One of my favourites. See both the little gb flags on the blades, and both the same kind of distance from the water, and i feel like everything just kind of comes together. I mean, Simone Biles is right up there with the greatest athletes of all time. You know, ive photographed her a lot through previous olympics and World Championships and when she is in full flow, she is a sporting perfection, absolutely incredible to photograph as well. Perhaps these games have, you know, were seeing a different side to her. Shes holding the chalk, you know, the chalk for the rest of the team and shes pulling her mask off and looking a bit sad and vulnerable, and i think that picture really tells that story of that day for me. Historically down the years when people look Back On the tokyo games, | that was in the middle of that pandemic and there were no spectators there. I as sport photographers, we want to turn around and say look, you know, the picture that sits in history is something youve ta ken. Beautiful images. Now its time for a look at the weather. Once again, today, weve got big shower clouds on the horizon, downpours, Thunder And Lightning possible too, and on the later Satellite Picture you can see there is a lot of cloud across the uk and only here and there we have lengthy sunny spells. And, actually, lengthy sunny spells possible second half of the day across the South West of the uk. The heavy showers will be mostly across the northern half of the country, and particularly slow moving, for example, in scotland and northern england, so the downpour will last longer because its not being pushed by the stronger winds, which are a little bit further south. So, the showers continue through the course of this evening and overnight, but there will be some clear spells around too for example in the midlands, in wales, not a cold night. And then tomorrow, the showers will be more scattered, so that means therell be more sunny spells developing, and, in fact, for some of us it may end up being a pretty decent day. If you want some drier, brighter weather its looking better on tuesday. Hello this is Bbc News with lukwesa burak. The headlines. After more than two weeks of thrilling Sporting Action the tokyo olympic Games End with a spectacular closing ceremony. Team gb end the games with 22 gold medals. Lauren price took gold in the boxing on the final day, and Cyclist Jason Kennys Gold makes him the countrys most decorated olympian. Gunfire another provincial capital in afghanistan falls to the taliban as they continue to make ferocious assaults against key northern cities. Thousands flee their homes in greece as Forest Fires burn out of control. The country faces its most intense heatwave in more than 30 years. Now its time for this Week Edition of click. This week a special programme. Can Artificial Intelligence make healthcare better for all of us, and save the nhs . Here in the uk the national Health Service has been in crisis for many years, looking after an increasingly ageing population with complex needs. Fighting for resources, it has been at breaking point. And then the pandemic hit. There will come a moment when no Health Service in the world could possibly cope. And indeed, many Countries Health systems have struggled with the sheer number of covid patients. Even those which didnt have people spilling out onto the streets had to put all other treatments on hold. The nhs is an old health system. In fact, its several different systems that sometimes work together and sometimes dont. And now, its trying to reinvent itself and embrace technology to beat the queues that Covid I9 has created. This is a story i started filming just before the first uk lockdown, when we werent yet wise to masks or social distancing, but there was definitely a hint that something was coming. I wanted to find out how Artificial Intelligence could be used to help take up the strain that the nhs was already under. And, on what turned out to be my last day in london for many months, i found myself about to do something that id never done before. I wasnt nervous until i asked my twitter followers what i can expect. Very loud noise claustrophobia. Now im nervous. Im going to have an Mri Scan on my liver. And i have to lay absolutely still . Yep, and theres breathing instructions. This Magnetic Resonance Imaging Scanner Mri Scanner is going to be able to see my soft tissue and my fluid in great detail. And it will produce images like this, which will be looked at by a radiologist to try and work out if they can see anything unusual. Now, the thing produces really strong magnetic fields, which means Nothing Metal can come in and that includes you. But this is no ordinary Mri Scan. Instead of being read by a human, my mri is going to be read by an Artificial Intelligence. This is a computer that will look at the images and read them at least as well as a Human Radiologist would. Breathe out and hold your breath. Now, this film is not about computers stealing jobs. This is a film about computers filling the gaps in an nhs that is short of money, short of nurses, and short of the highly skilled radiologists who can read and interpret images like these. But thats a really difficultjob that takes years of training. I mean, how could you teach a computer to do that . Well, heres a classroom full of medical students, and this is a computer. The way you teach each is very different. What you have in front of you here are Ct Scans of a Human Lung with cancerous tumours. So ill be teaching you how to identify them and hopefully save lives. The Human Brain is brilliant at learning things. It can understand spoken words. It can understand diagrams. Just through the teachers descriptions, these students can have a good guess at Finding Tumours in these images. They get some right, they get some wrong. But with repetition and practice, their brains make more and more connections which strengthen with success until eventually we really understand the task in front of us, and we can do it well. But computers are dumb. They literally know nothing. They Cant Look at a diagram and imagine it in real life. They cant understand spoken words. Normal teaching methods wont work. So, instead of trying to describe to them what we want them to learn, we teach them using trial and error. Millions of trials, in fact. The computer starts by circling completely random parts of the image. Itjust guesses it doesnt even know what its getting at. All it knows is when its guess is right and when its wrong. And mostly, because its guessing, its going to get it wrong. And the great thing about computers is they can do this over and over again, really fast, and they remember everything. And every time it does accidentally get it right, it makes a connection to its previous correct guesses. With every right answer, certain connections get stronger. And with every wrong answer, others get weaker. Through this barrage of guesses a network grows, similar to the Human Brain, which starts to distinguish between right and wrong. A digital Thought Process that we call a neural network. Until eventually, after a multitude of attempts, it has very few failures and a lot of success. Ok, lets try some more difficult scans now. And this is the technique that could soon be helping those suffering with Long Covid. Thanks to Artificial Intelligence, we were able to link Patient Records with imaging and produce an analysis of 41,000 patients, imaging and clinical associations in about two months. Adriana roca is part of a team that has been looking into why Long Covid only affects some people. What we found was quite important and shocking because it was actually not obesity, per se, but fatty Liver Disease linked to obesity that was increasing the risk actually up to five times of being severe with Covid I9. Ajay agade is one of almost A Million people suffering from Long Covid in the uk. He is a0 and a doctor, and he moved to the uk from india to complete his specialist training. So in the last week of march i was on the weekend duties and i was not feeling well. I went back home immediately. I self isolated and then i was tested positive. I wasnt thinking that this virus will affect me because i was a Fit Adult and i thought it would be just ok, like any other Flu Virus is for me. There was a moment when i thought iwilljust die, and i had a three year old, and i would not be able to see her ever in my life. I never knew that this virus will leave me or others with so many problems and disabilities, even after one year. So, to understand his illness more, ajay signed up to a study aiming to help Long Covid patients a trial that is using the very same ai that lured me into that big magnetic tube earlier. This ai had originally taught itself how to spot certain liver characteristics. As well as spotting unusual masses, it had also learned to assess the overall health of the liver. And here is what made of mine. Here weve picked up a small area which isjust a cyst, a simple fluid filled sac. And the ai has picked that up as something unusual, something of interest . Yes, but theres no concerning features to it and we wouldnt survey it. And otherwise its a reassuring scan, with no increased evidence of inflammation, scarring, iron or increased risk of fat. But here is the thing. It turns out that because this ai can assess the overall health of the liver, it can do the same for other organs too. And so we expanded first to organs like the kidneys the pancreas, the spleen and the heart, originally with the aim of looking at type 2 diabetes, but it turned out many of those organs were being affected by covid as well. If it was a radiographer manually analysing data from, say, six different organs that could take up to 24 man hours of work. This allows us to basically automate some of the most labour intensive parts of the process. We are trying to identify. Which kind of fat is the one that puts you at risk. Its not obesity, as weve thought up until now. What makes you at higher risk is the visceral fat, the fat in the organs. Whereas we have found. Also people with low bmi with high fat in the liver. Ajay is part of the Clinical Trial that may show that young fit people with a normal bmi can also get Long Covid if they have fat in their organs. And not everyone is aware about exactly what Long Covid is. I think eventually when the acute things wean off, i think more and more people will come up with Long Covid. There are many trials in the country trying to understand Long Covid, and Artificial Intelligence has become a big tool in the race to find a treatment. But for many, Help Cant come quick enough. Technologies that bring about big change also bring new problems. There is no point in denying that. But right now, ai is changing the World And Opening up possibilities for huge medical breakthroughs. I mean, it helped us to develop highly effective vaccines in record time. So i know the pandemic is far from over, but i still feel kind of lucky that it happened now rather than even just a decade ago. And maybe it will mean the nhs is a bit more ready for the next one
