One area of medicine which has a lot of demand and could potentially benefit from miniaturisation is medical imaging. In the uk, over 41 million scans take place every year in the nhs using x rays, mri and ultrasound. In an emergency, at the bedside or even in an ambulance, it can be complicated to get a patient to one of these large machines. But now, portable medical devices made in the uk could change our lives, giving doctors and patients instant access to ultrasound at a reduced cost. The intensive care unit of southampton Childrens Hospital admits hundreds of patients each year with a range of medical conditions, from Heart Disease to trauma and neurological emergencies. Effie was admitted with a lung infection and needs constant monitoring with tests, x rays and ultrasounds. Usually these are performed by expert radiologists and they arent always immediately available. This ward has four point of care ultrasound machines. These two cost over £50,000 each. But now the same test can be carried out using a Smartphone App and probe, which fit into a doctors pocket and cost a fraction of the price. She had heart surgery yesterday for a condition which is a problem in the heart where there are four different issues. One of the complications of that is sometimes fluid around the lungs. So it southampton routinely do an ultrasound scan of childrens so at southampton routinely do an ultrasound scan of childrens chests before taking out chest drains and to make sure that all the fluids gone. This ultrasound system is called the butterfly, and consists of a hand held probe which attaches to an i0s smartphone or tablet. This is now filming where the lung meets the diaphragm. Well, that lung looks completely normal. There is no fluid around the lung, there is no fluid in the lung, the lung is moving well. It costs only £1699 a fraction of the cost of the larger machines. And its small footprint means its less invasive at a childs bedside. One of the problems with most ultrasound machines is that theyre designed with adults in mind. And so all of the presets are designed for adults. What weve actually got here is a whole variety of paediatric settings as well. So i can select paediatric lung, paediatric heart, paediatric abdomen, but i could also flip and standard adult lung, it nowjump between one probe with the press of a button rather than changing the probes in that ultrasound machine over and over to get the right probe. Lets get rid of all this jelly. Well done. Traditional ultrasound machines use piezoelectric crystals, individuals crystals are cut into different shapes and sizes as different frequencies are used to image different parts of the body. But this also means that different probes are needed. The butterfly uses ultrasound on a computer chip and needs only one probe for different body parts. We are the worlds first ultrasound on chip, a single probe whole body imaging system, instead of the typical 124 imaging elements that are in a pzt probe, there are almost 9,000 elements in this. And so we can recreate all the different types of probes with just one. And that becomes really important as you scan different areas of the body in an emergency, you dont have to keep shifting probes. Just a simple change within the application itself you can go from heart and lungs very quickly and make rapid decisions on whats actually wrong with the patient. The information from the app can be anonymously sent to a secure server for different doctors to review quickly. The implications for Global Health for a portable and relatively cheap solution for scanning are clear. An estimated 5 billion people around the world dont have access to medical imaging of any kind. In sub saharan africa, the device is being used to check for pneumonia, the leading infectious cause of death in children under five. In fact, the companys chief medical officer made his own alarming discovery when scanning himself during the devices testing. When we were doing the studies for fda clearance, i noticed some fullness in my neck, i put the probe up to my neck and looked at my phone and i shockingly saw a very large mass which ultimately turned out to be a metastatic cancer. Yeah. So im patient number one of the butterfly and living proof that having an immediate access to an image can change your health and your life. Southampton has bought four of the devices and plan to always have one available in its childrens ambulance. When you are in front of a child that is critically unwell and you desperately need information, and you are relying on a third person, and youre watching a child deteriorate and you feel powerless. Actually, this gives you the power. This gives you the information to look inside to keep the kids chest. It gives information to look at their heart. You can decide for yourself within seconds. And suddenly, looking after Sick Children is a bit less scary. For now, the butterfly is only available to medical professionals. But tests are currently underway with a group of cardiac patients scanning themselves at home. The Artificial Intelligence built into the device will help guide the patient of the right area to scan, and perhaps with regulatory approval, one day, at home ultrasound scans could be a reality. Tate modern in london opens a major show of the work of the korean visionary nam june paik, which brings over together 200 of his pieces. Here is someone who made a career of being ahead of his time. He was the ultimate early adopter. He came up with the idea of wearable tech, codeveloped the first video synthesiser in 1970. He coined the term electronic superhighway in 1976. And, he vjed a live global videocast via satellite in 197a. Although paik was korean, he spent an awful lot of time injapan. And a lot of his work is influenced by japanese culture. I mean, no one loves a robot more than the japanese, am i right . And in fact, japan is where we are heading now for its annual tech extravaganza ceatec. Dan simmons and emily bates are waiting for us on the show floor. Modulated hello, and welcome back to ceatec. This is ridiculous. Some things that japans annual tech shindig can leave visitors speeches, unfortunately, not so for emily. I have no idea what im doing. Laughs. Now, over to the kitchen, is your robot dog trying to tell you something . Sonys aibo is now faithful to hitachis appliances. If you leave the fridge door open or the washing machine finishes its cycle, he will come over and find you and bark and wag his tail because an alarm going off isnt as cute and wont sell products. He even rides the robot cleaner, just like real dogs. And with these transparent tv screens from sharp, shop windows may never be the same again. Ok, this is something im personally quite interested in and excited about. And part of the reason for that is any sample they take, if they do, takes a few hours or maybe even a couple of days to tell us what weve got. Murata at 0saka prefecture university have created a portable device that gathers bacteria, making it quicker and easier to analyse. A laser is pointed underneath the sample that is on a substrate, basically a plate that is based on this device, and we can see here what the microscope is seeing. Now, look closely and you will see the movement of the water that surrounds the sample. The movement of water is causing a concentration of the bacteria, or indeed the virus, down towards the bottom towards that plate. So theres no need to grow anything. Sony devoted its entire stand to health tech this year. Including this cell analyser that tracks biomarkers which can help detect cancer and uses lasers that may be familiar to you. We are actually using the blu ray players technology. We are detecting the cancer by laser and then detecting the scattered light from the cells. That is exactly the same as blu ray players. Dan, what on earth is going on over here . Just trying a little bit of surgery. Surgery . Mmm. Are you a brain surgeon now . With these 3d glasses and a 3d screen there, this is one of the best resolutions for any surgery. This is actually used, this camera here is actually used in surgeries. And the trick is not to look down at what you are doing inside this brain, for example, it is to keep looking up at the screen and still youve got the peas that you want. Very good and then, look at how small that is that is absolutely tiny. Look at this. That is so small. Im no brain surgeon, emily, i can tell you. Im busted. But this is childs play. And finally, dan found a visible way to converse with the locals here they didnt involve flapping his arms around. Konichiwa, hajimemashite. I have no idea what that means, but with a swipe of the finger, theres the japanese. And theres the english. Hello, nice to meet you. That is it for the short version apart from the big announcement and thatis apart from the big announcement and that is that tickets for the live show are now available. This year were coming to dundee scotland and were coming to dundee scotland and we would love to see you there. If you would like to see us in the flesh, go to our website and apply for tickets. Cannot wait thank you for tickets. Cannot wait thank you for watching and we will see you soon. Hello and welcome to newswatch with me, samira ahmed. A week of excitement for correspondents in westminster and brussels, but has bbc news done enough to explain what exactly the new deal is . And has coverage of a royal trip to pakistan focused too much on what the duchess of cambridge was wearing and harked back too much to the dukes mother, Princess Diana . The frenzy of speculation and anticipation over borisjohnsons deal with the European Union finally came to an end this week, only to be replaced by the new uncertainty of whether that deal will get through parliament. Heres assistant Political Editor norman smith talking to Victoria Derbyshire just after the breakthrough had been announced on thursday morning. We are heading for one humongous showdown on saturday. 0k, stay with us, because imjust getting this from the dup. They say, our earlier statement still stands in response to news that a deal has been reached. 0h 0k. So, were in the strong arm territory, then. But, amid all the excitement among political journalists, some viewers felt there wasnt enough basic explanation of what exactly had been agreed to. Heres what one caller, steve, had to say. Every bit of talk is about northern ireland. I would really love to know what the rest of the deal actually involves, how the relationship with europe will be after this deal has been concluded. It would be really nice notjust to constantly hear about dup and irish backstop. What is the deal . Be lovely to know. 0k, just some feedback. Thank you. Well, bbc news has certainly made attempts since then to explain exactly what is in the agreement particularly online but the detail may have been drowned out by the rhetoric of those applauding or decrying the deal. And there was some literal drowning out on wednesday, when the news channel was again broadcasting live from College Green outside the houses of parliament. Replacing eu systems. Shouting drowns out speech. So that remains to be seen how well that works. Well, regular newswatch viewers will have known that was coming, and that such noises oft annoy many members of the audience. And it was no exception here, with mike burgess reacting like this. The distractions arentjust verbal, of course, but visual, too. The holder of this leave, then negotiate placard managed to get in shot several times as a bbc camera pursued interviewees down the street. And while that perhaps was unavoidable, some argue
