It seems there’s almost nothing computers can’t simulate these days: Now, a new computer program simulates human birth using 3D virtual reality.

The simulator is the first of its kind to take into account factors such as the shape of the mother’s body, and the shape and position of the baby. It could help doctors and midwives prepare for unusual or dangerous births, according to the researchers in England who developed it.

“You can’t see inside during a live birth. The simulator shows you what’s happening inside,” said Rudy Lapeer, a computer scientist at the University of East Anglia, leader of the research that was presented Nov. 22 at a conference on E-Health and Bioengineering in Romania.

 Hospitals have used models to simulate the birthing process since the 1800s, Lapeer told LiveScience. But whereas most current simulators are based on known scenarios, the new simulator models the physics of childbirth — the basic forces exerted by the cervix, abdominal muscles and the doctor or midwife — so it can simulate an unfamiliar birth scenario.

The simulator is also designed to be patient-specific. Doctors can scan a pregnant woman, and then adapt the simulator to her anatomy. They can run through a number of scenarios based on previous births.
