Body imaging. Composite image of several methods used to visualise the anatomy of the human body. The techniques seen here are magnetic resonance imaging (MRI), X-rays (radiography) and artworks. MRI scanning (like the sideways slice through the head) uses radio waves and a powerful magnet to obtain slice images through the human body. X-rays (like the lower spine and pelvis) reveal body tissues by their differing transmission of X-rays. The heart has also been imaged using X-rays. These techniques can be used to diagnose disorders within the body. The artworks include arm muscles (left) and arm blood vessels (right), as well as leg muscles and blood vessels (right).
