can now be able to be amplified with the help of a new technique
that improves the signal strength by up to 10,000 times,
according to new research. By using xenon gas which has been
altered using laser light, the molecules in atoms are
manipulated so that most of them are facing the same way, which
allows a clearer picture to be constructed. Alexander Pines, who
led the development of the Hyper-SAGE technology at the Lawrence
Berkeley National Laboratory and the University of California,
pointed out that the tool could be useful for molecular imaging
and in vivo diagnostics. Mr Pines explained: "It is absolutely
amazing because we're looking at pure gas and can reconstruct
the whole image of our target." A recent study at the John
Hopkins University School of Medicine showed that a one-minute
eye movement exam is more effective than an MRI scan in
identifying whether a patient is suffering from a stroke or
something less serious.
