About Us

4D Scan was established in 2007 by Heidi Richter and Isabel Coetzee. They are two internationally qualified sonographers with special interest in Obstetrics (Baby Scans). Isabel worked as a sonographer in the clinical field and Heidi applied her skills in the corporate world when they realized that a need for a private Obstetric 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 recipe when they established a top class facility in various areas. 4D Scan is a family friendly facility where you can feel at home, ask questions and experience the hidden world of your baby in the womb.

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