Movie shows a 12 week fetus in 3d in realtime (hence 4D). The beginning of the movies shows the ventral (anterior) view of the fetus head to top. Arrow indicates: initially head, then upper limbs, then lower limbs, then umbilical cord and finally the placenta. The second part of movie shows fetal movements. Calibration visible on left shows 1 cm increments. (More? Labelled Image)

Image from near end of above movie showing ventral view of fetus head to top, upper limbs, lower limbs and umbilical cord visible. Note the small cranial appearance, the cranial vault relatively under developed at this stage. Compare this with the later 19 week ultrasound images.

UNSW Embryology has many movies to show some of the dynamic changes that occur during embryonic development. These have been grouped together on separate pages (listed in righthand menu) that can be also be opened from a pull down menu on each page.
Special thanks to Dr Andrew McLennan, Foetal Medicine Unit, Royal North Shore Hospital for original video materials.
There are additional 2D, 3D and Multiplanar ultrasound movies available from the listed ultrasound links on this page.
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
