How VR is helping kids in hospitals overcome their fears

These are massive tubes which use powerful magnets and radio waves to produce a images of inside the body.

Doctors use these images to find out if a person has any problems in their bones, blood vessels, heart or brain.

Although they aren't dangerous, some people find the scanners quite scary - they are very loud and some people don't like being in very small spaces.
