  1. That's a great news... I hope that there will be a windows version, too, so others who don't use Linux could also try it
  2. Version 1.0.0


    This is an ready-to-print .stl file of neonatal skull with a rare congenital anomaly of one sided maxillary and mandibular fusion and mandibular cleft (which is little bit reduced for more easier print). Also, connections between cranial bones were added. Could be printed on FDM (slightly harder to remove supports) and SLA/DLP 3D printer. head, skull, .stl, 3d, model, printable, frontal, parietal, congenital, syngnathia, orbit, nasal, spine, hard, palate, mandible, maxilla, zygomatic, arch, angle, ramus, coronoid, process, bone, metopic, suture, coronal, fontanelle, anterior, posterior,


  3. Unfortunately, I won't attend RSNA meeting this year
  4. Version 1.0.0


    Palatine bone of a young female. Segmented according to Sobotta Anatomy atlas. Model is printable on FDM printer and others.


  5. This was eye openning for me, now is so much easier for me to remove suppots... but after this post I will probably have same problems as you (we from Balkans are very superstitious as yo know at least I am)
  6. And where did your colleagues buy PEEK and for what price if you know? The problem is that medical grade PEEK is still a bit pricey, but not as much as titanium, right? I saw one company on the internet from the states called Vision Miner which print PEEK and contact them for more info about complications etc. ... they have been printing some implants for hospital in Columbia and all that they could tell me that there were no complications but gave me contact of that hospital so I can ask those surgeons more details , but as today I still didn't.
  7. In Slicer PE, now Prusa Slicer, under Support materials, there is a parameter called Contact Z distance, you can increase it to 0.2 (detachable) which makes removing supports more easily
  8. 3D modeling and printing from US data is pretty much the same as from CT... using treshold technique and generating mesh. The biggest problem, for now, is how to open DICOM data obtained from US because it differs to one obtained from CT in one of the software for sliceing (3D Slicer). For now, in 3D slicer you can open DICOM data from GE machines and Philips but people are working on enabling importing DICOM data from other manufacturers. Hope this helps a little bit
  9. Dear olatif2 when in blender, choose edge select and then ALT + LMB/RMB (depending your preferences) and it should select whole edge (tabula externa) than try SHIFT+ALT+LMB/RMB and select tabula externa and than when both edges are selected pres F and sgould get a facet (closed gap). Or faster way would be to add a new object (cube), size it up, put it below both edges and boolean operation difference and should get closed edges of the skull but slightly lower model than it would be at first.
  10. Dear @madjid_hatefi in the link below you can find some promising steps for making a 3D model with Madison US (it is the same as the mentioned above but with new progress). https://discourse.slicer.org/t/could-not-load-ultrasound-from-mvl-medison-file-format/3928/7
  11. ooh, now I see... totally misunderstand question... I didn't realise that he is talking about conventional angiography, sorry
  12. you have several tutorial videos on this web page how to segment a model. but instead of bones which are in the video, you choose contrast blood to segment. https://www.embodi3d.com/tutorials.html/
  13. And are people from other countries allowed to participate or only for folks from the USA?
  14. If I hear or find out something new I will let you know. Sometimes take a glance at 3D Slicer forum (or link above) and maybe sooner or later something will come up ;). P.S. I know your struggle if something is not free :/
  15. I found in the 3D Slicer forum this topic that may help you. There is software called TomoVision that could help you, but you must buy it. https://discourse.slicer.org/t/how-to-import-a-mvl-file-format-3d-ultrasound-image/3294
  16. I am sorry, I didn't have opportunity to work with that model so can't tell you is it possible to make 3D model. Do you have DICOM data maybe to share?
  17. Wow, nice. Thank you for your true review of MMU2. Unfortunately, new orders for MMU begin in February 2019 and can't wait for it to begin Those prints look great. Are there any difficulties when printing ABS/PLA and PVA as support together in one print? PS. @Dr. Mike is this Palette Mosaic same thing you told me about in RSNA meeting?
  18. @valchanov I am from Croatia, so Prusa is my choice . Yes, taxes can be really high, especially for us in this part of the Europe, right? Last year I saw a really excellent DLP printer (Gizmo) from Australia, but when you sum tax to the price... unfortunately was too high for me
  19. Was it hard to build one from a kit?? Kit is 300€ cheaper than preassembled one.
  20. I am planning to buy this printer and later on multi material update, so please upload some pictures
  21. what is the model of the 3D US? I was able to do model from GE and probably could do it from Siemens Acuson x3000 (I didn't have proper volume, it was my kidney not fetal face ). I tried from Philips US but also didn't acquired right volume (cardiologist didn't know how to do it) and I didn't have much time to read the manual of the machine.
  22. Not much... if you want to make a model from 3D US it depends on who's US machine you are using (there was a problem with GE machines and their Kretz file but thanks to @Andras Lasso he managed to overcome this problem in 3D Slicer). Go to 3D Slicer forum and you will learn how to open and make 3D model from .vol type of files.
  23. Probably, your DICOM data is from CT or MR study of your brain, right? Anyhow, in that case only neurocranium (upper part of the skull) containing the brain was part of the interest in the performed study, so viscerocranium (face) wasn't in the region of the interest (ROI), therefore there is no part of the skull below the middle of the orbit in your DICOM data. Unless you have had trauma and whole head was scanned, than I am not sure what is the problem (maybe damaged DICOM files...)
  24. Dear Aris, as you found out Geomagic Freeform and Materialise 3-Matic for 3D modeling are very expensive (annual license cost between 5000 -11000 € depending what features are included, what field you want to use them for, etc.). But there are also open-source softwares like Blender, Meshmixer, Meshlab (more for engineers), MeVisLab... Unfortunately, Blender and Meshmixer, alone, don't have all these features as Freeform, but if you combine two of them you can make pretty decent models with great accuracy. You should familiarise with that softwares, and there are lots of tutorials available on youtube, and internet pages like https://www.blender.org/support/tutorials/ , and https://blenderartists.org/forum/ ... Hope this helps a bit
