Magnetic Resonance Imaging (MRI) - DESY
www.desy.deMagnetic resonance imaging (MRI) is a spectroscopic imaging technique used in medical settings to produce images of the inside of the human body. ! MRI is based on the principles of nuclear magnetic resonance (NMR), which is a spectroscopic technique used to obtain microscopic chemical and physical data about molecules !

Principles of NMR
process-nmr.comNuclear magnetic resonance spectroscopy (NMR) was first developed in 1946 by research groups at Stanford and M.I.T., in the USA. The radar technology developed during World War II made many of the electronic aspects of the NMR spectrometer possible. With the newly developed hardware physicists and chemists began to apply the

mymission.lamission.eduNuclear Magnetic Resonance Spectroscopy • When a charged particle such as a proton spins on its axis, it creates a magnetic field. Thus, the nucleus can be considered to be a tiny bar magnet. • Normally, these tiny bar magnets are randomly oriented in space. However, in the presence of a magnetic field B
