i went for the 3d scan at mount e and it cost me $480.
I got back all the soft copies of the scan and 2 colour scans. Actually the colour scan is just in brown, black, grey and white, doesn't really come in 4c!
the gynae told me that 4d scan just means that the 3 d scans are being made into a 4 dimensional video but i dont't know how true that is. I've heard of parents who can actually see their bbs yawning or sucking their thumbs!
from the 3d scan, i could see that my dear daughter's thick lips came from her father!
