:00:48. > :00:58.Arsenal have a lot of work to do in the second leg match to stop
:00:59. > :01:04.Virtual reality - it's the tech that can transport you to other worlds -
:01:05. > :01:07.and now VR is being used to help kids, needing special
:01:08. > :01:09.hospital scans, to relax. Here's Ricky...
:01:10. > :01:11.10-year-old Matthew is back in hospital.
:01:12. > :01:19.In September 2014, I suffered from extreme hydrocephalus,
:01:20. > :01:24.which means a build-up of fluid on the brain.
:01:25. > :01:35.The op was a success and to help him recover,
:01:36. > :01:41.he has to have regular brain scans to check that all is good.
:01:42. > :01:43.The scanning machine can be quite a scary experience
:01:44. > :01:46.The scanner itself can take up to an hour.
:01:47. > :01:49.You have to stay incredibly still in a small space and once
:01:50. > :01:51.the scanner actually starts, it's incredibly loud.
:01:52. > :01:52.Is everything okay and there, Matthew?
:01:53. > :01:57.Now, I feel okay because I have had it a few times now.
:01:58. > :01:59.The first time I remember, I was thinking to myself,
:02:00. > :02:14.Because no one had showed me it buy in the end,
:02:15. > :02:22.MRIs can help doctors find out if a person has any problems
:02:23. > :02:24.using strong magnets and radio waves producing detailed images
:02:25. > :02:29.Experts at Kings College Hospital have come up with a way to prepare

:02:32. > :02:36.Matthew is one of the kids helping the doctors put
:02:37. > :02:42.This is the MRI scan we are going to use today.
:02:43. > :02:47.The app uses panoramic 360 degree videos, taken inside the scanner,
:02:48. > :02:50.giving the complete MRI experience of the scan.
:02:51. > :02:58.I was really interested in virtual reality.
:02:59. > :03:00.I had a 360 degree camera for Christmas and I thought maybe
:03:01. > :03:07.I can take some images from inside the scanner to allow
:03:08. > :03:10.the child to experience a scan virtual reality beforehand
:03:11. > :03:13.to prepare them for the scan, so it is not so scary
:03:14. > :03:19.The best way to cope with it, I think, is to close your eyes.
:03:20. > :03:24.Hopefully, this app will really help and just don't worry about it.

:03:55. > :04:01.work. He's a great author. I'm interested see what he does. When I
:04:02. > :04:06.first read the book, to this day, there are things that stand out. I'd
:04:07. > :04:10.like to meet the characters again. To see where they are now in how
:04:11. > :04:17.their lives have developed. And maybe bring Sunni characters in. I
:04:18. > :04:26.would quite like him to do something completely separate from the dark
:04:27. > :04:27.materials. His dark Materials research cookbooks. These are the
:04:28. > :04:32.ones will hopefully be good as well. From talk of mythical
:04:33. > :04:33.creatures to real-life ones, These four rare otter
