In a first for surgical procedures, doctors have used Google Cardboard to perform a life-saving operation on a baby.
Miami doctors used the $20 (£14) toy to visualise 3D-images of a patient's heart helping them plan a tricky surgery.
"It was mind-blowing," says Cassidy Lexcen, the baby's mother told CNN.
"To see this little cardboard box and a phone, and to think this is what saved our daughter's life."
Teegan Lexcen, was born in August missing a lung and almost half her heart, which medics had never seen before.
In order to plan the next course of action, cardiology specialist Dr. Redmond Burke, asked for a 3D model of Teegan's heart to be made.
However, on that particular day the hospital's printers were broken leaving the team with few viable options. Enter Google Cardboard.
Burke's colleague a paediatric cardiologist suggested using an app, Sketchfab, to download images of Teegan's heart onto his phone.
Both doctors were then able to view the organ from every angle in relation to the ribcage, using the Cardboard.
