Which is the best software for 3D reconstruction from CT /CBCT images ?

I am a master student of biology and was looking for an alternative (and free) software that can do similar stuff to Fei Amira (viewing and marking structures in single microCT images and creating a 3D reconstruction of the entire stack). Are there any similar programs which can do these tasks?

I do only have access to a Pc with Amira at my university and was looking for software I can try out at my home computer too and maybe achieve similar results.

Any input appreciated!

Thanks in advance!

I am trying to convert stack of ct scan images (fibres/composites) into volume mesh (STEP, IGES format) for mechanical analysis (I'm using Abaqus). I tried using ImageJ, Avizo, 3D Slicer, and python scikit-image but it usually convert into surface meshing (STL) and not 3D volume. Converting from surface mesh into 3D volume is quite challenging and such a pain in the A (lots of errors when export to Abaqus later on and need to clean up manually).

I searched for a while on the net and Research Gate but usually they have problem to convert images to surface format and not volume. I need to convert them into 3D volume since Abaqus can't read STL format. How can I convert directly from image (tiff/jpeg) into 3D mesh?

We also can't afford to buy other commercial softwares like Mimics, Ansys, Rhino... etc.

Thanks.

There are many software available in the internet; MIMIC, Slicer, Simvascular. Which one is easier and convenient to use in term of enough tutorials and resources to learn the process?

I would like to convert medical DICOM data to 3D surface data (STL, IGES) for three dimensional analysis and rapid prototyping for TAVI simulation (transcatheter aortic valve implantation).

We are working on solid foams. Micro-tomography gives very nice pictures, but what we need is getting quantitative information from them : surface area, distributions of cell sizes, window size and strut thicknesses, open vs. closed porosity, tortuosity, etc. We bought Aphelion 3D, which was a quite expensive software, but we deeply regret it as it is a true nightmare, very difficult to handle for non-specialists of programming. And the customer support is almost zero, nobody really helps whereas our needs are very basic. So can you suggest a free and easy software for soing the same ?

Hello,

I created a 3D model of spine using CT scan files (DICOM - 2mm thickness) in 'InVesalius' software. This 3D model can be exported in *.ply, *rib, *stl, *vtp, *obj and *x3d formats.

Now I need to convert this 3D model into a mesh model so that I can add tissue & bone properties and do finite element analysis in ANSYS.

Since I dont have a sound knowledge about CADD, C++, VTK or designing, I dont know how to convert my 3D model into an ANSYS importable model. I want to find the stress and strain between thoracic vertebrae.

Thanks in advance.

Having a series of images from human brain taken from a scan process with CT or MRI, existing in the dicom format, is there an easy way to convert those to a 3D model that could be used in tools like Maya?

Dear Researchers,

I need a 3D photo of a porous material such as attached one only to show the porosity, not for analyzing porous materials.

Can any one help me?

After taking microscopic images under a confocal microscope you can compiled all the optical sections in the form of a 3D image. I need to do this for a few of the stacks (sections) by taking advantage of Image J software.
