George Eugene Uhnlenbeck
26
What year did Professor Isidor I. Rabbi : -observed the quantum phenomenon dubbed nuclear magnetic resonance (NMR) -recognized that the atomic nuclei show their presence by absorbing/emitting radio waves when exposed to a sufficiently strong magnetic field
1937
27
what year: -detecting & measuring single states of rotation of atoms & molecules & in determining the mechanical & magnetic moment of the nuclei -influenced by Cornelius Jacobus Gorter
1930

-Dutch Physicist -detecting & measuring single states of rotation of atoms & molecules & in determining the mechanical & magnetic moment of the nuclei was influenced by ______
Cornelius Jacobus Gorter
29
What year: - he & his co-worker Broer, reported unsuccessful attempts to observe nuclear magnetic resonance in pure crystalline materials -first to demonstrate the phenomenon of paramagnetic relaxation
Sept 1937
30
(1907-1976) -A Soviet Physicist -discovered electron paramagnetic resonance in 1944
Yevgeny Konstantinovich Zavoisky
31
-discover magnetic resonance phenomenon -Nobel prize for physics -measure magnetic resonance in bulk material such as liquids & solids
Felix Bloch & Edward Purcell
32
(Stanford University)
-Felix B.
33
(Harvard University)
-Edward P.
34
-an American Physicist -Nuclear induction -together w/ his colleagues, did an experiment measuring an electromotive force resulting from the forced precession of the nuclear magnetization in the applied RF field
Edward Mills Purcell (1912-1997)
35
what year: birth of MRI
1952
36
creates 1 dimensional image
-Herman Carr-
37
Magnetic Resonance was discovered
1946
38
-further developed the utilization of gradients in the magnetic field and mathematically analysis of these signals for a more useful imaging technique -gradient coils -showed how signals can be mathematically analyzed which later gave way to EPI technique in 1977
Peter Mansfield
39
the first ultra-high-speed imaging technique; fast high speed imaging technique
-EPI (echo-planar imaging);
40
were awarded with the 2003 Nobel Prize in Physiology and Medicine
-Paul C Lauterbur & Peter Mansfield
41
MRI; receive frequency
*coils
42
detectors
CT
43
casette
X-RAY
44
what year: -“Tesla Unit” was proclaimed in the Rathaus of Munich, Germany by the International Electro-technical Commission-committee of action. -all MRI machines are calibrated in “Tesla Units”
* 1956
45
measures strength of a magnetic field -the stronger the amount of radio signals which can be elicited from the body’s atoms and therefore the higher the quality of MRI images
-Tesla or Gauss unite;
46
demonstrated with his NMR device, that there are different T1 relaxation times between normal and abnormal tissues of the same type, as well as between different types of normal tissues
Raymond Vahan Damadian
47
-a physician and experimenter working at Brooklyn’s Downstate Medicall Center discovered that hydrogen signal in cancerous tissue is different from that of healthy tissue because tumors contain more water
Raymond Vahan Damadian
48
-hyperintence (light)
*T1
49

51
first MR scanner name
(Indomitable)

what year: -Raymond Damadian applies for a ptent, which describes the concept of NMR being used for above purpose. -He illustrates major parts of MRI machine in his patent application
* 1972
53
in 1973, described a new imaging technique that he termed Zeugmatography -By utilizing gradients in the magnetic field, this technique was able to produce a 2-dimensional image (back-projection)
Paul Lauterbur
54
what year: -Paul Lauterbur, a chemist an an NMR pioneer at the State University of New York, Stony Brook, produced the first NMR image. It was of a test tube
* 1973
