stacking images for tomographic representation

I have taken the projection of an object for multiple angles.I have taken iradon, and now i have the cross sectional slices(as row/column matrix). I want to stack every 10th slice along Z in a kinda 3D visualization(with gap between the slices), for showing the corresponding cross sectional slice of the object(like the image specified in the link -http://stackoverflow.com/questions/6283918/matlab-merge-submatrices). I have no idea where to start with. Kindly give some suggestions.

   [n_rows n_cols]=size(my_2D_image);
    my_3D_image = zeros(n_rows,n_cols,Number_im/10); % initialize your 3D matrix
    for k = 1:10:last_image  
      my_3D_image(:,:,(k+9)/10) = my_2D_image(k); 
    end

Thank you so much for your response. this method stacks every 10th slice along Z of the new matrix. I need to visualize this 3D matrix like the image specified in that link. kindly give suggestions.
