Hello, I scanned a shank using CT.

It turns out a lots of slices in tif files. Each tif has the same view, and only part of it is the bone.

So how can I rebuild the 3D model of the shank from this tiff files, and build a coordinates for it, so that I could know like where the cracks are and how it looks like.

I have all the MATLAB toolbox

在 MATLAB Online 中打开

You can tiffreadVolumeor read to import the tiff files. If you have multiple tiff files, you can read them in a loop and generate a 3D matrix Volume of the image stack.

V1 = tiffreadVolume('mri.tif');
whos V1
  Name        Size                 Bytes  Class    Attributes

  V1        128x128x27            442368  uint8              

Then you can use isosurface to visualize it.

isosurface(V1)

If you have the images in DICOM (.dcm) or NIfTI (.nii) format, you can open it in with the Medical Imaging toolbox.
