BRAAAAAAIN! by gianteye

Description

I know you want to print a brain of your very own. Observe this lovely normal brain. I downloaded the raw mri files from bit.ly/7d9TFA and converted them in 3d-doctor.com/

3dDoctor can output some pretty messy STL's so you'll probably want to fix them up in NetFabb or another mesh repair tool.

Instructions

Print both halves and glue together. Share and enjoy.

I've figured out a pretty decent method for getting MRI information through 3dDoc.

1. RAW formats seem fairly common for MRI slices. Take note of the number of slices and the x/y dimensions { mouldy.bic.mni.mcgill.ca/cgi/brainweb1?alias=subject04_crisp&download=1 }. Even tiny mistakes inputting these data can screw up your import like bad tuning on a tv.

2. File > Import RAW takes you to a pretty simple wizard for selecting out your key components in your scan. 3dDoc is designed for isolating individual organs/volumes based on density { en.wikipedia.org/wiki/Magnetic_resonance_imaging }. The wizard will take you to a menu to select out the range of densities you're looking for with a slider tool. Remember to apply the filter to all slices.

3. When you've completed the wizard you'll be looking at a pretty detailed 3d model. You can go back to the slices and render out a lower quality version through Model > Complex Render and setting the values higher than 1. Save your result as STL and check the file size.

4. I've taken my models into NetFabb { netfabb.com } to repair them, scale 'em, and slice 'em into reasonable printable sections. You can take any MRI scan and make multiple models from the result by selecting out different densities. Try it for yourself.
