MRI modified for better images
Action-at-a-distance offers more spacious machines.
A simple change to magnetic resonance imaging (MRI) machines will provide more uniform coverage at higher powers as well as more room for portly patients. In a market set to be worth more than $5 billion by 2010, the new technology may offer an easier way to get to the high-field machines manufacturers and clinicians see as the next target for hospital imaging.

Metabolism and especially photosynthesis involve triplet species whose unpaired spins align in a strong magnetic field, altering chemistry. The Bohr magneton is 1836 times larger than the nuclear magneton. Seven tesla need not be biologically inert - especially on instrument entry and exit with violent edge and inductive effects. Nobody has grown Arabidopsis thaliana from seed in a 7 tesla, high gradient, high divergence magnetic field (hydroponics). Somebody should look. If not rockcress, then Matthew 6:28.
