About this deal

Digital photography continues to play a role in medicine through documentation, research and education. Video cameras are commonly used to look inside the body, most often in the form of endoscopes. Scanning technologies collect readings from the body and use a computer to process the data into visual images. The readings can be taken from a variety of sources: J Bronzino, V Smith and M Wade (eds), Medical technology and society: an interdisciplinary perspective (Massachusetts: MIT press 1990)

Ultrasound scanners typically consist of a hand-held device called a transducer to scan the body and a computer with a viewing screen to display the processed data as an image. Crystals in the transducer send high-frequency sound waves into the body and it detects the returning echoes. This is called the piezoelectric effect and was discovered by Pierre Curie (1859–1906) in 1880. A CT (or CAT) scanner works by sending multiple X‑ray beams through the body at different angles. This is called tomography. Detectors record how the beams pass through sections of the body and the data is processed by a computer into cross-sectional images or virtual ‘slices’.

X-rays were the first technology that made it possible to see inside the body without having to open it up. They were discovered by German physicist Wilhelm Roentgen (1845–1923) at the end of the 1800s and had an immediate impact on anatomical study and diagnostics.

B Holtzmann-Kevles, Naked to the Bone: Medical Imaging in the Twentieth Century (New Jersey: Rutgers University Press, 1997) Look Inside Your Body is one of the best Usborne books, and a book absolutely every family should own. It breaks down the body systems and functions in a way that’s easy for young kids to understand.In 1971, American scientist Raymond Damadian (1936–) discovered that MRI could be used for medical diagnosis. The radio signals emitted by cancer cells in a tumour were different from those in healthy cells and could be isolated by the MRI scanner. Damadian built the first whole-body MRI scanner in 1977, which he called the 'Indomitable'.

Learn more about your body in this lift-the-flap Look Inside Your Body Usborne book. Flaps are layered under flaps to dive deeper into the body layers.

An MRI scanner detects these weak signals. Because each of the body’s tissue types emits a different frequency of radio waves, the MRI scanner can distinguish between them and build an image based on the data it receives. When a body is placed between an X-ray source and a photographic (or fluoroscopic) film or screen, an image forms. Denser body parts, such as bones, absorb more X-rays, creating lighter areas on the image. Softer tissue allows X-rays to pass through, leaving dark shadows on the image. The book is all about the human body from the digestive system to the skeleton and everything in between. There is a lot of detail but not too much that makes it difficult for the children to read.
