See Inside Your Body

Product Information

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.

A typical scan lasts between 15 and 60 minutes, depending on the size of the area being scanned and how many ‘pictures’ are 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.

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.

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. 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.”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.

diagnosing conditions – including damage to bones, injuries to internal organs, problems with blood flow, strokes and cancer 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.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. 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. 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. 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.” 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+.

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 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.” 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." 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.

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. 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. 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! 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.
