OrtogOnBlender add-on: Import DICOM voxel data on Blender

10

cogitas3d writes:

After a lot of study about DICOM file structure, finally the OrtogOnBlender add-on allow the users to import slices of a tomography into Blender and they can also view the structure in voxel data style.

More than that, the users can interact with the model, positioning meshes along the object, as we see in the video:

Remember that OrtogOnBlender also offers the option to rebuild 3D tomography!

The option is available for Linux and soon, will be ported to Mac OS X and Windows.

I take this opportunity to thank the entire community that develops robust libraries and solutions, when united, allow tools like OrtogOnBlender to help specialists to save lives!

  1. My friend, I think You are doing wonderful and amazing job! People like You build better world for our children:) Greetings from Poland :)

    From a brief look at the source code it looks as if 3D triangle models are generated by an external program. In the video that is quite fast.

    I have done some work on building models from volume data, and it can be quite tricky. Especially when trying to make simple printable STLs from complex bone structures (animal skulls...).

    • Back before 2.8 there was a way to import volumetric textures and render them using the internal renderer, even in real time(-ish). I haven't yet figured out how to use file-based volumetrics in cycles or eevee, though it may be possible.

      The difference is that most 3D representations of CT images creates an isosurface model. A more computationally expensive approach is to use raycasting or even raytracing with the actual volume texture.

        Yep, nice nice visualisation of such data is pretty much challenging.
        Nice to see possible solutions in this area
