Sonography has evolved from a simple static black and white image that I couldn't show you the movement of your baby (1975) to the beautiful 2D today.  It evolved to the lovely sepia 3D image I have been showing you your babies in for the past 9 years.  Now I have the second generation 3D image to offer you.  GE refers to it as HD Live.  It is so beautiful.  The detail I'm allowed to demonstrate is extraordinary.
