3D reconstruction from 2D images

I have come across an example of surface2volume function from https://www.mathworks.com/matlabcentral/fileexchange/8772-surface2volume .I had tried the example given and it work! My question is how I gonna to modify the coding so it can be used for my own ultrasound 2D images? Because the example coding is loading the mri mat file.The example coding is as below:

    load mri;
        D = squeeze(D);
        D = padarray(D,[5 5 5],'both');
        % Create an isosurface
        Ds = smooth3(D);
       surface = isosurface(Ds,5);     
        % Display the surface
       figure;
       subplot(1,2,1);
        hiso = patch('Vertices',surface.vertices,...
                    'Faces',surface.faces,...
                    'FaceColor',[1,.75,.65],...
                      'EdgeColor','none');
        view(45,30) 
       axis tight 
      daspect([1,1,.4])
        lightangle(45,30); 
        set(gcf,'Renderer','zbuffer'); lighting phong
       isonormals(Ds,hiso)
        set(hiso,'SpecularColorReflectance',0,'SpecularExponent',50)
          % Reconstruct the volume and display it as montage
       OV = surface2volume(surface,[],1);
        nDims = size(OV);
        subplot(1,2,2);
       montage(reshape(OV,nDims(1),nDims(2),1,nDims(3)),[0 1]);

Hope you can clear my doubt.I am a newbie to use matlab. If you got any solution to stack 2D images into 3D or can reconstruct 3D from multiple 2D images please feel free to comment here.Thank you very much!

Hi guys

I have used this code as well to convert a 2D image to volume. everything is fine until the line 23"nDim=size(OV)". then I am getting this error: 'The logical indices contain a true value outside of the array bounds'.

Any body can help?

That sounds like you might have defined a variable with the name size.
