Standard hospital scanners have a spatial resolution of about 1 millimeter, covering about 10 000 neurons, and a time resolution of about a second. The INUMAC will be able to image an area of about 0.1 mm, or 1000 neurons, and see changes occurring as fast as one-tenth of a second, according to Pierre Védrine, director of the project at the French Alternative Energies and Atomic Energy Commission, in Paris

A stationary magnetic field cannot heat and burn patients. What you are referring to is radio frequency heating, caused not by the magnetic field but by the radio waves used to do the actual probing. You do not need to increase the RF power to make use of the increased resolution offered by higher magnetic fields.

Yes, this is true -- but only if the patient is also stationary. Which they aren't, usually; see 4. It's true that the vast majority of MRI burns are not of this type, but I'm aware of some examples.

Right, my phrasing in 4 is a bit bad. However, I'm not referring to RF in 1.
