Spin warp NMR imaging and applications to human whole-body imaging

Methodology of magnetic resonance imaging

“…Spin-warp imaging, proposed by Hutchison and co-workers (Edelstein et al 1980;Johnson et al 1983), represents a variant of Fourier imaging which turned out to be particularly easy to implement and has been very successful in commercial instruments.…”

Magnetic Resonance Imaging in Medicine: Quantitative Tissue Characterization

“…With careful design the electronic noise component can be made negligible. and the image noise then is 20 N ex fw2 + aw ~ /B'N" , av (9) where a is the factor which describes the effective coil noise temperature versus the specimen noise temperature. With high efficiency coils, and especially at higher frequencies, the specimen noise dominates the coil noise (aw~ «w 2 ).…”

Magnetic Resonance Imaging: From Spin Physics to Medical Diagnosis

“…Research in MRI was pursued only in a few academic laboratories, mostly in the UK, with the first image of a human thorax in 1977, of a head in 1978, until 1980 when Edelstein, in Mallard's team in Aberdeen, obtained the first clinically useful image of a patient [17]. After this date, several companies started to invest in MRI developments and to promote clinical trials.…”
