After each X-ray is completed, the couch on which you are lying moves forward a small distance and another image is taken. And with lots of slices, you can make pictures of the body from different angles and also 3D models. This helps doctors see larger areas of the body and the movement of things like blood flow. Currently, ultrasound imaging requires bulky and specialized equipment available only in hospitals and doctor’s offices. But a new design by MIT engineers might make the technology as wearable and accessible as buying Band-Aids at the pharmacy. The book is based around giving children information about their body and how it works so it only gives one view point. As it is not a book based around opinion but rather about facts. For patients who require long periods of imaging, some hospitals offer probes affixed to robotic arms that can hold a transducer in place without tiring, but the liquid ultrasound gel flows away and dries out over time, interrupting long-term imaging. The elastomer prevents dehydration of hydrogel,” says Chen, an MIT postdoc. “Only when hydrogel is highly hydrated can acoustic waves penetrate effectively and give high-resolution imaging of internal organs.”

A typical scan lasts between 15 and 60 minutes, depending on the size of the area being scanned and how many ‘pictures’ are taken. MRI scans are painless. However, it is important to be as comfortable as possible during a scan, because you must keep the part of your body being scanned very still to avoid blurring the images. But these experimental designs have produced low-resolution images, in part due to their stretch: In moving with the body, transducers shift location relative to each other, distorting the resulting image. providing a guide for further tests or treatments – for example, CT scans can help to determine the location, size and shape of a tumour before having radiotherapy, or allow a doctor to take a needle biopsy (where a small tissue sample is removed using a needle) or drain an abscess An MRI scanner is like a short tunnel that’s open at both ends, through which a motorised bed passes. During a scan you lie on the bed and a small ‘receiving device’ is placed behind, or around, the part of your body being scanned. You are then moved into the scanner tube, either head-first or feet-first, depending on which part of your body is being scanned.

We envision a few patches adhered to different locations on the body, and the patches would communicate with your cellphone, where AI algorithms would analyze the images on demand,” says the study’s senior author, Xuanhe Zhao, professor of mechanical engineering and civil and environmental engineering at MIT. “We believe we’ve opened a new era of wearable imaging: With a few patches on your body, you could see your internal organs.” Because of the magnetic field generated, they’re not a suitable imaging technique for patients who have pacemakers or other pieces of ‘metal’ in their bodies – umm, like Body with his keys! The part of your body that needs to be imaged is then exposed to X-rays for a fraction of a second. The X-rays hit the a negative plate (like an old film camera) or are captured by computers. In recent years, researchers have explored designs for stretchable ultrasound probes that would provide portable, low-profile imaging of internal organs. These designs gave a flexible array of tiny ultrasound transducers, the idea being that such a device would stretch and conform with a patient’s body.

With imaging, we might be able to capture the moment in a workout before overuse, and stop before muscles become sore,” says Chen. “We do not know when that moment might be yet, but now we can provide imaging data that experts can interpret.” Since the text and illustrations are quite detailed and the numerous flaps, this book is best suited for a classroom or home library. The device’s adhesive layer is made from two thin layers of elastomer that encapsulate a middle layer of solid hydrogel, a mostly water-based material that easily transmits sound waves. Unlike traditional ultrasound gels, the MIT team’s hydrogel is elastic and stretchy. It’s a very safe and painless way to get a look inside, which is why it’s used to see babies inside their mummy’s tummies.Wearable ultrasound imaging tool would have huge potential in the future of clinical diagnosis. However, the resolution and imaging duration of existing ultrasound patches is relatively low, and they cannot image deep organs,” says Chonghe Wang, who is an MIT graduate student. Dr Singh says: "So many of us tend to put off seeing our doctors, or simply deny that there’s anything wrong. Confronting our conditions, face-to-face with these incredible 3D images, means there’s nowhere to hide. And that can prompt patients to ask really difficult questions. Armed with more knowledge about their own bodies, I saw patients ask not just about their treatment and recovery, but also about life death and everything in between. The power of this technology is that it allows doctors and patients to talk about the stuff that really matters." You will be asked to lie on a table or stand against a surface so that the part of your body being X-rayed. A radiographer will show you where to position yourself to ensure the best image is taken. A CT Scan – sometimes referred to as CAT scans (but has nothing to do with cats or kittens) – work in the same way as X-rays but using computers to create detailed images of the inside of the body. They’re carried out in hospital by specially trained operators called radiographers and can be done while you’re staying in hospital or during a short visit.

I would recommend that this book is on display in the class we're doing about their body for their science topic. So the children can freely look at the book at one time. Was passiert in deinem Gehirn? Wie funktioniert deine Lunge? Warum schlägt dein Herz? Detailreiche Illustrationen und über 50 Klappen enthüllen faszinierende Fakten über deinen Körper. So erfährst du ganz genau, was sich in deinem Inneren abspielt! Dr Singh says: "The 3D images of the patients’ bodies are incredible. As a doctor, it sometimes feels that language isn’t up to the job of truly explaining what is happening inside the gloriously complex human body. How amazing, then, to have a tool that allows realistic, accurate and personal images to do some of the job for you! When you’re ill, the first step towards recovery is coming to terms with your diagnosis, and I think being able to see, literally, what’s going on inside your own body gives patients the understanding to really do that. But this isn’t just for patients – the truth is, despite all my years of medical training, I’d never seen the human body quite like I did on this show. Being on this show has been a real first for me. I’ve never experienced health in this way, and it’s been an eye-opener." MRI scanners are a bit like the CT machine, but you lie inside a huge magnet. It uses magnets and radio waves to create an image of the body.

Ultrasound don’t use radiation to take images. They use sound waves to make images from the echoes. diagnosing conditions – including damage to bones, injuries to internal organs, problems with blood flow, strokes and cancer However, because it does not use ionising radiation and can create detailed images of soft tissue, it can be used for the detection of many diseases.

Instead of shining the beam through the body in just one direction, the X-ray beam passes in a circle around the body and creates a picture ‘slice’ through the area. The book is written in a mixture of short and compound sentences that are easy for children to read on their own. Mainy on the sentences are accompanied by a picture or diagram so the book is very visual to help children understand the complex language. The text is laid out within the diagram, which again adds to the book being easy to follow.

In general, body scanners are designed to detect non-metallic items on people's bodies that metal detectors may miss, USA TODAY reported. The scanners can't see inside of your body, and you don't appear naked in the scan. If you do set off the scanner, and you don't have anything on your body, you're most likely going to be just fine. "The full-body scanners used in all airports since May 2013 are called 'millimeter wave' machines, which bounce electromagnetic waves off the traveler to provide an animated image where a suspicious item might be located," USA TODAY noted. The child would need to have a basic understanding about the body for example the name of organs or know where they are placed in the body. As this book builds on this knowledge and looks at how the different parts operate and work together to keep a person alive. A child would also need to be able to confidently read on their own therefore the book is aimed towards children reading at the age of 8+. Dr Singh says: "There have been so many, not least the look on all the patients’ faces when they first came face-to-face with their own bodies in larger-than-life technicolor. But in the first episode we meet Hilda, who had one of the worst cases of fibroids her consultant had ever seen. My mouth literally dropped when we were treated to augmented reality image of what it would look like to have all her 90-plus fibroids lined up in a row. But even more astounding was just how different Hilda seemed when I met her after her operation to remove them. The physical transformation alone was mind-boggling, but what brought tears to my eyes was just how much more alive and whole she seemed, too. She was a different woman!" You need to lie very still while each scan is taken to avoid blurring the images. The radiographer will leave the room during the scan but will be able to talk to you through an intercom. Several scans will be carried out and the whole procedure may last from a few minutes to thirty minutes. And sometimes a special dye is put in your body which helps the radiologists see what’s going on.
