  1. Devarsh, your article is spot on. MRI is incredibly valuable, but there are huge limitations to 3D printing from it. Usually, I am stuck with doing a lot of manual segmentation, which is extremely time consuming. Thanks for writing this great article!
  2. I've never heard of this. It almost sounds too good to be true. Anybody have experience with this?

    I think you can use 3D slicer. Here is a forum discussion on the topic. https://discourse.slicer.org/t/open-tiff-files/1494
  4. You are very welcome. We really try to listen to all member feedback, and appreciate it when people take the time to let us know about a problem. Thank you.
  5. Agreed. This limit was put in place to prevent abuse for free downloads, but should not apply to paid items. We are working on a fix. You should now be able to download your files. Thank you for letting us know about this issue.

    Postprocessing 3D prints

    You can use a variety of free tools, including Blender or Meshmixer. Meshmixer is probably easiest. Here is the function shown in this picture.

    Skull is seen as two shells

    Kopachini is correct. You need to close the open hole.

    This 3D printable model of a normal human heart was generated from an ECG-gated contrast enhanced coronary CT scan. The slices are cut to illustrate the echocardiographic short-axis view. If you are interested in a 3D printable heart that shows slices in the anatomical transverse plane, click here. Notches have been added to ensure the slices fit together and do not slide against each other. The model demonstrates the detailed anatomy of the human heart in exquisite detail. Each slice stacks on top of the prior slice to form a complete human heart. There is a sturdy and stable base. Individual slices show the detailed cardiac anatomy of the right and left ventricles, and right and left atria, and outflow tracts in echocardiographic short-axis projection. Perfect for educational purposes. Technical parameters: Individual STLs: 4 Mesh integrity: manifold STL (watertight) vertices: appx 550k per object triangles: appx 1.1M per object dimensions: 11.4 x 9.1 x 10.6 cm


  9. We recently 3D printed a multimaterial skull with MCA aneurysm from a CTA head for customer who needed the skull in rigid plastic and the vessels and aneurysm in flexible material. The model will be used by neurosurgeons to practice intracranial aneurysm clipping surgery. To properly simulate the surgery, the skull needs to be hard and the vessels elastic. Combining two materials (and two printers!) provides the best solution. The model was created on democratiz3D. You can learn more about embodi3D's printing service here.
  10. Hi Dr. Mike. how you doing?

    I'm currently working on simulation of blood vasculature in kidney using graph-based methods as my MSc project. I need some CT scans of kidney. Could you help on that?

    My problem is i can not find a CT scan where the renal pyramids are clear enough.

    Lumbar Spine 3D print

    You might want to check the spine and pelvis download area. https://www.embodi3d.com/files/category/13-spine-and-pelvis/
  12. Thanks for sharing the link Josip. Nice work!
  13. There is a Medical 3D printing conference in Germany this May. Materialise has a conference in Belgium this June. There is a smaller conference run in Basel Switzerland. Here is the link from last year (none available this year yet) I am still looking for North American conferences. Will post if I find any.
  14. No, unfortunately it was cancelled for this year. I think the 3D printing conferences and workshops are going to organized by the RSNA 3D Printing Special Interest Group going forward, but I am not sure if they have determined an exact time and place yet. I highly encourage you to attend these conferences. They are highly informative and all the major groups doing medical 3D printing work (Mayo, Ottawa, Walter Reed, Stanford, VA, etc) will be attending and probably so will I! I will inquire with the RSNA 3D Printing SIG about the schedule of upcoming meetings and post a response here. Dr. Mike

    image extraction

    You need volumetric (3D) data, not 2D angiographic data. Unless you have a CT or MRI, angios wont work. You could potentially do a cone-beam CTA in the angio suite if you have the right software though. kopachini, thanks for helping out this member with your response. Dr. Mike
