I was looking at some of the audio applications of Nupic provided by a helpful
person on this list, and I think the same methods could be used for an MRI
application.
Static MRI pictures are constructed from Fourier transforms of a signal
produced by Hydrogen atoms spinning under the influence of MRI magnets. They
are then converted into a picture. So temporal is converted to spatial or vice
versa. I’m somewhat muddled on this, but my brother creates sequences for MRI
machines and then gathers the data coming out, and I want to interest him in
Nupic.
MRI static pictures are usually used to look for anomalies like tumors, or soft
tissue problems that do not show up on x-rays. It might be hard to compare a
pathology picture with a healthy picture because people vary in height and
shape etc. That could be a problem – there is no standard picture of a lung
for instance – you would have to feed pictures from people of all sizes into
the HTM.
There would be no need for a step of converting the signal to a picture,
instead the signal would be fed directly into Nupic.
There is also Functional-MRI – which can watch movements – you can watch a MRI
movie of a heart beating and look for anomalies there.
So is this something I can present to my brother’s research team at his
university, and if so, are there any special methods that should be used?
Thanks.
