In this, new voyages of discovery are being prepared: In those images, we will be able to discern not only structure, but also function, physiology, or biochemistry.

10. 上海第二医科大学 物理教研室 The 2003 Nobel Prize in Physiology or Medicine The Nobel Assembly at Karolinska InstitutetThe Nobel Assembly at Karolinska Institutet has today decided to award The Nobel Prize in Physiology or Medicine for 2003 jointly to Paul C Lauterbur and Peter Mansfield for their discoveries concerning "magnetic resonance imaging"

11. 上海第二医科大学 物理教研室 Paul Lauterbur Discovered that two-dimensional images could be produced by introduction of gradients in the magnetic field. Discovered that two-dimensional images could be produced by introduction of gradients in the magnetic field. By analysis of the characteristics of the emitted radio waves, he could determine their origin. This made it possible to build up two-dimensional pictures of structures that could not be visualized with other methods.

12. 上海第二医科大学 物理教研室 Peter Mansfield Discovered that use of gradients in the magnetic field gave signals that rapidly and effectively could be analyzed and transformed to an image. Discovered that use of gradients in the magnetic field gave signals that rapidly and effectively could be analyzed and transformed to an image. Mansfield also showed how extremely rapid imaging could be achieved by very fast gradient variations (EPI). This approach became possible in clinical practice a decade later.
