I do not know if my problem has already been solved before. I tried to find something about it, but the answers are not exactly made for my questions.
Here is the thing:
I work with microtomography. We use Skyscan 1173 model. I acquire several projections which then are reconstructed so I can obtain slices (2D images) of the entire sample. There is also the possibility to quantify several parameters, such as porosity, and also make a 3D visualization through all those 2D images, that are in grayscale (0-255).
The project I'm working on takes each pair of those 2D images, which were acquired into 2 different conditions of energy. After several mathematics, I obtain 2 sets of different data, which I can then make into 2 different sets of 2D images.
So as of right now, I'm able to use N of 2D images, and obtain 2N of 2D images, N for each variable. Those new 2D images are related to other variables which are not important to describe right now. I changed the colormap and put it a colorbar using matlab so I can easily distinguish several features in my 2D images.
My problem is: I have a bunch of those new 2D images but I don't know how to make a 3D visualization of all this data. I asked it, I searched for it, and all I could find were functions which use volumes (3D data) to obtain slices.
I need to do the exact opposite. I need to use my 2D images, and obtain a 3D volume.
So my questions are two:
1 - Has anyone ever done this before? I mean, maybe a function in matlab or in the file exchange which would allow me to use my 2D images, or even the data, and obtain my 3D volume?
2 - I tried to open my 2D images in the software we usually use, but the software can't seem to identify the colormap in the images. I think it is probably because it only recognizes grayscale and rgb. I made my colormap usng HSV. Is this the problem or is there anything else? Does anyone know how to solve it?
Thanks for all your help.
