A new 3D ultrasound scan has produced vivid pictures of a 12 week-old unborn baby "walking", yawning and rubbing its eyes in the womb, reported the BBC.
The new scan can provide much greater detail than the conventional ultrasound, which only produces 2D images.
The 3D scan, which records fetal movement in real time, was developed by Professor Stuart Campbell at London's Create Health Clinic.
Campbell has previously released images of unborn babies, including those babies appearing to smile, in a book called “Watch Me Grow”.
