Converting Video if a Brain MRI Scan to a Mesh in Blender


cogitas3d writes:

Some days ago I read on Science News Magazine a story about a high definition MRI made on a human brain. In the video presented on the story was possible see the slices of MRI and I thought that it could be a good opportunity to test some tools on Linux 3DCS and OrtogOnBlender.

So this was the step-by-step:

  1. Download the video with Video DownloadHelper;
  2. Convert video into an image sequence with FFMPEG;
  3. Force a conversion to grayscale with ImageMagick;
  4. Select only a half of more than 1200 slices, because it can crash the computer;
  5. Convert grayscale sequence into a DICOM sequence (inside OrtogOnBlender);
  6. Reconstruct the voxel data from DICOM;
  7. Reconstruct 3D mesh from DICOM.

Step-by-step video:

I hope you enjoy. A big hug!

  1. Awesome, you are superman. I hope Intel or AMD and Nvidia help donate their technology too or hardware give it to you.
