skull ashtray

The other day a friend had a serious bike accident followed by some CT and MR scans and eventually a brain surgery. He's kind of OK now BTW.

However of course the first thing I had to ask was for his scans. Many were optimized to visualize the cerebral hemorrhage so most of them had his lower jar cut off unfortunately.

But there was this one beautiful scan which made it possible to extract the skull from it with this excellent open source software 3d slicer ( www.slicer.org ). Unfortunate
