligible to apply to take exams for the American Registry of Diagnostic Medical Sonography (ARDMS).

Diagnostic Medical Sonography Program Goals

  1. Graduates will be clinically competent sonographers.
  2. Graduates will be eligible to apply for, take, and pass the American Registry of Diagnostic Medical Sonography certification exams upon completion of the program.
  3. Graduates will be able to find employment.
  4. Graduates will be satisfied with their education.
  5. Employers will be satisfied with program graduates.

The purpose of the Diagnostic Medical Sonography program is to prepare competent entry-level general sonographers in the cognitive (knowledge), psychomotor (skills), and affective (behavior) learning domains. In accordance with fulfilling its purpose, the program will provide experience to support the following: develop proficiency by not settling for a minimum standard; develop independence by showing initiative to complete tasks without being directed to do so; assume responsibility by accepting constructive comments from personnel, physicians, and instructors; solve problems by doing anything, which is reasonable and within one’s sphere of influence, to resolve dilemmas; organize work by arranging tasks so that they are performed accurately and expeditiously; and integrate previous learning by utilizing concepts learned in the past to improve current clinical performance.

Admission Criteria

Students are admitted annually into the Diagnostic Medical Sonography Program. Due to limited clinical internship availability, students are admitted on a competitive basis. In addition to the general admission requirements of San Jacinto College, all prerequisite courses must be completed prior to acceptance into the Diagnostic Medical Sonography Program. Preference will be given to applicants who meet one of the following when applying to the program:

  • Graduate of a two (2) year patient-related allied healthcare program (radiography, respiratory, paramedic, nursing, occupational therapy, or surgical technology);
  • Bachelor’s degree (any major);
  • Licensed Vocational Nurse (LVN) graduate;
  • Certified Nurse Aide (CNA) +2 years work experience; or
  • 3+ years direct patient care work experience.

Computer proficiency is recommended for the Sonography Program. Students who do not have computer proficiency are encouraged to take BCIS 1305 Business Computer Applications or ITSC 1309 Integrated Software Applications I

The applicant must submit a current resume’, official transcripts, and two letters of recommendation. The applicant must complete and submit an application to the Medical Imaging department. Applicants must attend a mandatory information meeting as posted on the San Jacinto College website or by calling 281-476-1871 for dates.  Acceptance into the Sonography Program is determined after review of the application and completion of all requirements.

Upon acceptance in the program, the applicant must also submit required health records, proof of health insurance, CPR (American Heart Associate--Health Care Provider), criminal background check, and drug screen as stated for all Medical Imaging students. 

Prospective applicants should call the Medical Imaging department at 281-476-1871 for additional information.
