4D Scan is proudly run by Heidi Richter and Isabel Coetzee – two highly skilled and experienced sonographers.

4D Scan was established in 2007 by Heidi Richter and Isabel Coetzee. They are two internationally qualified sonographers with a special interest in Obstetrics (Baby Scans). Isabel worked as a sonographer in the clinical field, and Heidi applied her skills in the corporate world, then they realized that a need for a private Obstetrics Scanning Facility existed. A place where a mom and dad can go to bond with their baby, but at the same time get expert up-to-date information on their pregnancy.

With technology advancing a further need arose – for doctors and midwives to refer their patients to a trusted professional institute, where they can get key results that will enable them to manage their patient’s pregnancy, and make important decisions to ensure the best possible outcome in each case.

Heidi and Isabel found the winning formula when they established a top class facility in various areas. 4D Scan isfamily friendly facility where you can feel at home, ask questions and experience the hidden world of your baby in the womb.


As a mother of two beautiful children, I realised what a magical time in your life your pregnancy is. We are here to assist you on this miraculous, although scary and overwhelming journey. Heidi completed a National Diploma in Radiography. She also completed the following Ultrasound courses:
  • Ultrasound Physics and Instrumentation,
  • Ultrasound in Abdomen and Small Parts,
  • Ultrasound in Obstetrics and Gynaecology, and
  • 3D/4D Ultrasound Course (Kretz Vienna).

Over the past 10 years, Heidi has gained invaluable work experience and has continually been involved in the application of equipment and training of 3D/4D scans. Scanning obstetrics is one of her passions and most of her education is based on this field.

“I keep up to date with attending updated courses and being involved in the
Society of Radiographers. I am dedicated to help parents discover their miracle in the making.
I understand this through a mom’s eyes because of my two unforgettable journeys”
