I have 3, 2D Image file (RGB) with same dimensions. I want to creat a 3D image by stacking of these 2D image but I dont know which code I should use. I tried some codes suggested here but could not get any image. Please suggest me how to solve this. Your help would be appreciated.

Hi,
Kindly make use of cat function to create a 3d image from 2d images as shown.
Only valid for Images that are already reconstructed by the CT Instrument.
In the case of 2D Images that are projection of volume along different angles will require filtered back-projection reconstruction (radon) process to build the 3D image.
image3d = cat(3, slice1, slice2, slice3, slice4);
In order to Visualize the created Image make use of implay(array3d) to view different slices at different Instances. Make use of the following code to visualize a volume in 3D.
Kindly go through following links for reference:
Thanks

Dear Prabhan, Thank you very much for your answer, but my question is, I have captured 2D images (Suppose 3, 2D images) which is not by CT Instrument. These 2D images also has information of z axis. Now I need to convert 2D image in 3D image which can show information of all three axis. Now I want to do mathematical operation between these 3D images so that I can go for stacking of images obtained after mathematical operation.
Can you help me to provide some references for this kind of problem? Any suggestion from your side will be highly appreciated.
