Clear Blood Vessel Segmentation in 3D image using VTK

Question

I am using vtk for segmenting blood vessels. I have two dicom image sets,one has normal CT images and the other has CT with MIP(Maximum Intensity Projection). So i subtracted the two series and gave that result to the input of vtkMarchingCubes.But my segmented image is showing only less details.I have attached what i got in the picture. https://i.stack.imgur.com/V66nN.png

I tried using filters but no use

I need to get even the thin vessels.How is it possible using only VTK? If not How is it possible in ITK.

If my question is not clear kindly inform

Answer 1

I recommend to use 3D Slicer and then download VMTKVesselEnhancement for it and to identify tubular shapes in your 3D images and then using segmentation methods to extract the 3D surfaces of the blood vessel.

Answer 2

In ITK, you could use vesselness filter to enhance the vessels. That should make them easier to extract.
