Hi, I am very new with the 3D slicer, so my question might be so simple. Still, it is really appreciated if you could help me with it. I have a DCOM data from CT of a bone (to say like femur). I am wondering how can I do the followings: #1 I want a surface model of the bone to be created just onl…

If the image quality is good enough then thresholding, smoothing, and inverted island removal may produce good enough results. See detailed description here: 2D/3D fill tool If image quality is very low and/or bone density is low then you may need to use Grow from seeds effect (growing bone from se…

Dear Andras, Thank you very much for your prompt reply! I will follow the instruction and information provided, and if I face any concerns, I will come back to you again. Really appreciated! Saeed

Dear Andras, I followed all the discussions you have had with the other regarding creating a 3D model of a bone, generating 3D mesh, and eventually importing into FEA. I should, however, say that I am still a bit confused about the process for making the model. Actually it is very hard to do so an…

[image] saeed_mouloodi: Actually it is very hard to do so and it leads to inaccurate results. Development of a new segmentation workflow for a certain bone image, acquired with a specific imaging protocol, for a specific application always takes some time and practice. If the generated mesh s…

Your detailed and one-by-one replies are greatly appreciated. By the information provided, it seems a bit more understandable what steps I should follow right now. I will proceed and have a try and hopefully after generating a successful result, I will make a video of it and will share it with you…

[image] saeed_mouloodi: it seems that 3D slicer does not generate a 3D geometry (I mean a format file like STP or STEP) to be just a 3D model (not meshes) Since 3D geometry, 3D model, mesh, part, solid are used for completely different things in different domains (3D modeling, FEA, medical im…

Thanks again dear Andras. I will start again to generate the meshes from the comments you have mentioned so far, and I let you know then. Probably it takes a bit of time, since I would like to try everything with enough details and with importing the model into FEA and running some simulation. I ho…

Hi again, As you mentioned I tried to generate the meshes on the long bone. Since my region of interest is ONLY the bone, I merely used TetGen in the “Meshing method” appeared in the inputs of segment mesher extension. Because as you highlighted Cleaver generates a mesh for background, which I am n…

TetGen: Unfortunately, TetGen is known not to be very robust. You may try to adjust meshing parameters. Cleaver2: The background mesh should not be a problem. Each cell contains ID of the segment, so you can use vtkThreshold filter to extract cells corresponding to a specific material (see this exa…

Dear Andras, Following a great deal of time and put significant effort along with several trial and error, eventually I have generated a 3D model from the DICOM files, which can be imported into any CAD software as I eventually end up with a STP file format. This facilitates importing the 3D model …
