Giving birth inside a noisy machine that makes most people feel claustrophobic isn't something many women would agree to.
But for one mum, it sounded like a chance to do something good for the medical community.
In December 2010, researchers from the Charité University Hospital in Berlin used a magnetic resonance imaging (MRI) machine to record a woman giving birth.
Before the labouring woman entered the machine she was already fully dilated and had had an epidural, and the baby's head was low in her pelvis.
The machine then took images of the second stage of labour, as the baby moved along the birth canal. The machine was turned off before the child fully emerged to make sure the MRI noise didn't impact the baby's hearing.

Christian Bamberg, research team leader, said the study would help doctors better manage labour.
It follows a 1999 MRI video of a couple having sex, which was part of a study looking into the female orgasm and the male and female genitals during intercourse.
