What if contrast agents at MRI automatically produced
regular ||||||| (reticulation) patterns wherever they
were at the body, giving focus guidelines to MRI image
processing software.
MRI contrast agents are just chemicals, already fda
approved, that are particularly susceptible to
magnetism(easily
spin polarized).
Similar "artificial optical reference" systems with laser
optics get 2 or 3 times higher resolution as a result of the
software using the optical reference to know whats
what.
I think with two magnets separate from the actual MRI
machine, you could make magnetic interference
patterns, basically overlapping wave fringes that would
create "stripes" or reticulations at an MRI contrast agent
flowing through the bloodstream. This MRI agent could
have "wide" hysteresis diagram, that is it would take an
entire 1/100th of a second to magnetize, then stay that
way like a 20th of a second.
Meanwhile the MRI machine would be making normal
rapid millisecond high magnetic field imaging pulses, as a
result of the contrast agents wide hysteresis
(gradual)magnetism the effect on the "stripey" magnetic
contrast agent from the mri scan pulse would be minimal
yet the detector would see both the magnetic contrast
reticulations at tissue depth, as well as the normal MRI
data. the software would then use the defined shapes to
improve image processing. if necessary the magnets
could make an (erase then redraw) duration reticulation
pulse at intervals.
This is a different than using a superconductive meissner
screen to create reticulations at tissue depth to improve
image processing.
Physically It might look like a couple electromagnets on a
ping pong paddle near the body surface, at the large gap
between the body n the actual MRI machine.
