The way to images inside the human body information an issue. Three-dimensional information obtained since the shooting method based on the physical properties of the substance produces the image seemingly x-ray computed tomography and computed tomography that is similar, but totally different from CT CT （ has been become gain recent CT ） gained more.
2003, Recognized its importance in medical MRI and application, and Nobel Prize in Physiology or medicine for "discoveries concerning magnetic resonance imaging", given to Paul lauterbur and Peter Mansfield.
Paul lauterbur (Wikipedia) than Paul Christian lauterbur (Paul Christian Lauterbur, 5/6/1929 - 3/27/2007) is a chemist in the United States. Discovery to allow the development of magnetic resonance imaging (MRI), along with Peter Mansfield won the 2003 Nobel Prize in Physiology or medicine.
His original MRI is a New York State University at Stony Brook on Long Island. Born in Ohio. Having served Professor University of Illinois at Urbana-Champaign in 1985, New York State University of Stony Brook, since 1969.
3/27/2007 Finished the life of 77 years. -----------------Omiya nobumitsu / by "50 discovery / invention of modern chemistry" Science-I published in new book 2012 invention of the MRI was awarded the Nobel Prize in 2003 (some excerpts line MRI inventor lauterbur and Mansfield) was followed by development of x-ray CT 1979-winning medical engineering feat. Is the same slice Imaging different principles of MRI and CT scans. X-ray computed tomography uses a kind of radiation X rays, unlike x-rays is that computer calculate the data taken from different directions, turning the detector around the body and shrugging.
Reconfigure the body this way of doing even a three-dimensional absorption distribution image. MRI contrast using magnetic field nuclear magnetic resonance (NMR) phenomenon, get cross-sectional images. Magnetic field on the nuclear Zeeman splitting, splitting the two energy levels available. Zeeman splitting is possible in one orbital electron takes two possible spin States （ spin phenomenon because it is possible. One analogy, two humans normal standing and standing there. Two spin States is same with no magnetic field energy. Nuclear magnetic resonance can energy between two States but that the Zeeman splitting. Nuclear magnetic resonance why does a difference in energy? If standing human stands than usual hard, energy consumption. However, there is no difference in energy with standing and standing, so that gravity does not exist in outer space without difference of upper and lower case. This is the Earth that energy comes out difference.
Zeeman splitting is equivalent.Most of the biomolecules that make up the human body contains a myriad of hydrogen nuclei. Nuclear spin orientation apart's at this rate, put the human body this nuclear constant intensity magnetic field in its nucleus to be like tiny electromagnets, which spin in the same direction. Eliminate the magnetic field also would be to spin and status, i.e. various direction as. However, to restore the original time different every human organization.
From MRI Plus magnetic fields to humans once removed, measure the time state of the hydrogen nucleus back under the State, stereoscopic images the difference in the computer. -Announce, until 1973, finally, Paul lauterbur of the United States proposed principle the principle of simple and important images, and a linear magnetic field gradient. To give a slight gradient magnetic imaged as resonant frequency shift in Fourier transform world space position information.
Compared to the back until the hydrogen nuclei to State and 1977, United Kingdom Peter Mansfield's time in irradiated with less high frequency pulse trains, was to give the images at high speed. Thus practical MRI shows more visceral State because no practical radiation exposure and bone does not reflect. Image contrast is excellent in many respects than crisp, than x-rays, will revolutionize medical practice. Most use magnetic, so can't use MRI to or embedding metal body.
Contrary to examine bone disease in MRI are very helpful. -----------------Paul lauterbur Google search http://www.google.co.jp/images?hl=ja&rlz=1T4GZAZ_jaJP276JP276&q=%E3%83%9D%E3%83%BC%E3%83%AB%E3%83%BB%E3%83%A9%E3%82%A6%E3%82%BF%E3%83%BC%E3%83%90%E3%83%BC&gs_l=hp.
