4d imaging is a different type of ultrasound. it's very cool, 3d is images, 4d is usually video.

When they do an ultrasound, they can see how and where the babies are positioned, if they share one sack, and often one placenta, then for sure they're identical. Fraternal twins have two seperate sacks and placentas.
