[Insight-users] DICOM 3D segmentation

[Jon Haitz Legarreta]

Hi,
segmentation is highly dependent on the structure/tissue of interest and
the modality you are using.

As for the pixel type that best fits your image, (signed) short is a common
choice for CT images. As for the seed point, make sure you take into
account the ITK's axis/orientation conventions, as well as the ones your
viewer may be using. You may find it useful displaying your seed point so
that you can see that you are actually placing it where you want/expect it
to be.

Most ITK filters are templated over the dimensionality, so you will be able
to segment images no matter they are 2D or 3D.

You may find it useful to have a look at the ITK software guide to explore
some built-in segmentation methods and examples:
