There are several programs for converting MRI or CT images into a 3d model. To create a XNUMXD model from .dcm images, we use InVesalius... This program is not only convenient and easy to use, it is also available for most platforms: Windows, Mac OS, etc. The program is free and open source.

After installing and opening the program, we get to the main menu. Where to download our original DICOM images.

If your computer does not have enough RAM, the program will offer to reduce the original resolution of the images.

After import, we will see a window with images of our tomography. In the second window, it will be necessary to adjust the areas that we want to transfer to the 3D model.

In the third window, we need to create a new surface.

This surface will be the skeleton of our future model. We give it a name.

As you can see, our three-dimensional model appeared in the lower right corner.

We just need to go to the fourth window and export 3D surfaces.

Give the file a name and save it.

Let's check the result in MeshMixer.
