So for the last 5-6 years I've been working on a new class of small footprint MRI that could go in doctor's offices (without NIH funding he adds bitterly - submitted the grant 5 times and it was always rejected with "too high risk"). Well it works baby. Got signal last night!

Will it be substantially cheaper than the bigger machines, both to buy and use? Is there a market need for this?
-
At least a factor of 10 cheaper - hopefully more. This could make MR more accessible and require fewer trips to the hospital for more expensive scanning.

From the picture, does this have application for upright (standing) spinal or cranial imagery? As a patient better access to that kind of dx info would be very meaningful!
-
Yes! It could also be made in different shapes and sizes depending upon the application.

Two questions, 1 power requirements for that magnetic field? 2 how far away do you have to stash ferromagnetic objects during operation? Doctors offices can be mighty cramped sometimes. Other that that, fantastic idea
-
Good points. It does have a kick-ass power amplifier right now but we have some ideas as to how to do this with permanent magnets too so that would go away. The 5 Gauss line is about 5 feet away, but because it's an electromagnet it can be turned off when not used.

Very cool. Telsa strength?
-
It's a field cycling magnet. Right now it polarizes at 0.3T and readout is at 1MHz (24mT). Optimum to be determined.
