  1. 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

    Skull is seen as two shells

    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.

    Converting Ultrasound Files

    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

    image extraction

    ooh, now I see... totally misunderstand question... I didn't realise that he is talking about conventional angiography, sorry

    image extraction

    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/
  6. And are people from other countries allowed to participate or only for folks from the USA?

    Converting Ultrasound Files

    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 :/

    Converting Ultrasound Files

    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

    Converting Ultrasound Files

    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?

    Wich US is a study made on?
  11. 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?
  12. @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
  13. Was it hard to build one from a kit?? Kit is 300€ cheaper than preassembled one.

    I am planning to buy this printer and later on multi material update, so please upload some pictures

    3D Printing My Skull

    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.

    3D Printing My Skull

    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.

    3D Printing My Skull

    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...)

    Best CAD software for anatomical modeling

    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
  19. Here are two volumes obtained by GE Voluson E10 and exported as .stl file. I think that a lot depends on fetal head position and gestation age if you want to have nice fetal face model. Personally, I wasn't present when study was made.

    Vessel reconstructions

    Dear Jee Lee, if CTs are done in arterial phase you will hardly be able to show venous system by automatic segmentation, maybe if a really late phase more porto-venous phase is done you will have some more success. I would suggest that if you have arterial phase only, try automatic segmentation for arteries and try manual segmentation for veins. Or obtain porto-venous phase CT study.

    Femur DICOM

    Dear @kreeser1 under Downloads you can find a lots of DICOM data and .stl files for download. Here is something I found, maybe it helps https://www.embodi3d.com/files/category/44-extremity-lower-leg-cts/
  22. I contacted one private clinic in my city which has 3D US, and they are apparently really good at it. They told me that they are too busy right now so I couldn't obtain new DICOM data, but I will call them again and ask them if I could come. But the doctor who works there told me that they have GE Voluson S10 (newest model) which have build in the possibility to save study as .stl file... same as Philips IntelliSpace portal that was told before. I did a little bit of research and really there it is, but not for S10, yet for E10 model: http://www3.gehealthcare.com/en/products/categories/ultrasound/voluson/voluson_e10#tabs/tab44799EF6884146E1A27A6929FCAB17D5 Keep your fingers crossed so I could have a glance at that machine in a very soon time
  23. Hi everyone. So, I didn't want to write anything until I make a model from US, but unfortunately, I am still in process of making one. I managed to save study in DICOM data, BUT :(, I have only one file (not several as in CT studies). When I try to upload that data in 3D Slicer it says that that file doesn't have volume (geometry information). I contacted 3D Slicer help and they couldn't help me (they advised me to try to check data by myself)... since I am not so familiar with software and data, I have contacted official service for GE in my country and they said that, probably, the problem is in 3D Slicer, that it can't read dcm data from GE machine. Since I don't have access to 3D US machine (it is not in my department and I depend on one colleague during clinical program/exams and his shift one day a week), I am now stuck. As soon I make some progress I will let you know, or if anyone has any suggestions, please help me or let me know :).

    FDA Legality Question

    FDA approved software (MIMICS and 3-Matic from Materialise) must be used only for implants design (as said in 3D SIG and FDA meeting last year). Regarding making patient specific models for surgery planning etc. you can use other software (open source). @Dr. Mike correct me if I am wrong, since you are from the States

    How to section a skull in half

    I agree with dr. Mike. Try also in Meshmixer plane cut option. Just simply choose which side you want to cut and cut it (you will find some videos on youtube how to use plane cut in Meshmixer).
