About The Burwin Institute
Established 1984

The Burwin Institute was established in 1984 to provide quality correspondence courses in diagnostic ultrasound applications. Burwin courses provide a means for technologists to learn theory in a structured fashion needed to challenge the Registry examinations. It is recognized that various institutions offer short courses and seminars for Registry preparation but many technologists do not have the time or finances to attend these types of programs. Studying by correspondence is a proven and effective method of learning.

Burwin courses are comprehensive and current. As such, they are an excellent way of obtaining continuing education points for Registry maintenance.

All our courses are evaluated by the Society of Diagnostic Medical Sonographers (SDMS) and accepted for educational credits or units by the American Registry of Diagnostic Medical Sonographers (ARDMS), American Society of Radiological Technologists (ASRT), Cardiovascular Credentialing International (CCI), Sonography Canada, Society of Vascular Ultrasound (SVU), State of Florida Radiologic Technologists, and state of California Board of Registered Nurses.

Burwin's Authors & Instructors

Chris Harrington - RT(NM), RDMS, RDCS, RVT

Hello! It would be my pleasure to provide some help and instruction through these correspondence courses.

I have been teaching ultrasound both clinically and in the classroom since 1990.

I am presently employed as the Program Coordinator for the Diagnostic Medical Sonography program at Red River College of Applied Arts, Science and Technology in Winnipeg, Manitoba, Canada. I am the author and instructor for the Burwin Institute Sonography Principles and Instrumentation course.

I truly enjoy my job, especially the challenge of teaching Physics and Instrumentation. The mere mention of the word "physics" causes many students to panic. But I believe physics can be fun, understandable, and most importantly, relevant to daily clinical practice. If you can approach physics with an open mind, I know you will surprise yourself.

Denis Gratton - RT(R), RDMS, RDCS

Hello. My name is Denis Gratton. I am the course author and instructor for several Burwin courses including Gynecological and Obstetrical Ultrasound, Ultrasonography of the Abdomen and Small Parts - Part 2. In addition, I coauthor two modules in Introduction to Ultrasound. I enjoy organizing and maintaining my correspondence courses and hope they will be enjoyable and helpful for your learning needs.

My educational experiences as a teacher over the past four decades includes clinical and didactic instruction, conference and seminar lecturing, authoring several chapters in ultrasound texts, and program coordinator for two sonographer training programs. I have always been proud of being a sonographer and part of the diagnostic team.

Professionally, I have participated on the board and committees of different organizations including the American Registry of Diagnostic Medical Sonographers (ARDMS), Society of Diagnostic Medical Sonography (SDMS), Sonography Canada (SC), and the Canadian Medical Association (CMA).

Margaret Corbett - RT(R), RDMS, RDCS, RVT, RMSKS

Hello. My name is Margaret Corbett and I am the author and course instructor for the Burwin Institute correspondence courses in Pediatric and Adult Echocardiography. My courses are primarily intended to cover the material required to pass the credentialing examinations in these respective areas.

I have worked in ultrasound since 1983 and hold ARDMS registration in Adult and Pediatric Echocardiography as well as Abdomen, Ob/Gyn, Ophthalmology, Vascular Technology, and Musculoskeletal Sonography. I am presently employed full time as Supervisor and Clinical Instructor in a busy private practice. My teaching experience began in 1979 in Radiography.

My introduction to teaching through correspondence was through a series of courses in Quality Control which I wrote for the Canadian Association of Medical Radiation Technologists. Throughout the year, I present registry preparation seminars in adult echocardiography in various cities in the United States and have also taught courses in echocardiography at a local community college. I have been with the Burwin Institute since 1992.

Marie Hadfield - RN, RDMS, RDCS

Hello. My name is Marie Hadfield and I am the author and course instructor for the Burwin Institute correspondence course in Fetal Echocardiography.

I started my nursing career working on the high-risk labor and delivery unit at Health Sciences Centre in Winnipeg, Manitoba. I have worked as a nurse sonographer in Fetal Assessment at Women’s Hospital since 1997.

My areas of interest include fetal echo, Rh disease, fetal intervention, Doppler evaluation of growth restriction and monochorionic twin pregnancy.

I enjoy my job very much, particularly the challenge of providing expert family centered care to families whose pregnancy is high risk. I enjoy teaching and have presented both nationally and internationally.

Merle McCann - BA, RT(R), ACR, RDMS, RDCS

Hello. Welcome to the Burwin Institute! I am the course author and teacher for the Burwin Neurosonography, Ultrasonography of the Abdomen and Small Parts - Part 1, and Breast Ultrasound courses. I am also a coauthor of the Introduction to Ultrasound course.

My teaching career began in Radiography in 1973 and expanded into Ultrasound in 1984. I have taught my specialty areas to full-time college students, to graduate students preparing for their Registry examinations and to sonographers and physicians who wished to upgrade their knowledge in these areas.

I sincerely hope upon completion of these courses you will have a similar experience to Kathy T. from PA who wrote : "I wanted to thank you so much for the information given to me through your courses which made the examination so much easier. I learned so much more than I had ever hoped to, and, although some areas were difficult for me to comprehend, I am a much better sonographer today . . . I will be forever grateful that I found out about your courses . . . I felt so well prepared for the examination, and, my grade (87.5%) reflected my knowledge."

Stuart Gibbs - BSc, FCSDMS, RDMS, RDCS, RVT, RT(R)

I qualified in 1987 and still find my work interesting, exciting, and challenging. Currently I am the Supervisor of Ultrasound at The Abbotsford Regional Hospital and Cancer Center in British Columbia, Canada.

My interest in ultrasound has extended to serving in professional societies as a board member of The Canadian Society of Diagnostic Medical Sonographers, (now Sonography Canada), and president of The British Columbia Ultrasonographers Society. I am a Fellow of Sonography Canada.

Teaching ultrasound continues to be a rewarding experience for me whether it is presenting at national conferences, provincial society meetings or teaching students in my department. My areas of expertise include Vascular Technology, Echocardiography, Neurosonography, Musculoskeletal Ultrasound, Abdomen, Obstetrics, and Gynecology.

I am sure you will enjoy the Vascular Technology course.
