creating microreticulations on flowing blood as well as tissue with multihysteresis MRI contrast agents

Yowza! magnetic field interference patterns (||||||) make durable reticulations on a contrast agent, meanwhile the really rapid MRI pulses image the tissue generally, yet are too rapid to modify the contrast agent much. The regular ||||| improves software imaging perhaps two or three times, similar to the way laser systems improve with a reticulation guide

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.

       It would be fascinating to put your brain under an MRI sometime.

       In some strange way, my mind has been trained to be able to spot a beanangel post at 100 paces...   

       I'm not sure I approve of that usage of my neurons.   

       Give me back my neurons! I might need them for something later..like..ermm..

       Is this the longest title ever to appear on the HB?

       not even the longest B.A. title.
