Just saw this interesting link: http://www.dailymail.co.uk/sciencetech/article-1195703/The-stunning-new-technology-allows-parents-hold-life-size-model-unborn-child.html
It seems a PhD student Jorge Lopes has found a method to create 3D life size plaster models of the fetus as seen on 3D Ultrasound and MRI imaging. The replicas can help the mother identify and bond more intensely with the baby in the womb. Maybe, in the not too distant future, we may see Obstetricians and radiologists prepare plaster models, as easily as thermal print images of the fetus!!
