>The scanner needs a static field that's homogeneous over the region you're imaging. Does it? Couldn't you let go of that assumption with heaps of compute powe

  What would you do with the compute power? There are some ways to correct for field inhomogeneity, but there are also fundamental limits like shorter signal lifetimes (or analogously bandwidth requirements) in inhomogeneous fields that you can't really get around. It's always possible there will be some advance, but I'm not aware of compute power as any real bottleneck
