  1. Here are some tutorials to get you started: 1) Easily create bone STL files using a the democratiz3D automatic conversion service. 2) Create bone models on your desktop Mac with Osirix, Blender, and Meshmixer. 3) Create bone models on your desktop Windows PC with 3D Slicer, Blender and Meshmixer. 4) A comparison of the desktop versus online methods of making simple bone models. Good luck!
  2. Did you know you can create muscle and ligament models from CT scans using the democratiz3d service by changing only one setting? Here is a tutorial on how to do that. As far as the scanning goes, the most important thing is to make sure you are using a CT scan. Most knee imaging is MRI for things like ligament and cartilage tears. If you wish to view and rotate your model, I suggest downloading it and then manipulating the STL file it in meshmixer. That will allow you to turn and view it as you see fit. hope this helps
  3. Glad this is helpful to you!
  4. I think embodi3D member mikefazz has experience making 3D printable splits. You might want to reach out to him.
  5. Thanks to mikefazz for posting this great tutorial on MRI segmentation using the fastgrowcut tool. Be sure to check it out.

  11. The problem isn't the voxel size, but rather the voxel value. In other words, a value that is 10 hounsfield units (water) becomes 32000 or so in fiji. I'm thinking that the voxel values are as a signed integer but fiji reads it as an unsigned one. Not sure but anytime I use fiji I seem to run into this problem.
  12. This is an area of active debate and discussion. The FDA is evaluating the situation and still working on recommendations and guidelines for surgical guides. Nobody knows what the regs should be, including the FDA. Its hard to keep in top of the latest recommendations since they are constantly changing. Here is an article written by the FDA workgroup on 3D printing. Here is a link to the FDA page on the topic. Hope this helps.
  13. Researchers at UC San Diego have successfully 3D printed a network of blood vessels. This is an important step towards 3D printing an entire organ. Read the full story here.
  14. I've noticed that Fiji alters voxel values when an imported TIFF stack is saved as NRRD file format. Voxels are about 32,000 higher than they should be. This causes problems when running the NRRD file through the democratiz3D conversion service. as the values are well outside the normal range. Does anybody have experience with Fiji and have a solution to this problem? Thanks in advance. Dr. Mike
  15. Great post Mike. Thank you.
