  1. I am happily still using my mid-2010 17" MacBook Pro with an ancient nVidia M330 graphics card and i7 core processor. It was one of the last 17" screen models released. I also have Bootcamp installed and run two separate upgraded SSD drives: One for Windows 10 and one for MacOS El Capitan. I can use all software interchangeably on either operating system and have them duplicated on both drives for easy workflow. Exception is OsiriX on Mac only and 3DEditPro from 3DSystems on Windows only. 3DSlicer works equally well on both platforms, as does Blender, Meshlab, Meshmixer, and Netfabb Basic. Those are my main tools. The 6 year old laptop slows down with 3D meshes over 1 million triangles, so if you have a need for ultra high resolution meshes then you need a modern dedicated graphics card. I've found no reason (yet) to have meshes over 500K triangles and usually decimate (simplify) well below that even for 3D printing. The 17" screen (without workstation dedicated monitor when available) is great perk these days. So is Bootcamp dual boot option for greatest number of options. That said, MacBook Pro is excellent choice for this work even if you choose to install and work only in OSX environment with open source software (including 3D Slicer). You may run into problems with proprietary licensed software (esp from hardware vendors that bundle software tools) supporting Windows only as part of typical enterprise culture. That's the only benefit I can see of having a Windows machine or virtual machine. Hope that helps.

  4. This is a gallery of sample pics of 3D printed medical models we made at entrescan.com.
  5. Yes, please. The rendered 3D model (.stl file) should be anonymous, meaning free of any personal identifying information or any headers or metatags from the DICOM data and therefore HIPAA exempt. I agree it is still a good idea and professional courtesy to request permission from the clinician who obtained and supplied the DICOM data to you. If you can upload these anonymous craniofacial .stl files to the marketplace then other members of the community (like myself) can use them for educational projects. Also supplying clinical diagnosis would be very helpful. Thanks!
  6. Hi Amir, Would you please mind posting your pediatric craniosynostosis case to the marketplace as a downloadable file (or for sale)? My company is collecting some pedi craniofacial cases for an anatomy project at a medical school in our area. Thank you for considering it, and please let me know if it's not possible.
  7. Dr. Mike, just curious what software you like to use to record, mix, edit, soundtrack, etc your excellent instructional videos and presentations here and on your YouTube channel? Consider this an educational meta-post. Are there pros and cons to different tools to screen capture video and/or incorporate your camera-view mode from your laptop (like Skype mode) to integrate a personal interview with the screen captured desktop software and/or imported video from a file, etc? Staying with the general theme of your forum, is there a good freeware tool you like?
  8. The best value of this forum is high quality instruction and tutorials for proper 3D modeling, emphasizing freeware whenever possible. I would love to see more tutorials for various techniques relevant for different models and different use cases. Lumen wall thickness, for example, comes to mind discussed in another thread could be its own tutorial as it is a common procedure for different 3D medical models (not only vascular). Proper segmentation of a tracheal airway would be another great topic.
  9. I've been playing with "solidify" and "hollow" options in Meshmixer to create a vascular lumen with mixed results (hollow works much more predictably than solidify). Am I to understand that Blender or perhaps Mimics are the only other software that do this? Does Meshlab or any other (free) software have a feature to control vascular (or airway, duct, etc) wall thickness? It sounds from this discussion like Blender is the freeware package to learn in order to do this correctly for now, but I'm trying to specialize in non-Blender software as we have a Blender specialist where I work. So far I've seen alternatives and work-arounds for anything Blender can do for 3D modeling, even if it's in different packages or even combinations of other software. But wall thickness control is a big deal for vascular models. Is it time to bite that bullet and dive into Blender?

  12. I've recently discovered two similar peer-reviewed online journals that publish articles related to 3D medical modeling and printing. The first is based out of North America called 3D Printing in Medicine: http://threedmedprint.springeropen.com/articles The second is based out of Australia called Journal of 3D Printing in Medicine: http://www.futuremedicine.com/loi/3dp Let me know if anyone has any feedback about the quality or submission process for papers. Both just started.
  13. A client asked me if "3D mammography" can be segmented and rendered as a medical model. I'm not familiar with 3D mammography. Is this possible to do?
  14. Q&A with Mayo Radiologists about 3D print lab as surgical service: http://tcbmag.com/News/Recent-News/2016/April/Q-A-How-Mayo-Is-Integrating-3D-Printing-Into-The-O
  15. What imaging did you use for these breast models? Someone asked me if 3D mammography can be modeled. I'm not familiar with 3D mammography, but is it suitable to render a model?
