This page introduces how 3D ultrasound images are generated from a series of images in 3 different planes. The example below shows a 12 week fetal ultrasound images in the sagittal, axial and coronal planes that are used by the computer to generate the final 3D image in the lower right. Computers are able to generate these images in realtime, therefore in addition to static pictures, realtime 4D movies can be generated. (More? 12 week 4D | 19 week 4D) The 3D static image of the 12 week fetus shows a ventral view with the fetus upside down, with the head down and cord to the top. |

Ultrasound images and linked movies on this page represent normal development. Features of abnormal development as detected by ultrasound are listed on a separate page (More? Abnormal Ultrasound )
Special thanks to Dr Andrew McLennan, Foetal Medicine Unit, Royal North Shore Hospital for original video materials.
There also an about movies page which has technical details and terms listed.
Both Mac and PC computers require the Quicktime plug-in to be present in your browser or on your computer.
Internet users note that some of these movies are large and will take some time to download depending on your connection speed.
DVD users can find Quicktime on the DVD or the latest version can be downloaded from here Quicktime
