Continuing from a different thread, where this has come up.
I knew that they were using super conductivity for magnetic scanning of brain waves. They say it is better than using electrodes. But liquid Helium, not even liquid Nitrogen temperature yet?
And then scanning the heart? And an in utero fetal heart?
And then using ferrites, and TDK claiming to have invented ferrite? You need ferrite anytime you want an RF transformer, like for a herteodyne radio receiver. 1920's?
Do they do a mapping and an inverse 2-D spacial Fourier transform to make an image?
Want to know more about this.

Way back I was helping out in a lab that was looking at liquid helium near absolute zero. This had something to do with superconductivity. One of my professors was known as 'the father of cryonics' because of a book he wrote. I had the impression that back the military was funding this research in the universities.
