What is an ultrasound scan?

An ultrasound scan uses high frequency sound waves, which are inaudible to the human ear. These high frequency sound waves are known as ultrasound. This sound is bounced back off Internal organs. The returning sound is picked up and electronically converted to create an image. This enables us to examine the organs and other structures of the child.

An ultrasound scan can be taken in two ways. Externally, via the abdomen or internally via the vagina. We prefer taking an internal ultrasound scan for scans before 10 weeks. We can also still decide at a later period in the pregnancy to take an internal scan in the event of poor image quality with an external ultrasound scan.
