Fascinating post about using a RasPi to explore Diffusion MRI analysis, shared over at RaspberryPi.org:
I wanted to try the same sort of analysis that a researcher working in my field might want to use. The simplest and most widely used technique in Diffusion MRI is called Diffusion Tensor Imaging (DTI). The brain is partly made up of a thing called white matter, which is a lot like cabling that connects various bits of it together. DTI can tell us which way the cables are pointing at each point along their length. We can use the information it gives us to make new images which are more useful than the originals.
To my great delight, the Raspi ran a DTI analysis in a little over 5 minutes and produced some really nice images. All these images were generated and displayed by the Raspi. (Liz: you can enlarge all these images by clicking on them.) I used scrot for screen captures, so aside from a little cropping this all is pure Pi….
