Dear friends, I share with you the link to the high quality printable knee biomodel. The biomodel was segmented by separating the bones into: Tibia and Fibula, Femur and Patella, so it is possible to print each bone separately. The 3D biomodel has the patient's real dimensions. Link: I also place myself at the disposal to carry out any type of segmentation that you are looking for. I appreciate the attention and if you can share the link with other colleagues, I will be grateful. Sincerely, Vitor Urel.

The knew biomodel was created from 0,7mm CT scan. In the biomodel it is possible to distinguish the bones: Tibia, Fibula, Femur and Patella. The biomodels of the bones have been segmented and are separated. There is also a file of the skin of the knee region.$5.99

Biomodel of the rib cage made from a 7 mm computed tomography scan of a 20-year-old man. The model includes: 1. STL of the full rib cage Triangles: 545k 2. STL of the rib cage with simulation of a rib fracture Triangles: 673k 3. Rib STL (simulation) Triangles: 210k Models can be printed in 3D. CaixaToracicaBiomecanica v2.mp4 RIB CAGE.pdfFree

Thanks for the answer. Certainly, when performing these subsequent segmentation steps, the biomodel will be better defined. The next biomodel that I do I will adopt this methodology and see the result. The work done with the liver and vena cava is impressive. Do you recommend me any material or video to go deeper into the practical use of segmentation techniques? Thank you very much. Regards, Vitor Urel.

How can 3D printing help with the coronavirus pandemic?
VitorUrel replied to Dr. Mike's topic in Medical 3D Printing
In Brazil, many research groups and enthusiasts have contributed to develop face shield to combat the pandemic. I had the opportunity to participate in development and logistics in the Higia group (https://www.projetohigia.com.br), distributed more than 100 thousand units throughout the country. The 3D models were developed in partnership with doctors and health professionals and are available on the project website. Regards, Vitor Urel. -
CT images are segmented by a difference of threshold values. Therefore, tissue that present less contrast to each other are more difficult to generate good results with automatic segmentation. As mentioned above, for bone biomodels, many of the software have good results, but even with them it is necessary to perform a computational modeling afterwards, to clean noise and unwanted parts that appear in the segmented biomodel. I have used the InVesalius software (https://invesalius.github.io) for many of the biomodels that I have created. I believe that to achieve High quality in the final result, dedication to the creation of the biomodel is still necessary. I hope I contributed to the discussion. Regards, Vitor Urel.
