MRI - MAGNETIC RESONANCE IMAGING

摘要

On October 6th 2003, while some of us were en route to the General Assembly in Lisbon, the Nobel Assembly awarded the Prize in Physiology or Medicine for 2003. The prize was shared by Paul C. Lauterbur and Peter Mansfield for their discoveries concerning 'magnetic resonance imaging'. Dr Lauterbur 'discovered the possibility to create a two-dimensional picture by introducing 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. Dr Mansfield showed how the signals could be mathematically analyzed and how extremely fast imaging could be achieved.
