Explain why cat() did not work for you.

try cat(3,...)
image3D = cat(3, slice1, slice2, slice3, slice4, slice5);
You could put it into a loop
for slice = 1 : totalNumberOfSlices
thisSlice = GetSlice(); % Whatever you have to do to get one 2D image.
if slice == 1
image3D = thisSlice;
else
image3D = cat(3, image3D, thisSlice);
end
end

Stelios, did you see the comment after it "% Whatever you have to do to get one 2D image."??? That means that you have to have some code to get the slice. You have to write it. I'm not writing it.

The problem is not constructing the 3D array: the problem is displaying it. MATLAB does not have good voxel visualization routines. You could try http://www.mathworks.com/matlabcentral/fileexchange/3280-voxel

Depends on what you mean by 3-D Image reconstruction. Usually instruments have this built-in. For example if you have a CT, MRI, or confocal instrument, those instruments have software to reconstruct the 3-D image.
If you want to do visualization on the reconstructed volume, we use Avizo:
