micro CT slices to 3D image of the object

I have multiple tiff slices of a material made by micro CT I want to get a 3D image of the object .Please any help

[Walter Roberson]

tiff_filename = 'afaf28g.tif';    %use appropriate file name

num_slices = 0;
while true
   try
     this_slice = imread(tiff_filename, 'index', num_slices + 1);
     num_slices = num_slices + 1;    %only get here if read worked
   catch
     break;     %normal to get here at end of slices
   end
 end

data_slices = cell(num_slices, 1);
for K = 1 : num_slices
   data_slices{K} = imread(tiff_filename, 'index', K);
end

Now you can go through the process of determining whether all of the slices are the same size, and if not then figuring out where you want to pad them.

After that, to visualize you can consider slice() or isosurface() or the File Exchange contribution vol3d v2

thank you so much for your answer , I tried with the slice and the isosurface but it wouldn't work , could you explain futher please ?

[Image Analyst]

MATLAB has very limited volumetric image visualization capabilities. It's pretty much limited to isosurfaces and cutaway views (slices). If you want more powerful capabilities you'll have to look to a program like Amira or Avizo which are built for that kind of thing.

@Image Analyst I have got the information of void volumes and its cordinates from micro-CT data. May I know whether I can reconstruct these data to generate 3D void distribution in Matlab?
