Is 3D/4D Ultrasound imaging safe? What is the difference between 3D and 4D?

Ultrasound has been used for over 30 years in obstetrics with millions of images produced. Numerous studies and medical research has shown no known adverse side effects when used properly. There is no increase in sound waves used in 3D/4D imaging over 2D imaging (commonly used at OBGYN offices), only an increase in the action of the transducer and software reading and interpreting the data. Our machine is a new, well maintained Medison 8000 SonoAce set with the OB Application in place and with energy limits set by the manufacturer below FDA limits. There is no radiation involved when using sonography. 3D images are the still images we take and save on the photo disc and 4D (also known as 3D Live) are the moving images recorded on the DVD.  more
