"NANOTECH: IBM claims highest resolution MRI"

IBM Corp. will demonstrate what it claims is the world's first nanoscale MRI capable of imaging structures as small as 103 atoms. Called magnetic resonance force microscopy (MRFM), the new technique takes a page from atomic-force microscopy to overcome the sensitivity limitations of a conventional MRI. Using a magnetic-force tip capable of 1.4 million Tesla/meter fields rather than conventional induction coils, IBM's MRFM is said to be capable of spatial resolutions of better than 90 nm, compared to 3 microns for the best conventional MRIs. IBM also said it was able to image volumes as small as 650 zeptolitres, 60,000 times smaller than the previous record holder.
