The basic principle and the technical development of imaging formation using NMR were proposed by Lauterbur, who developed the MRI (Lauterbur 1973). The Nobel Prize in Medicine and Physiology was awarded in 2003 to Lauterbur and Mansfield for the fundamental application of a static magnetic field in combination with a gradient (timevarying) magnetic field and the development of the image acquisition and processing (Mansfield and Maudsley 1977). In this way, the root of MRI is known as nuclear magnetic resonance. To avoid alarming the public and medical experts, the word “nuclear” was deleted from the term magnetic resonance, although it has nothing to do with radioactivity.
