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), dissection 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 half of the pelvis at right and both hands) show body tissues by their differing transmission of X-rays. These techniques are used to diagnose medical disorders. The thigh at left has been dissected vertically. The various artworks include the rest of the arms, the lungs and the heart, as well as the digestive organs.
