High Dimensional Geometry Is Transforming the MRI Industry (2017) [pdf] | Hacker News

A Hacker News discussion highlights how high-dimensional geometry and AI are improving MRI and fMRI analysis.

The thread notes that these scans are noisy and indirect, yet modern methods can extract far more useful signal than before.

Examples include reconstructing viewed images from brain activity, showing how brain scans can be turned into richer information.

Commenters argue that abstract mathematics plus AI could improve diagnosis and help reduce the high cost of MRI scans.
