I haven't uploaded in a while, so here is a copy of my brain. Print it out and place it in a robot, and it will make 3D models for you and post them here! ;)

I recently got an MRI to check for brain masses (all clear!), and the doctor, noting me as the curious type, mentioned I could get my data on a CD for free. So I did just that, then I used this script to convert the data (over the course of 16 hours) into a 3D recreation of the surface of my cortical and subcortical structures! I made a little stand for it, too!

If you want to do this with your own MRI data, the easiest way is to use this Docker image I made. It has all the dependencies for the above script (FSL, Freesurfer, a bunch of things from apt-get), plus additional tools and scripts to make the conversion process as painless as possible. The readme is also written for a non-technical user.

The EGJ_brain.stl and EGJ_brain_stand.stl are the "final" outputs. There may be some printability issues, I couldn't for the life of me fix them. The remaining files are the raw outputs from the surface reconstruction algorithm.

You can use this for whatever you like. The only requirement from me, the copyright holder, is that you clearly credit me as the source of the model, alongside any other credits for the project it's used in.

UPDATE: I ran the conversion again and got slightly different results, which I've uploaded here. The cortical structure is almost exactly the same, with arguably better definition in some areas. It's hard to say, seeing as I can't take my brain out and look at it. The subcortical structure could not be captured for some reason this time. Quite odd, because the input files were exactly the same. I did rebuild the Docker container, so perhaps a software update changed something. Or maybe there's some randomness involved in the surface reconstruction process. IDK.
